Most people say 160 degrees F or hotter.
I run mine at about 110 or 120 degrees and it runs fine, but I would like to get it a little bit hotter. I ran it without any heat at all for a while and it ran fine, but I'm not sure how long the injection pump would last like that. I've heard that they don't like the thick oil.

I have read that to be safe for all diesel engines the oil needs to be at least 180'F.
The 6.2 isn't picky about, any thing.
So we can say 180 at most and 110 at least.
I think 160 would be good?
I need to rig some thing up so I can do flow tests.

No, the 6.2 really isn't picky. Just about the only thing it is picky about is that it doesn't like any air bubbles at all in the fuel. One other thing I have found in my veggie oil experiments is that any restrictions in the fuel system are not good. It doesn't like to pull up oil that is very thick, and it is also very sensitive to clogged fuel filters.
110 is just something I made up, really. That's basically how hot it needs to get so that the lift pump will pull the oil up in colder weather (40 F). I would rather have it closer to the 160-180 degree range.
Of course, my veggie setup is about to undergo some major upgrades... The new setup is going to be completely thermostatically/electronically controlled and almost completely automatic. It will also add the capability to run veggie in weather barely above zero (F). Instead of using coolant heat alone to heat the oil it is going to use a combination of coolant and electric heaters. Now if I could only find time to build it...

It's not really a matter if the engine likes it, or not. It's injection pump life. A rotary type injection pump is absolutely the worst candidate to use with vegetable oil. All 6.2s and 6.5s have rotary pumps. I suspect though, that short pump life often goes unnoticed. A Stanadyne pump used properly with good fuel and correct temperatures can often last over 200,000 miles without a teardown - but often the timing advance housing gets worn and sluggish by the 100K mark. Use the same pump with vegetable oil, and often the life of the pump is cut in half or less. So, how many are going to notice a pump going bad in 75K or 100K instead of maybe 200K? Not many, I suppose. There has been a lot of metal-parts wear testing done by the U.S military and also many agencies in Europe and a few third-world places. Threre are many more diesel cars and trucks in other parts of the world - so pump wear in those areas gets much more attention. There is a lot of scientific data to support the wear problem with certain alternative fuels. But, that being said - when you can buy a "rebuilt" pump for $300 - maybe it doesn't matter anyway. You could save quite a bit of money using alternative fuel - if you do it correctly and get the oil for free.oil pan 4;1558862; said:
In regard to running on it - main hurdle is cold starting - and cold weather. Just like the old multi-fuel farm tractors built in the 30s, twin fuel tanks are needed. Start on diesel, then once warmed up, switch over to the alternative fuel, and switch again before shutting down.
Back to pumps - in-line piston pumps last much longer than rotary pumps - with any kind of fuel. If you had an in-line pump on a 6.2 (there is no such thing though) - there would be a separate fuel injection pump for every cylinder instead of one dual-plunger pump doing all the pumping for all eight cylinders. So, that alone makes the in-line pump much more durable. Some Mercedes, Isuzus, Cummins, Detroits, Fords, etc. use in-lines. The rotary pump can have wear problems with alternative fuel in the distributor section of the pump - and an in-line pump has no distributor. This section in the rotary pump (head & rotor) is also the most expensive part - and if you sieze your's up - many pump shops will not accept your old pump for a core.

Most of the problems with injection pump wear on veggie oil are due to poorly filtered fuel. With clean oil the pump can last as long (or longer) on veggie than it will on #2 diesel.
Seems your test results differ from those the US Government, Stanadyne, Cummins, CAV and many places overseas have done.High Sierra 2500;1560002; said:
There is ample scientific evidence that shows the increased wear patterns due to the lubicosity differences in most blends of SVO and many temperatures. Overseas they usually add canola oil to bring the lube specs up. Yes, of course temperature and filtering is an added problem - but not the only one. Such problems exist with any fuel - not just vegetable oil.
Also, running diesels on alternative fuel - in this country - seems to be a new thing to many people. It's been done for well over a 100 years. But, the rotary pump was not invented and put into common use until 45 years ago - and alternative fuel use in rotary pumps is sort of a new thing.
I suspect you are offering anecdotal information on the subject. If not - tell me what data you are using. Have you driven your truck 200,000 miles on SVO?

No. Have you?
Veggie oil is actually a better lubricant than diesel fuel and when it doesn't have a bunch of dirt in it the injection pump will last at least as long running veggie as it will on diesel. The dirt in the veggie is what kills the pump, not the oil itself. It is stupid to think that the oil makes the pump wear faster.
New IP around $260.
Now use free fuel and have it have it last 100,000 miles
Or
Keep pumping diesel in there at the rate of around $2.50 a gallon and have the IP last maybe up to 200,000 miles.
Hmmmmmmm.
I have a nice 5 mic filter laying in one of my tool chests collecting dust, I will incorperate into my design.
I was just going to use another G3 or G12 pre filter just to catch the trash but I will add in the fram 5 micron too.

Hmmm - I guess to you - "oil is oil" and it's all the same. Good thinking, do you dump deep-fry oil into your crankcase? That sounds pretty silly to me. Either you are ill-informed, or your grasp of knowledge greatly exceeds mine and I simply cannot comprehend all this.High Sierra 2500;1560080; said:
I have worked on several injection pumps that failed after longterm use of heated and filtered deep-fry oil from Mcdonalds et al. I know people that were running on waste oil back in the 1960s in Mercedes cars. Later pumps I've worked on with waste-oil use include one from a 6.2 GM, two from 7.3 Fords, one Diesel Kiki, and several from Bosch VE rotaries on Volkswagens. But, I can say the same for pumps run on pump-diesel. My first-hand experiences with such things are not scientific - since there are no "controls" involved. I cannot verify actual miles, fuel quality, etc.
"Word of mouth" about such things is often interesting and useless at the same time. Few people using watse oil and driving diesels know much about the internals of their injection pumps or the actual chemical content of the fuel being used. I worked as a pump rebuilder and a diesel mechanic for close to 40 years - and there's lots I don't know. That's why, to a degree, I rely on scientific testing done by large agencies. Yeah, they often have their own agenda and fudge things a bit - but there are some things they cannot lie about.
I don't know where you get your waste-oil - but I suspect you have little control over it's content. McDonalds is in the process now of changing their deep-fry oil chemical content. It is better of worse? Are you read up on it? Many types of bio-oils are better for lubrication than standard pump diesel - e.g. rapeseeds, soy, canola, etc. So, when someone talks about the pros and cons about any type of SVO, you have to know exactly what sort of blend is being discussed. Some SVO blends are very good and better for pump life than pump diesel-fuel. And others are terrible. Stanadyne is coming up with fuel additives - to put into low-sulfur pump diesel - made from bio-deriviatives e.g. rapeseed and soy.
Again - of all the pump designs - rotaries are the most intolerant to alternative fuels in regard to wear. That is an undisputed fact and easily verified. But, in regard to Stanadyne, they've had many problems with thin or certain low-sulfur diesel fuels right from the pump. The SVO thing is in addition to all that. I don't consider it a problem worth worrying about - since I do all my own repair work. And, even for someone that might have to buy a rebuilt pump every 100K - it's not necessarily a big deal. There is cost-savings potential for using waste-oil depending on how it's done and used. But, many times there is no savings at all - in the long run.
Here's a piece of an article about the postive benefits of some types of bio-additives - much of this from Stanadyne Corp.
.. "In the Stanadyne White paper on diesel fuels, it reports that "problems with increased wear have been encountered in both countries (Sweden and Canada). Wholesale introduction of the low sulphur fuel in Sweden had disastrous effects on diesel engine operation and resulted in a crisis situation for Swedish refiners and a European rotary fuel pump manufacturer. Swedish refiners are now using additives to prevent excess wear in fuel injection systems and their problems are apparently under control. Certain major Canadian refining companies are adding lubricants before delivering fuels to the customer."(11)
Fuel injection manufacturers have adopted the use of the High Frequency Reciprocating Rig (HFRR) to test the lubricating properties of diesel and have recommended that all diesel fuel meet a minimum limit of 460 micron maximum Wear Scar Diameter (WSD). For the HFRR test, a lower scar measurement indicates better lubricity in the fuel.
Stanadyne Automotive Corporation, one of America’s largest fuel injection manufacturers, has been testing Bio-diesel at varying concentrations as a fuel additive in both Number 1 diesel (kerosene) and Number 2 diesel (fuel manufactured to meet the 500ppm maximum sulphur content).
Their test results showed that for Number 1 diesel (kerosene) the addition of 2% bio-diesel reduced the HFRR wear scar diameter to 355 microns while the addition of 1% bio-diesel to Number 2 diesel, reduced the wear scar diameter to 321 microns.
Based on the HFRR tests conducted by Stanadyne, they issued the following statement.
"…we have tested bio-diesel at Stanadyne and results indicate that the inclusion of 2% bio-diesel into any convention diesel fuel will be sufficient to address the lubricity concerns that we have with these existing diesel fuels. From our standpoint, inclusion of bio-diesel is desirable for two reasons. First it would eliminate the inherent variability associated with the use of other additives and wether sufficient additive was used to make the fuel fully lubricious. Second, we consider bio-diesel a fuel or a fuel component-not an additive…Thus if more bio-diesel is added than required to increase lubricity, there will not be the adverse consequences that might be seen if other lubricity additives are dosed at too high a rate."
As we move from low sulphur diesel to ultra low sulphur diesel (which has a maximum sulphur content of 15ppm), the quality of diesel fuel will worsen, and all that will be necessary to counteract the associated problems is to elevate the level of bio-diesel.(12)
A recent research project funded by the Saskatchewan Canola development Corporation, to evaluate the efficiency of commercial and vegetable based lubricity additives found that Canola Methyl Esters (CME) and a Canola Oil Derivative (COD) preformed the best in these lubricity tests. The CME’s were effective at treatment rates as low as 0.1% (1000ppm) and were shown to be very cost effective.
The project concluded that, "The application of Canola based lubricity additives in both unadditized and commercial low sulphur diesel fuels has been shown effective in reducing engine wear by as much as one-half, thereby potentially doubling diesel engine life. Fuel economy gains of up to 13% have also been recorded… The engine wear reductions and fuel economy improvements appear to be directly related to diesel fuel lubricity.
Based on these encouraging research results, it is concluded that the Canola lubricity additives could extend diesel engine life and fuel economy when applied in hydro treated, low sulphur diesel fuels. It would seem prudent for refiners to more thoroughly investigate, and seriously consider the production and introduction of these effective Canola based lubricity additives to their future mid-distillate fuels."(13)

"New" injection pumps
That compounds reports of failed pumps - unless they are on brand new vehicles. Otherwise, it gets kind of hard to tell what caused what, and when.
When it comes to savings - some people want to buy a diesel and run veg. oil and know nothing about any of it. Often they are paying a shop rate somewhere of $80 per hour for any installation, repair or diagnosis. And, sometimes buying - premade - hyped-up fuel treatment equipment. These types of users often lose money in the end - sometimes lots of it.
A person that knows diesel mechanics and does his/her own work is a whole different story. And with the 6.2, parts are pretty easy to find and cheap.
I've been using waste oil since the early 70s - including cooking oil, waste motor oil, etc. But for me, unless I get it locally - it's hardly worth the bother anymore. What was once a good thing is quickly getting ruined - partly because so many people want to bring attention to the whole deal. Many places in my area no longer just give the waste oil away. Theres a company 100 miles from me now - that has gone into business refining and selling, at the pump, bio-fuel. They have started buying up serveral types of farm bio-fuel ingredients including soy, grass, and corn, and well as paying a small fee for waste cooking oil. They are currently selling their bio-fuel for around 10 cents more per gallon than diesel - and people buy it. And, then there's the tax thing. Not a problem here in the US - yet . . . but just wait. In England, it is now illegal to use cooking oil for fuel - because it's considered tax evasion. If enough people get using biofuel - there will surely be a tax put on it. And, when bio-fuel goes full scale - it will be a total losing proposition. There will be more petroleum used to produce the "bio-fuel" than it would take to just make good-old-fashioned diesel fuel. I own a farm and try to keep up with all the bio-trends. Dairy farming is just about dead here - and the only profit from making milk is from government subsidies. I am also a maple syrup producer - and use a lot of waste oil for that. I'm in central New York, and there are many efforts being made to get farmers to grow corn, soy, and perennial grass for bio-fuel production. And, this farming gets done with fertilizers made from pertroleum, tractor fuel made from petroleum, pesticides made from pertroleum, refining processes run on petroleum, and electricity made with buring coal.
I doubt your $260 pump is new. That's another thing that can screw up success or failure stories about longevity of injection pumps. I don't believe you're going to find a new Stanadyne DB2 pump anywhere new for $260 - except for a few un-warranted military suplus units. Last I heard prices start in the $900 price range for new ones fresh from Stanadyne. I'll buy ten of them, right now, if you've got them for $260 new. The "exchange" pumps sold in the $250 - $350 price range do not get all the moving parts replaced. In fact, some of the most expensive and major parts get reused - over and over. So, when you buy a $260 pump you are buying a used pump that has had several small parts and seals replaced, tested and adjusted to perform properly when you get it. Many if not most do not have the longterm projected life as a brand-new pump. In fact, read the small print from most pump shops - and youll often find that you do NOT get your core credit if certain major parts are bad in the pump you want to trade in. Next time you buy an exchange pump, ask if it's warranteed for vegetable oil use.oil pan 4;1560094; said:

What they are referring to - is certain vegetable oils that have excellent lubrication - certainly not all vegetable oils. Stanadyne wants to use some of them as an lube-additives to mix with ultra-low sulfur 2007 pump-diesel. I supect part of that is so they can sell something that sounds "green" and environmentally friendly. The generic term "vegetable oil" has little meaning in itself. Same for other terms like "bio-fuel", SVO, or "Willy Fuel" (Willy Nelson's bio-fuel). Rape seed, soy, and canola are some of the most commonly used at present that are known for good lube. I've got test specs. on over fifty types of grains, grasses, and beans that have been experimented with all over the world. Some forms of waste cooking oil has low lube qualities. I kind of wonder now, with cooking oil chemistry changing, if it's going to be better, worse, or the same. The standard "trans-fat" oil has been banned in New York City. McDonalds is also dropping it, and other's will follow.superjeer;1560722; said:
For bio-derived fuel, the search is on for something that virtually grows by itself and makes good fuel. Corn doesn't work - since it takes a lot of petroleum to grow it. In New York, perennial grasses are being experimented with. I was looking into it myself - and if the government subsidies get high enough - i might try to grow some.
When it comes to buying fuel - it's not always easy to know what you're getting - even with pump diesel and all the recent changes that have been made. I suspect though, it's even harder to know what you're gettting with cooking oil and such.

There are plenty of natrual and organic pesticides.
That can be done on farm using alternative energy and you can make even better profit.
Well you can use solar, water, wind, bio diesel and a good old fashioned generator.

one thing i can add is that most of the companies that make IP's and engines, for that matter, are totally clueless about the use of alternative fuels. They don't care because they don't make money off it. I talked to someone from tech support at stanadyne and all he said was that you can only use B5 in their pumps "because of lubricity". He didn't have a clue what he was talking about, just reading from a joint statement made by several IP companies who are all equally clueless because they have not done much research at all.
Another thing i can say is there are a lot of people running veggie through their pumps that have no idea how much emulsifed water could be going through because they do not properly dewater their oil even though they filter it. Free water will stop a pump like ours immediately but emulsifed water will damage it more slowly. I suspect that is a major factor in what shortens the life of these pumps and probably has a lot to do with what jdemaris is talking about.
Properly heated, filtered and dewatered wvo should, in theory, not shorten the life of an IP and could possibly make it last longer. I have read a lot of cases of failed IP on the various forums but most of them were due to mistakes in the filtration part of it.
A good idea for anyone running wvo is to install a temp sensor just before the IP, even a cheap engine water temp probe from autozone for like $16.99, mounted in a T with insulation, will give a pretty good idea of how hot the veggie is.

Fireball - I think you're dreaming
Even Gerber babyfood is leaving. They've had huge fields here for years -but are pulling out after deciding that northeast farming is not cost-effective.
You don't seem to know much about cow manure either. A typical mid-sized 75 cow dairy farm might have 150 acres in corn, hay and alfalfa on any given year. 75 cows can't even come close to providing enough manure to enrich the soil to grow corn. And hay? It needs nitrogen - and also tons of lime every few years to keep the soil from getting too acid. And - back to those 75 cows - they need good grain to make milk - and grain prices are high. Every farmer spreads all the manure on at least a daily basis, and crops are always rotated to an extent. But - dairy farming requires certain types of crops - and when a person is farming his/her own land - you can only rotate just so-much. Out west where there if Federal land to use, things can be a little different.
Farming is also very labor intensive, and it's getting impossible to hire anyone for farm work for many reasons, financial and safety related. Traditionally, many farms were generations, and the whole family worked them. Not anymore - except for a few of the Amish farmers we have in the area.
Why don't you come to this part of the Northeast and tell all the farmers, and-exfarmers - and corporations like Gerber - what you know - that they don't.
And, your comments about solar, water, wind, etc. ?? I think you're still dreaming. A typical solar-electric installation in a good sun area will pay for itself in around 30 years. Installation cost is usually around $8 per watt. Average farm uses over 1500 KWH per month. Do the math. To even come close to meeting that electric demand, you'd need a 20,000 - 30,000 watt photo-voltaic system. A 30,000 watt system could cost close to $250,000. It's a nice thing to have for independence, but does not provide cheaper electricity than is currenty available from the grid. I've got a 4200 watt grid-tie solar electric system here, and a 2000 watt off-grid system at my other place up north. My wife is an asst. director of a water-powered grist and saw mill. And generators ? I've got half a dozen - a 20 KW detroit diesel power 1300 RPM genset., a Homelite 4400 watt portable, a Fairbanks Morse 15 KW Contiental powered genset. a PTO power 13 KW generator, and a few assorted small ones. Funny thing I've noticed with all - they all use fuel.
I think you're dreaming. Doesn't sound like you know very much about dairy farming in the northeast. If the plug was completely pulled on government backing on milk-prices supports, the remainder of the few dairy farms would be gone. My town had fifty large dairy farms 20 years ago, we now have three left -and they're struggling. And, they are only surviving because they own most everything and are not burdened with debt. Same goes for farm equipment dealers. I worked for a John Deere dealer unit the place closed in 1991. 30 years ago - we had a Case, Allis Chalmers, Ford, Deere, and an International Harvester tractor locally - now they are all gone. Even the Agway stores are gone.fireball;1561118; said:

Yeah - you're dreaming again. Price some of the organic supplies. There are a few small scale specialty crop farms that focus on niche products - e.g. organ peanut pototoes, certified organic beef, etc. When they have contracts with specialty buyers - then they CAN affort organic supplies, and/or use farming methods such as culivation and intercropping. But, it's not viable on a large scale. The small specialty operations come and go, all the time, as demands and fads change.fireball;1561118; said:

:exactly:
Did I say that all oils are the same? No. Would I run an engine with veggie as lube oil? Definitely, if I could find a veggie oil that was thick enough at high temperatures (and I wouldn't be the first one to do it, either). Most veggie oils get very thin at high temperatures so they aren't suitable for that application.
I don't think that all oils are the same (they are obviously not). It is absolutely stupid to think that an oil with a better lube property than another is going to cause something to wear more. There is no reason it should if the two oils are both clean, dry, and the same viscosity.
Trust me... I am plenty well read on this subject. I am using a canola oil from a coney island. True, I have very little control over the oils content when I pick it up, but before it goes in my tank I know exactly what is in it. The truth is this... Most veggie oils are a much better lubricant than any ordinary diesel fuel. What makes the pump wear isn't the oil, it's the contaminants and water (as GREASE FIRE pointed out). If you have clean, dry oil it won't hurt the pump at all.
