Go to Maintenance and Fluid section. On the sticky there is lubricity study. Click on that and read the report. That is the best report instead of opinions.

Diesel fuel is the same for everybody regardless of the engine.

PS: What I mean with the last statement is the study is done independent of engine. I don't claim I know anything about Cummins or PowerS. However, I know 6.5. While it is not exactly the same as other engine, the additive in the study should be a good way to choose your additive based on availability and money.

 

Different engines do have differnt fuel needs. What someone with a new truck uses might not be good for what you can use, and what someone else uses for a similar year Cummins or something might not work well either because our injection pumps are different. Newer diesel injection pumps have been made to run with less fuel lubrication, even though most people will still add them.

First, if using #2 ULSD, you should add lubrication with every tank. the best value is cheapest non-detergent SAE30 or TCW3 2-stroke oil. 1qt max to a full tank, 1/2 quart min.

Second, our injection pump has an optical sensor (OS), which means it has to see through the fuel to get a cam timing reference. So you can't use a lot of anything dark.

Third, because of that OS using anything with a solid lubricant is bad, as you dont want it sticking to the "eye" of the sensor.

Fourth, also because of the OS, using heavy detergents/solvents can pick up crud and cloud the fuel and cause OS codes. Not that a cruddy fuel tank and lines is a good thing, but you just have to know what to expect.

 

I add stanadyne performance formula per recomended dose to every fill up, and 2 cycle oil too....

 

i,ve been adding the two stroke oil,.and i,m wondering about it gumming up the optic sensor,..

heath told me a qt of the cheapest motor oil and some stanadyne. i use about 1/2 bottle of stanadyne to 20 gallons (he said it helps to keep optic sensor clean)
and a qt of motor oil.
todd said he runs 4 qts of motor oil w/a bottle of stanadyne in his fuel in his rig when he tows.
im running close to 2qts per tank for a little while for new ip and injectors.
i think the PS silver can is similar to stanadyne, it smells just as strong.
they are a solvent, not really any lubricity in the solvent based additives, you need oil for that.
bill heath has told me he doesnt see much use for 2stroke anything in diesel.
the motor oil is what he told me to use.
i use what they say
you have to have something. the ULSD is just too low for lubricity.
the sulfur is not the lubricity, it is the process of removing sulfur that strips lubricity.
the best is bio, even 5%.

Can you specify motor oil grade. I have 32 gallon tank. How much oil? Do you add oil into empty tank or full tank. Much appreciated.😊

 

I wonder if Heath will provide lubricity numbers for motor oil. The study done used some USED 15W-40, and it did almost nothing for lubricity.

If using 4 quarts of oil, is that used? That would cost more than a gallon of diesel, or is that much needed to add enough lubricity?

2-stroke oil on the other hand provided very good lubricity.

 

The best of the list was Biodiesel. USe this link to find it near you.

1 Gallon per 25 gallons or so.

in my truck, i use 10oz cheap TCW-3 2 stroke oil, and a squirt of power service white ( i'd use grey in the summer, but i got 3 bottles of white for free ) . Some say you can notice a difference in how the truck sounds with the 2-stroke, but i think it may be psychological. It definitely helps with lubricity

 

The 2 cycle oil I use is blue, not red, and it does tint the diesel blue, but I have been doing it since I have had the truck and have had no trouble with the OS. I get it from walmart, by the gallon.....

 

I use a blue TCW-3 for more than a year now, with no issue.

 

So If I were go to the local store and get something, Just get a quart of Oil and maybe some other additives? (either the Gray or white bottle)

Closest place for Bio is about 25 miles away.

closest for me is 40, so you luck out!

On complete fillup put 1 gallon of bio, and recommended dosage for grey powerservice (white is for winter climate)

They say the cost is paid for in MPG gains, so don't worry about that.

 

so biodiesel strait in my tank or 50/50?

 

5% or less is recommended. I've yet to try it. Soon though.

 

and how about the guys in ontario can they get biodiesel i cant find it

 

whats important is to put SOMETHING in your fuel.
guarantee this, there is not enough lubricity in ULSD for your stanadyne IP or injectors, period.
the tests i have seen called a "scar test" - ULSD had a rating of something like "620", the highest that should be allowed for mechanical pumps is around 590 - or wear (in some amount) will happen.
a whole list of additives were tested to see what would lower the 620 to an acceptable amount.
PS and stanadyne are solvent based. if you think im kinding, open the toolbox on my truck where i keep the bottle, one of the strongest solvents ive found. not really any lubricant in them, you need an oil for that. they clean the OS and anti gel in the winter.
how much oil is enough or too much?
a quart of oil sounds reasonable and a little solvent based PS or stanadyne to keep the OS clean.
bio is an option. you can also buy a supply of it, dump in a gallon or so when needed - i believe it doesnt go stale like petro diesel.

For the most part i dont use anything but the lubricant. I havent noticed power or MPG gains with a few tanks of Amsoil Cetane boost or a few tanks of Power Service. It could be that the diesel I get is already "premium" 45-50 cetane, so it doesnt matter, but the station people never know and its not labeled. If getting 40 cetane then the additive probably is a benefit.

With the high compression, indirect injection, and low fuel amounts I dont think we have any issue burning up our fuel. I never have any smoke. Increasing Cetane just makes it easier to combust fuel (like what our precombustion is for) so you get better combustion, sort of opposite of octane which makes it harder to detonate.

 

I read a study about 2 months ago and it was shocking to see how some diesel fuel conditoner actually decreased the lubricty of the fuel. The shop that I deal with and what the study showed was that the stanadyne lubricty formula was rated real good. there are 2 others that are better but are very expensive. I own a 2002 volvo highway tractor and used howes diesel fuel conditioner always but not anymore after seeing the stats in the study. Google diesel fuel conditioner study or somthing along the line like that,you should find it. Sorry it dont have the link or address

 

here is the test in PDF

 

I noticed that test didn't have transmission fluid in it... I for one will never run that... but my grandfather swears by it in his 6.9 Ford .

 

Is running ATF bad for the environment?

 

I won't run ATF in an electronic 6.5 for fear of it staining the OS. I don't know if it will or not, but I don't want to be the one to find out. Thus, I'm going to just play it safe and not run it.

 

2 stroke

I am on my third tank using 2 stroke oil. About a quart per fill works out to have been 1oz per gallon. Even the wife noticed it was running a little quieter. I know when my brother runs his 7.3 power stroke with veggie oil its almost as quiet as a Lexus gasser. The down side is it smells like pork fried rice.

That's what i use in my truck. 1 qt of 2-stroke oil to a fillup.

 

No one ever told me about this. I'll start using 2 stroke in my fuel now.

 

power Service Diesel Kleen in the white bottle for winter and the gray bottle for the rest of the year works well too.

The gray bottle stuff helps my mileage as well.

 

Heavy duty vs Non-detergent

Does it have to be non detergent sae30? I cant find non detergent at any of my local parts store but they all have sae30 heavy duty. What would happen if I used an oil with detergent?

 

This thread is 13 years old. I doubt you will get an answer.
Most these days use a quality additive like Stanadyne,, Power Service, Ect. At manufactures stated mix.
Many use TCW3 Marine 2 stroke oil at 1/2 oz per gallon of fuel. It works well to lube the pump and injectors.
I use TCW3 in the summer and white bottle Power service in winter for anti gel and extra cetane to help winter blend fuel.

 

Optilube XPD has served me well over the years.

 

I’ve never used the optilube but basically just stanadyne performance or the purple label lubricity additive they sell.Power service to me seems identical to the stanadyne additive.Same Color and odour the last time I used it.

Maybe it’s the same thing but just in different bottles perhaps.Stanadyne I’m pretty sure doesn’t manufacture it’s own fuel additives but then again anything is possible.

 

i read through this old post, and with my new (rebuilt) IP and optimizer, i want to put my best foot forward. is 2 stroke oil still a good option? or should i seek out a bunch of the stanadyne fluid? since im running a DB2 i dont care about the OS. What about the hotshots LX4 stuff? i used to use their anti-stiction stuff in my 7.3 powerstroke and it did wonders.

 

The Walmart brand TC W3 Two Stroke Oil provides the basic lubricity needed to keep the IP happy

There is an old thread on fuel additives you can read to help you choose something other than 2 stroke oil

Nick has asked that I bring the discussion to a new thread. This way the original thread and report can be permanantly archived in the Sticky's. So, carry on! Same discussion under a new title! SPICER

I think many, maybe all? states in the USA are mandating at least 5%, some states are 20%. Just to make it more interesting there are several states that don't have any requirement to label that at the pump and others where they just say something like 'may contain up to' sort of thing. Same thing with Ethanol in gas. Luckily its been a thing for long enough now in many areas that they got the blending process down pretty well, in the early days they had a lot of issues getting the right blends to the stations and keeping most of the water out.

 

Well, luckily here in Denmark they label it at the pump. Same at all Gas stations across Denmark. B7 for Diesel (Bio Diesel 7%) and E10 for Gas (Ethanol 10%) allthough many Gas stations also offers E5 Gas (good for us who own a Classic Bike that don't ike E10)
