i was told that if i pour a pint of 2 stroke motor oil in my gas tank when i fill it up it will give me better fuel milage. anyone done this or heard of it?

Makes my injector balance rates better, increases lubrication for the injectors, and makes the motor run quieter. Never noticed any gains in mileage though.

I used to pour in a little power steering fluid when I wanted to lay the smoke extra thick :D never noticed a difference in the fuel mileage though.

A lot of us are adding 2 stroke oil to our DIESEL fuel to increase lubricity lost with the change to ULSD (ultra low sulfur diesel). I add 1/2 ounce per gallon of fuel (12 ounces in a 24 gallon fillup of my 26 gallon tank). It does not affect mileage in any measurable way, but will quiet down the engine, smooth idle and makes mine feel "peppier". You don't have a signature, but I assume you have a DuraMax or 6.2/6.5TD and not a truck with a gas engine. I would NOT recommend adding 2 stroke oil to the fuel tank on a gasoline engine.

I have ran 5 gallons of premix through my blazer with half a tank of regular fuel(9 gallons) without any problems.

Look around and see if you can find the Blue Marble 2 stroke oil and give it a try.

For us Candians 1/2 OZ = 14 ml.. so for every Liter of diesel we add 14 ml of 2 stroke oil.. our formula for caculating how much oil to add would be your number of liters Times By 3.8 will give you how much oil to add..
The number 14 comes from how many ml per liter and the number 3.8 is a rough number for one gallon converted to liters... for exaple
20 Liters X 3.8 =76 ml of oil to add..

Every few months my uncle will add half quart of transmission fluid to his gas truck. This helps keep injectors clean too. Hes a big rig diesel mechanic with many years experience. I'm not sure if he does it to diesel engines but I'll try to find out.

Id go read more about this before continuing .

This was heavily discussed in here a few years ago and most stopped doing this .

To each thier own , but I dont add oil or 2 stroke to my fuel at all . Just injector cleaners once in a while .

Try going and doing a search on this and read about it as much as possible .

Beware !! , just because guys are doing it with no problems doesnt mean it's good . If I recall many guys were having high injector balance #'s after doing this for a while .

Cant remember exactly , I just do the normal things .

There were many threads on this , I thought reputable guys that did some extensive testing on this were not recommending this .

And now I keep seeing some threads on this popping up again .

Maybe now that it has been a few years , there will be a few that chime in that have long periods doing this with no problems . And exactly what products to use or dont use .

I never advocate anyone ever doing what I do just because I do it. It's up to each owner to do what they think best for their truck. There was a lot of back and forth on the issue and many had strong opinions either way. There was only ONE person that I'm aware of that experienced a problem with increasing balance rates, that was Bodysurfer, and he stopped as is his perogative. There are MANY of us who had good results and are continuing to have good results. I'm running it on every fill and have good balance rates at 157,000 miles on my original 2001 injectors. That doesn't mean that someone shouldn't do what they feel is best for their truck or what they are comfortable with trying. Just to clear the air on the apparent success or failure rate - it is HEAVILY in favor of benefit or no harm for long term use - not what you indicated in your post, Gasout.

ATF is an "old school" diesel mechanic's trick for mechanically injected engines (OTR big rig engines and heavy equipment) that run at much lower injection pressures (2000 psig or less) with very simple injectors that basically just pop against pressure at one stroke per cylinder firing. ATF contains a lot of stuff that I wouldn't want to run in a High Pressure Common Rail modern injection system that runs at 10 to 20,000 psig with electically-fired injectors relying on multiple stroke times in the milliseconds per cylinder. 2-stroke oil is oil designed to blend with fuel and be combusted, ATF is designed to resist combustion and contains anti-foaming and a lot of other chemicals. There is no "hard science" associated with 2-stroke use to increase the lubricity of Ultra Low Sulfur Diesel, but it's a lot less "off the reservation" than using ATF. Some say use nothing. Some say use a fuel additive that is formulated for diesel only. I've been successful in my truck using an additive for a long time. When they went to ULSD and I got concerned about the loss of lubricity, I started adding 2-stroke oil AND continued using an additive. Your truck and your choice what you do with it - I wouldn't use ATF and I wouldn't recommend it for a modern truck.

Well I guess the reason why is bodysurfer is a good friend of mine and I was a little tainted by his results . When it come to running something through your injectors it shouldnt be taken lightly .

I also wanted to try this and see how I felt on my own results , but refrained after Bodysurfer saw a raise in balance rates . And others thoughts on this .

I wasnt trying to taint anybody from doing this , it was just a beware .

If you go back a few years Bodysurfer was doing a test on all fuel additives and posting on a daily basis . Also I talked to many diesel techs on the same issue and also was told they didnt think it was a good idea .

They told me that 2 stroke doesnt mix with diesel fuel like it does with gasoline .

Im very happy to hear that you have not had any problems running this and glad you chimed in .

Just remember I am just putting out the read all the info posted out there in the past before just pouring this stuff into your tank . I think it is also important to remember that there are many types of 2 stroke with different properties .

Did you post anything about that or what you specifically run and dont run . What properties some have and dont have . Dont jump back at me because I think guys should read and be more aware before just pouring stuff into the tank . It was trying to be helpful not a dont do this .

I went and did some research myself on this because I wanted to try it and couldnt get any good responces to doing so by many different mechanics in the diesel field . We do not have old style injectors or pumps like other diesels use to . I was told it would be fine in old school injector systems but beware in our new trucks .

My post is just the same as the old arguement .

Think about it scientifically . And the many different properties in different types of 2 stroke . Bean , synthetic , petroleum .......

This was just a post to bring up that this was heavily discussed a few years ago . And Im really glad to see you have been doing and seen good results from this , or let me state no poor results . Because you could have possibly had good results just running #2 . The fact that you havnt had bad results really proves nothing , but looks good too . I have run #2 only and have had no issues with injectors like others . Ive replaced a few injector just because I could before my warranty was up . I replaced 3 of my highest balance injectors for the hell of it . When I cracked a piston a few monthes back it was most likely from the high egt's and huge tunes I run . ( 530 rwhp with 2 CP3's ) But it was up in the air due to hole in piston if I stuck an injector . Will never really know . I think I did it from HP and high egt's . So do many others . I held my truck at 2000 degs for long periods of times climbing big sand mountains in the sand dunes at Glamis Dunes .

I'll tell you that last tank of fuel I put in was low sulphur and I even thought about this at the pump . Low lubricity in fuel .


I think it is important that someone post the properties in different oils and the do's and dont's of different oils and what from a science point of view would be best . Some guys that are a little green should have all the info .

Even Im green on this and wish I new more on what is best .

Im still interested in this and not completely against it , but you were here back then and remember the length of the threads on this .

I thought posting a read before running was a fair statement to those not privi to previous threads years back . There was more guys posting on this from a scientific point of view other than just Bodysurfers testing of all additives .

Just trying to be complete , and also interested in this myself with the new fuel we've been stuck running .

Once again very happy to see you have had great results and it just makes me want to know more about what oil is best to run . From a chemical breakdown on properties in oil and why to run one over another .

Now after years of someone doing it it is good to see results over long period use . Some guys Ive read are putting motor oil in also .

This subject kinda died out and glad to see it being discussed again .

Stanadyne makes a lubricity product. Does anyone know what it is made of? I'm not talking about the Proformance Formula. Maybe that is the best lube to add to the fuel if someone is concerned using the ultra low fuel?
I personally don't know, but it seems logical.
Pros vs Cons?

Just looked at a bottle of Power Service and it says they add "slick diesel" for lubrication.
What is that? Their own sales gimmick, or an actual product that is added?

I try to use 5% bio every chance I can. It will help quiet down the engine and cranks the lubricity up to pre ULSD levels.

My $.02 worth...

Not trying to flame you, Gasout - you are a "leader" in pushing the envelope on your truck and I respect and admire your experience and contributions. I was trying to "balance" the information with my own experience and not take you to task. Bodysurfer put a lot of time and effort into additives before Spicer did the blind test and I'm not discounting his experience or denegrating his opinion, either. You did have a bit of a negative bias on the situation, as I have a postive one with my personal experience. I just felt it was important to point out that "many" have not experienced increasing balance rates and in actuality (not confirmed by actual polls or research) "many" have experienced positive or no problem results with 2-stroke.

You and I both agree that the individual owner should do his homework and make the choices that he is most comfortable with. It's all good and I apologize if I seemed to have jumped you on the topic - just offering "equal time." Hope you have a safe and happy holiday weekend!

I had my factory '02 injectors changed at 193k miles. I did run 2 stroke oil for awhile before I changed my injectors. It may have been coincident, but my injectors seemed to go downhill pretty quick once I started using the 2 stroke oil.

There is nothing scientific about this statement and it may have been just a pure coincident, but I'm not going to use the 2 stroke w/ the new injectors.

I found the 5% bio quiets down the engine as much as the 2 stroke. I'm fortunate there are 2 truckstops within 8 miles of my home that sells 5%

Idle chatter ..... no offence taken we are on the same page .

I too have been so curious about running something to help .

Stanadyne , Lucas , and Shaeffer winterizer is what I have run and not very often either . Only in the past when i had some funny clattering injectors from what I thought to be bad fuel that maybe had some gasoline dumped in the wrong tank at a station . In later years being around a few trucks that had gasoline accidentally put in them that sounded similar I came to this conclusion .

I just wish there was something made especially and specifically for helping lubricate out injectors with this new fuel . It has been on my mind alot and Im going to start running probably stanadyne on a regular basis in the future here when I get motor back in truck in a few weeks .

Sorry if I came off like I was offended . It's all good . We are 2 guys that have chosen different routes on a situation . You actually had more balls to try this than I .

And until I have proven facts on it wont run it .

All is good my friend ,and glad to hear after many years you have had great success with this .

Not to bring it all up again, but the Splicer test was very informative and has open many eyes, also mine. I have still continued to search for the best product and/or mix. I've been running a mix for sometime now. Don't look for a additive to give you +mpg but think of them to assist in cleaning/lubing/etc for the fuel system. Each person will have different experiences with different products... each engine acts differentlly... its a mechanical device and many other factors play into it (ie. weather (cold/warm climates), etc.). Also, I think Johnny threw out my name only because we go way back as friends and if I am correct, I think we became "great" friends because this subject matter was interesting/important to him... Johnny, correct me if I am wrong.

Basically, if one feels/notices that product "X" works for their engine, then use it. I have always been open minded about every product. That is why years back (pre-Splicer's test), I tried many additives. I still and will continue to use my mix in every fill up.

Doug.

Thanks guys - I try to contribute experience when I can (and opinion a lot too, unfortunately) and I know that both of you do too. Me brave? I think I'm pretty milktoast compared to what you do with that Kodiak, Gasout! It's all good.

BodySurfer tell us more about what your running now . And what were your experiences with 2 stroke were and what and how long you tested different things . Just refresh me a little on it again . Its been a while .

Thanks
