Anyone run any of these additives in their DuraMax's? They seem pretty popular with the Cummins crowd... many guys say 1~3 mpg gains are common

here's a link to dodgeforum where there is a whole thread on them.

i don't see any issue with the power service stuff. IIRC gm officially recommends standadyne but power service is a good choice and more readily available. the marvel mystery oil is another story and i'm not sure how the injectors will like it.:spit: the cummins had mechanical injectors for several years and you can run darn near anything through them without hurting them. some even run filtered waste motor oil. i don't in my cummins and this is a big no-no for the duramax.

gotcha... so the standadyne/power service is to keep the diesel in good cond. and keep it from gelling! Correct???

And oil is a no-no for duramax's... (i've even heard of some cummins guys running two stroke in theirs...)

so what part of that equation helps you get better MPG???

I guess what im wondering is if anyone uses any additives to increase mileage in their duramax's!? or to keep them running good...

i can't officially say marvel mystery oil is bad for the duramax. i'm hoping others will jump in and give their $.02 soon. i can tell you that waste motor oil and 2-stroke oil is a no-no.

any additive that has a cetane boost can has the potential to increase fuel mileage. the power service stuff comes in many different formulas. i run the "diesel kleen with cetane" in my cummins and it's specially formulated for the new ULSD. their "diesel fuel supplement with cetane" has the added anti-gel properties. either of those take typically 16 oz to a tank as one 16 oz bottle treats 35 gal of fuel. i buy it in the 96 oz jug at wal-mart.

the standadyne stuff does work very well. we sell it at my dealership and i can vouch for it's anit-gel properties. check your local dealer as they might carry it as well.

any quality #2 diesel will have anti-gel additives in it during the winter months. and most stations only carry #2. but it doesn't hurt anything to add an anti-gel at the fill up if you want to.

like i said, i don't know all the in's and out's of fuel additives and i'm really hoping others will chime in.

hope what i had to say will help a little.

from my experience...those guy are FOS....I don't know how they figure mileage, but if they aren't filling up to the exact same spot each time it isn't a consistant way to calculate mileage. (you could fill up with a gallon or 2 less depending on how you fill your tank) If you do not actually ride with them...I find anyone's mileage claims hard to believe. I bought a diesel because of all the mileage claims that I have heard from my friends. Well, the mileage isn't bad compaired to my old gas truck, but it is about 5 mpg off of what they claimed. I am happy none the less. Stanadyne does good with anti-gel....I should know....I live in Alaska and use it with almost every tank year round. I have not seen a mileage increase from it though...just piece of mind. I have also used the power service additive when I could not find stanadyne. Worked good, no mileage increase though.

 

[skeeterkilr]

yeah, ob, i have to tend to agree. everyone on another forum i belong to was raving about running 2-stroke in their trucks. increased their mileage and supposedly made the pump and injectors quieter. well i've ran about 9 tanks mixed with half to 1 full quart of 2-stroke and i didn't notice any differences. maybe it's the way fuels are blended for different parts of the country. beats the heck outta me.

I run the power service in the white bottle, its a cetane booster, cleaner and anti gel, dose it work? i dont know but i run it just for peice of mind aginst low sulfer diesel and now ULSD!

 

[brusky1996]

i use pure power it pretty much covers everything but i cant say it helps my mpg

I run the same stuff occasionally even though our fuel at the farm is 60/40 blend.........Doesn't help my mpg at all never did when i had a cummins or dads stroker.

 

[Kawtipping]

I have just started using the Power Service in the gray bottle. I have actually seen a mileage reduction. Perhaps I had a slight clog in an injector that was helping stem fuel flow and saving fuel? Or it could be that at the same time, our weather finally started acting like winter.

 

[Bigblu71]

I have heard of people using a similar mixture of the PS and Auto Trans fluid (they say this is more of a detergent and will clean as well as lube). Personally I have used the PS in the grey bottle and did notice a difference in engine noise, but not much in fuel mileage.

 

[duramaxsandwich]

i use power service in the white and makes me feel better because with some of these places in illinois you never know what you're getting as far as bio diesel mix or anything else for that matter.
