Not only not needed, but could cause problems with injectors etc. Don't add junk to your fuel. Your Cummins likes clean fuel.

I have been doing it the last 30000 miles o problems and i gained a solid 1 mpg . Its not gonna screw up your truck all trucks respond different to different things my advice is try it a couple fill ups and see how it works for you . I put .5 oz of walmart brand twc-3 marine two stroke oil ,a gallon is $11.00 I keep a full 16oz in door pocket .

16 ounces per 25 gallons is about the most I use on my 06. Experiment ,but that seems work best on mine. I have always kept detailed mileage and do see about a one half mile per gallon gain. Also a little quieter. Varies from truck to truck but works for me

I agree with rprice704 about trying it out. Assuming you use the correct oil in the correct amount, you're not likely to screw something up. In all of the research I did before trying it out, I didn't find anyone that had any significant adverse effects from using 2-stroke oil.

My experience is that it has done nothing for my truck. I have been using it in conjunction with PS Diesel Kleen for about 2 months, but have experienced a slight drop in mpg so I plan on stopping for awhile. When the weather is warmer, I'll try it out again for a couple months.

There are benefits to using it even though it may cost you an mpg and thats to lubricate the lift pump and make your injectors a little happier. Some 3rd Gens like it, some love it, some don't really seem to care, and a few don't exactly run well with it.

I did it on a trip I took about 800 mile round trip I don't knoe if it was just dumb luck of dirty fuel or if the oil didnt break down good enough but I was only adding 4 onces per tank and my filter gummed up and truck would hardly run after the second tank so haven't tried it since

It just makes since to me ulsd does not have lubricants like the old diesel that our trucks were designed for.

Cant say for sure, but seems like the Walmart oil does help mine. Didn't start adding anything until this last fall at about 100k after I had some injector issues. I have tried PS Diesel Kleen, Howes, Walmart 2 Stroke, and Optilube. Have not had injector or filter issues when running a lube about 12k miles. May be a little smoother and quiet idling. Optilube among other lubes were involved in a test you can search for. I know I have added a link a couple times on this forum. Bottom line, I will run some kind of lube on a regular basis from now on.
