Good morning I was wondering what you guys/gals add to your diesel fuel for your injectors, and motor lubrication. I have heard a couple guys say they add a quart of atf fluid to the tank when filling, but I also had a shop try selling an 8oz bottle for 35$ that he recommended for the motor.

Seems pretty expensive to me but thought I would ask here first.

 

16 ounces of Power Service "Diesel Kleen".

You can buy 5 tanks worth at Walmart for like $10-15

 

X2 for diesel kleen from walmart....

 

I have a 1996 2500 2wd with 356,000 mi. I have always used Marvel Mystery Oil. Cummins has never had a bolt cracked on any major internal issues. I just use it as instructed on the bottle. Why do I use it, easy, my Dad swore by it for years. I have added some info from marvel website. And no I am not employed by Marvel in any way. My Dad started using this product in the 1930's. I am 63 yrs young now and use it in all my vehicles.


Can I use Marvel Mystery Oil® with diesel fuel and if so, how much do I use?


Yes, you can use MMO in diesel fuel as well as gasoline. Use the same amounts as the gasoline treatment recommendations-4ozs of MMO for every 10 gallons of fuel. However, MMO does not comply with federal low sulfur content requirements for use in model year 2007 and newer diesel motor vehicles.

How much MMO do I add to the crankcase?
Marvel recommends replacing between 10 and 25 percent of your motor oil with MMO. For example, if the crankcase capacity is 5-quarts, add 4 quarts of your favorite motor oil and one quart of Marvel Mystery Oil. If you get your oil changed at a “quick-lube” facility, bring a quart of Marvel with you and ask them to add it to your engine in lieu of one quart of traditional motor oil.

Can MMO be used with synthetic motor oils?
Yes, MMO is compatible with synthetic, semi-synthetic blends and regular types of motor oils.

Can I use MMO to replace all of my regular engine oil?
No, you cannot use MMO to replace all the oil in the crankcase. The maximum amount of MMO to be used is 25% of crankcase capacity.

 

wally world 2 stroke oil. helps keep my injection pump lubricated. only reason I use it...engine itself doesn't need it. a Cummins will run over a million miles without additives. especially a p7100 12v motor or a p7100 converted 24v motor.

CR motors have injector cracking problems that can easily lead to piston failure so I would keep a close eye on your rail pressures.

 

Same here. Do not want to replace a VP44 injection pump and a little 2 stroke goes a long way. Quiets the engine down also.

 

STANADYNE one of the best did alot of research on this

 

Stanadyne, RevX, Diesel Kleen, whatever I can get my hands on.

ATF is high detergent, good for cleaning out the injectors and whatnot.

A guy I worked with runs about 45% used ATF (dual filtered 10/2 micron before going into his tank) 5% unleaded, and 50% diesel. Worked well for him.

 

Thank you all for the responses, going to different additives each time I fill up.

 

Don't forget oil additives.
