Should I Run 2 Cycle Oil In My Fuel?
 

I have just recently heard that some people are running 2 stroke oil in there diesel. They say it increases MPG, horsepower, better lubricates entire fuel system, and quiets motor. What do you know? Should I start running it? Thanks!:humm:

i'm sure it's not even noticable but yea i've read it increased 1mpg in diesel power, but common rail injection is not as tolerant as older systems. so i'd do more research

run it in my 6.7 does just fine 2 cycle oil breaks down when mixed i just run like a quart to a full tank every other tank or couple tanks hasnt hurt mine its just lube:tu:

Thanks. What brand are you using? Have you heard of any people running it in there 5.9s?:tu:

Run it in my '06 5.9 ..... I use a pint on fill up so it mixes with the fuel.

I've noticed it really does quiet the engine, and a slight improvement in mileage but I think that might be due to the cetane booster I use as well.

one ounce per gallon is the best ratio any brand will work walmart has it by the gallon!

Is your diesel a 2 stroke????

(the only real reasoning of running it is lube the junk fuel we got anymore) and for the brand any brand will work for what your wanting it to do like said above hit up walmart get u a gallon or so and ya some of the 5.9 guys are running it in theres also the fueling systems are the same i think for the most part

I read on another post that you need to add 2% of 2 stroke oil in your fuel ( example, for 100L of fuel you add 2L of oil) This is not cheap, a gallon of 2 stroke oil is around 15$. I had DELPHI additive in my fuel, it's good to lubricate the pump, prevent water and clean the injector and get better mileage. It cost around 8$ and it's good for 500L of fuel, it's make by a diesel parts company for diesel engine, 2 stroke oil is made for 2 stroke engine and the only think it do it's lubricate the pump and build up dirt in your engine....... Have a good day!

I was adding Stanadyne Performance then was told to run Marval Mystery Oil when I took it to the dealership under warranty when it kept white smoking and missing. I didn't when I saw this (I use 2-stroke oil as of now).

I haven't noticed any difference in MPG, power, etc., though- I always thought it would just lube it up a little better.
