How is this John Deere premium diesel fuel conditioner? I use it in my 98 6.5 surburban...but it's expensive as hell.. and I don't know if it does any good, thinking on 2 cycle oil now...great info on here guys.

 

I've been adding 32oz to about 32 gallons every time

 

i just recently started adding the 2 stroke to my 01 cummins. it definatley quietes it down and seems to run smoother. i have ran powerservice for a while before that and am more pleased with the 2 stroke.

 

I used the Wally mart brand 2cycle oil on my 02 F350 Powerstroke. I did it for about 3 months and I developed leaks in all of my High Pressure oil pump O rings. The 7.3's are notorious for delveloping leaks there. I dont know if my truck was due for the leak ( at time of leak I had 127,000 miles) or if it was due from the 2cycle oil I was adding to my tank.
I now have '07 cummins 6.7 and looking to improve my mpg's but I think I will stay away from adding the 2cycle oil. I have talked to numerous diesel mechanics and they insist that the 2cycle oil is not necessary for lub'n up. A standard purchase of additive every 3-5 thousand miles will work with any newer model diesel be it Cummins/PS/Duramax will add needed lubricity.

 

Here's a little light reading for ya.

 

I'll add one from the KING's of fuel injection... (Bosch)

Even Bosch points out the American Diesel fuel back in 2002 didn't meet or exceed the requirements for lubricity for there fuel systems...

 

Like I said earlier in this thread, I've been running 2 stroke oil in my 04.5 Cummins (with the kitty) now for about 75,000 miles with no ill effects. Currently I'm running at a 1/2oz per 1 gallon diesel ratio. Mopar1973Man can vouch for that. At those ratios in my truck that works out to about a 256:1 ratio of diesel fuel:2 stroke oil...............If any of y'all have 2 stroke yard tools/chain saws etc., you'll realize that this is a pretty thin mixture of fuel. My outboard Evinrude on my boat calls for a 50:1 ratio of gas:2 stroke oil................my chain saw and weedwacker call for a 40:1 ratio. So I hope y'all can see the ratios we're running are real thin. Even the 2nd gens which Mopar1973Man has done all research on running at 128:1 is still real thin IMHO.

 

Yea... My VP44 is still singin' down the highway pulling 20-22 MPG and no P0216 code. I've got 99K miles on it with over 3 years of 2 cycle oil diet and no problems to report.

I sit here and shake my head to all the VP44 threads where P0216 pops up and the VP44 is wasted due to poor lift pump or just poor fuel quality.

 

i started add 2 cycle oil to mine within last 2 months and i have to say im a believer mileage went up and runs smoother and quieter.
