Fuel problem

I did some fuel mileage testing on PSwb and lost 1mpg and lost 1.5mpg using PSgb (Power Service grey bottle) on my PSD.

However that wasn't true of PSwb about 15yrs ago as I used it in my VW diesel and there it increased fuel mileage alot, from 36mpg to 52mpg.

I had a old PS container so I comparred and there was a difference so I did some research. About 1999 PS was refromulated for whatever reason and the container size shrunk, 3qts to 1gal.

ATF doesn't loose fuel mileage and is cheap, $1qt and does twice the job as PS for luberication, in fact I couldn't tell any difference in injector noise with PSwb/gb but I sure can with ATF.

Do a small test. Run pure (no additives) #2D for a couple tanks, then add ATF type F at 1qt/100gal then come back and tell me your opinion. I would interested to here it.

Very interesting. Would be hard for me to run a good test, since I was talking about my 2 trators. My old truck is just a gasser.

When are you coming through my area. I am just off I-20 about 30 miles West of Fort Worth, at Weatherford, TX. Maybe you could pull a coffee stop just off the interstate and I could meet you. I have been reading your posts for a long time now, and agree with you on nearly everything, and it would be nice to buy you a dinner and/or coffee. my email is tom-fletcher@att.net

I use ATF type F, 1qt/100gal #2D in my 02 F350 PSD for the past 15k miles. I only have 19k on the truck. It imeaditly quitens the injector noise by half on my PSD.

I could care less what Ford says as it my money and I want 500k plus out of my injectors. If I would take it in for a injector warranty repair, Ford would just tell me the injector damage was caused by water, so no warranty.

I also quad filter my fuel, once at the fuel stop pump, twice at my aux fuel tank, 10micron and 2 micron, then the factory installed final filter. I get sediment in the 10micron filter bowel but not the 2micron filter.

I ran type F in a VW diesel for 300k miles without any problems.
