Diesel with cooking oil boost.

I was filling up my (GM diesel truck)tank last night and a new Mercedes is park beside me. I started fueling up and the owner of the Mercedes comments that diesel is still extremely high. I didn't notice he was driving a turbo diesel sports car.

He then told me to check this out, Mind you he has olny put 10 gals of diesel in his vehicle before hand. He opens his trunk and pulls out 10 gals of used cooking oil. He pours the cooking oil into the fuel tank. I had asked him if the car was converted, he replied "no the conversion is about $1500 and I don't need it, I'm mixing a 50/50 ratio to be safe".

The owner tells me that he has been running his car on the fuel mixture for years and has had no problems at all. He then asks me if I want to go pick up some cooking oil at his shop.

Is this method safe to use with out the conversion?????

i wouldn't do it, i've seen off road diesel jack up injectors in dmax's more times than i can count, and i'm the 1 who had to replace them been a gm diesel master tech for the last 8yrs, and screwing with the fuel isn't a good idea at 400 bucks an injector. i have no probs with biodiesel, shit runs good, even have a good bud who makes his own and sets refineries up across the nation.

I was thinking the same thing, but I'm newbie whenit comes to diesel. If theres costly repairs, I want nothing to do with it. Thanks for the info, greatly appreciated.

He can't run 100% veggie because he doesn't have a second heated tank for it. You can run 100 veggie in your truck but you need the right stuff. These guys are at or near the top for proven veggie fuel systems;

Veggie oil is not anywhere close to offroad diesel. In fact it's much better than #2 diesel for your engine.

I have about 5000 miles on my truck with wvo, I built the system from here for the 7.3

Well there's lots of these additives that are floating around in the marketplace, but the diesel forums I'm on they say that TWC3 2-stroke oil works best. However, I was impressed by the testimonials and I might try both the fuel and oil additives. The prices are good and who knows they might actually WORK.

If you're talking about the truck in your sig it's the 24 valve motor.
