Hi just thought i would chime in on this too...I have been running veggie oil in my 1995 Ford powerstroke for four years now been using a greasecar kit runs great, saving fuel, yada yada yada. so here are some other things to think about.........i have found and tell people that "think" they want to do this its a commitment! you will spend some dough on pumps, totes, heaters, filters, rags, gloves, speedy dry, cleaners, and of course your kit, im sure there is more lol!! its as messy as you want to make it! and you need a place to do it store it and you don't care if it gets messy , I don't care how careful you are you will make a mess!! I will put money on it every time!! yes I have done it too. now as far as running it in these trucks... heat!!! you have got to get this oil hot so it burns cleanly!!! and do not run it in hopped up "hot" motors let a stock truck burn it cleanly or it will build up in the motor and hurt it. i could go on and on with this...i don't know how hot these motors will get someone else im sure can answer it, I put a 205 deg thermostat in my ford to make sure its nice and hot!! I had a centrifuge still do I found letting the oil set works just as good four to five months minimum . the 275 gallon totes work awesome!! i also bought a 12x24 shed to do this all in i should take some pics lol..........
