Two friends and I want to get away from paying the high diesel prices. I just saw on the news that fuel will be about $3.00 per gallon in a couple months. Currently it's around $2.86.

The three of us are willing to go in together on some sort of system. But none of us know what we should do. I have a 99.5 psd and they both have a 96' Cummin's. And one 68' Kenworth with a Cat. We want something that is hands down safe for all of our rigs. I have been reading some on the different set up's, but don't have any idea on what is going to work for us.

I like the idea of collecting the used fry oil. Is it as simple as filtering it, installing a seperate tank and them warming it up before it is pumped to the motor?

Will this damage the injectors etc? I seem to read alot about people doing it then others will "refine" it themselves to make bio. Why do this if running strait fry oil is ok? Just so they don't need a second tank?
