"That is certainly your own problem for getting a job so far from home"

Well when we GOT this business it was as payment for a debt. So it was not quite as simple as a "choice" and second gas was 90cents a gallon. Third its a limited license family business. If I stop going there the family hurts and this will eventually hurt me.

Thats why I want to use Waste Oil. I can get enough of it for several YEARS worth of usage and IT IS in fact "my problem" hence why I want to solve it.

Moving work is not possible. Moving home would cost 10times what a lifetime of fuel would cost so thats not an option. (we partially own NOT rent so its not so easy to just "move")

So I have to find a solution around the problem. There are NO alternatives. You are wrong. Period. An alternative is a solution that will cost less money than the current method.

I AM HOPING to "create" a solution with waste oil. but I also can not afford to blow up an engine :-)

SO what components are at risk from whatever is in the oil? How hard is it to replace those components (I have a whole second car so I do not have to BUY any of these components)

Would love any suggestions on how I can test this.
