I know of a few trucking companies (long since out of business) that dumped waste engine oil into their fuel tanks.  Their mechanics all told me that is caused the injectors to wear faster.  Apparently, the grit in the oil is the problem.  Your engine oil filter cannot filter everything out.  Personally, I wouldn't do it but it is your choice.
