So....I am in the midst of correcting all the mistakes the PO made with my car when he installed the WVO system. It is currently a 2 tank system with in-tank coil, FPHE, and a heated WVO filter. He plumbed the oil heating system all wrong and this has been quite a learning experience to say the least. The upside is everything I need to run the car on grease is there, I just need to sort out all the bugs.

So, my question. There has been WVO in the main tank of the car for 6 months. It has not been treated with any sort of algaecide or other sort of muck preventing stuff. It has a faint smell of varnish, similar to RUG that has been left in a fuel tank for 20 years. Can I use this oil after filtering and settling or should I get rid of it.

Thanks!
