I live in North Florida and don't see very cold temps here and if we get down to 30 or so, it does not last long. Thinking of Bio-diesel or even a WVO conversion on my truck.
1) WVO, can it harm the motor? I am looking for 400,000 mile plus out of it.

2)Is there any loss in performance. I have some mods both for fun and I tow a 22,000lb trailer at least once a week now.

3) I use this truck for work that is about 65 to even 100 miles a day for work depending which job I have for the day.
What is the best motor for a WVO conversion?
