That's a bit of an understatement. It's the second or third touchiest thing in diesel discussion right after "which engine oil to use" and either just above or just below "R12 vs. alternative refrigerants". There's A LOT of back and forth over the pros and cons of WVO, and I think most of us have come down on the con side. I will concede that veg oil (new or used) can be run successfully, but you have to do everything right every single time, especially in cooler climates. Failure to do so WILL cause expensive damage in a relatively short time.
A better option in my opinion is to home brew biodiesel if you're trying to save money. There are still plenty of ways to screw this up, but I think it's easier for most people to get consistently right than trying to run a veggie conversion.
Best of all from a quality standpoint is to use either petrodiesel, or ASTM-compliant commercially available biodiesel, or a mixture of the two.
