I have over 5 years in using Vegetable Oil for fuel. I am currently looking for someone to pickup from restaurants and I will centrifuge/filter the oil. We split the oil collected 50/50. Centrifuging is the most reliable and Best way to clean the oil for a diesel. Anything less and it risks the damage to the IP. I do not charge anything, just a 50/50 split.

And no mess in your garage. Just drop off the oil and fill up.

Win/Win

Let me know.
