I am posting this sticky thread for people who are using Used Cooking Oil (WVO) in Common Rail Diesel engines.
Please record the make, model and year of the vehicle, the mileage before starting to use veggie oil, the date using veggie started, the ration of veggie to diesel or other fuel, the mileage since using veggie oil, any modifications to the vehicle or engine management system (eg Grease Energy ECU remap, DPF bypass, etc).

We look forward to reading your contributions:
