Vegetable Oil Conversion of an 85 Mercedes

The original diesel engine designed by Rudolph Diesel was made to run on peanut oil, so it seems natural that the engines can run on vegetable oil. The oil is either new from the store, or used from restaurants or other sources of waste vegetable oil. If used, the oil is filtered and the waste products removed before it’s used in the vehicle.

In the vehicle, the oil must be heated to a certain temperature before it can be used by the injectors. Most of the time, the oil is heated by using the coolant and running it through hoses throughout the vehicle. Many vehicles also have seperate fuel tanks for the veggie oil and regular diesel.

The actual conversion isn’t that difficult, but it’s the fine tuning that I have heard many people complain about.
