[edit] Mercedes Conversion

One of the simplest and best cars to convert is a classic late 70s/early 80s Mercedes Diesel. Costing over $40,000 new back in the 80s, these cars were "overbuilt" having numerious backup systems for when the main parts fail. They are also tolerant of the rigors of running vegetable oil due to their robust lift and injection pumps and well built engines. People have successfully run SVO in these cars with no modifications. More common and dependable are dual tank systems that come in a variety of configurations. Many of these cars suffer from abuse and neglect, yet keep on running. To fully restore such a relic would cost a fortune, but catching up on basic maintenance is not so challenging. Many of the maintenance items are easy enough for the novice, especially witht he helpful books and videos out ther.

Pre-conversion maintenance items:

• New Thermostat

• New air filter

• Fuel filter

• Valve Adjustment

-Also, it would be wise to check the compression to gauge engine health before forging ahead with a conversion. An unhealthy engine is not going to like WVO.
