I have been driving a 1985 300sd for 3 years now and blending vegatable oil. I bought the car because people said that mid 80s cars were tough and they made a believer out of me. I have been looking for a nicer car for my wife and have found that I can buy a 1997 or 1998 300d for about the same price as a 1984 or 1985 300d. Can someone tell me the difference? Am I making a mistake even thinking about running vegatable oil in the newer models? I have put over 75000 miles on the 1985 blending vegatable oil with kero, gas, and diesel kleen. Comments and suggestions welcome. Thanks Jack
