[AT] Canola to diesel

[Tom Yasnowski]

I cant speak for the new MB's, but If the old mercedes are not true diesels 
then today isnt super bowl sunday. If it sounds like a diesel, smells like a 
diesel, takes diesel fuel, has lousy pickup and
starts hard in the cold, has 260K + miles and still purrs, and can run 
straight vegetable oil to boot, and doiesnt have spark plugs,then by gollly, 
its a diesel!.
