[AT] Canola to diesel

[Tom Yasnowski]

I guess it all depends on what one thinks a "true diesel" really is...To me 
if the fuel, whatever that fule is, can ignite with compression instead of 
spark than I view it as a compression engine. If its bastardized in ways you 
and George describe and you no longer considier it a compression engine, 
then I guess thats your right. But I would bet the EPA  and DOT would call 
my MB a "diesel".
