-It's not that it loses power when it's cold. If you idle a cold diesel engine you varnish the cylinder walls. Tell your neighbor to read his owners manual and it should tell him not to do it. Even the new gasoline powered cars now say the same thing in the owners manual so I'm told.

A "guy" didn't tell me about the content of diesel fumes. I read a lab report on the makeup of pollution from gas engines versus diesel fumes. I'll try to relocate it and forward it to you. It was 2 or 3 months ago I read it.

Incidently, there are already diesel powered vehicles on the road running on used cooking oil, etc.

The benefits of a diesel engine versus gas in my opinion far outweigh the 'odor' factor. Much longer engine life, very high engine torque, and fuel economy are why I have one. And oh yea, I full time in an RV so I'm usually pulling a heavy load. Doing that with a gasoline engine is rediculous.

Yeah, so I wonder why I often see diesel vehicles sitting around idling. Is there some kind of rumor going around among diesel owners that that's the thing to do?
