i would not say a diesel is any better than a gasser in this respect, personally. does someone have facts on that?

actually the condensation doesn't have anything to do with the fuel or the combustion process (as far as i know). it is i believe just like the condensation you get on your windows in the winter and on your coolaid glass in the summer. humid air condensing moisture on a cooler object. in this case the warm engine has moist air inside which condenses on the cooler block due to the outside temp making the block cooler than the "dew point".

now some of that moisture in the air inside the engine might come from the combustion process, i really don't know about that.
