I (and being one of those Texans you seem to like taking shots at) would rather talk about all the things you can cook in it.

Ok - back to beating on the horse......

Last time I checked, it didn't evaporate when I poured it on the lawn, so yes it needs to treated with thick rubber gloves and a large vat.

That was 240Joe's main argument (I think it's a perfectly valid one), all I'm doing is restating what he's already said.

Yes, everything does come from somewhere, good point. Are you trying to say dino motor oil has some huge impact on the enviroment????

i didn't think there was any oil question that i could be tempted to answer, but here you go.

So far so good. That makes perfect sense.
So why would a diesel say a 603 have less problem with this occouring than a gas say 103?

Diesels are more prone to "igniting" just about anything that runs through it. Not to say it would ignite H2O, but it is easily passed through as a byproduct. Gassers rely on the actual "lighting" of it's fuel.

I don't buy this. The pitch is that it can be run longer than other oil, and thus they may be biased more than slightly the other direction. They have to justify the price.

oh wait...I thought you were asking if it was really wasting "oil" to change it so soon. PAOs are made from ethylene. That was my point.

Mine too.

So... and pardon me if I'm not getting this... the water in the oil (not the fuel) is burned off better by a diesel because a diesel...?

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.
