This tangent seems to be a
Bill G Challenge which you've a solid reputation for, and in an oil thread nonetheless! (It's like the Internet version of opening a portal to hell!)
1. Gasoline and diesel come from the same base product.
Gasoline used to be used to start high-compression diesel engines (2-minute mark shows the gas tank, spark plugs, carburetor, etc., the 7-minute mark shows the diesel engine running on gas). Both gas and diesel are used to run engines, and from that standpoint are substantially similar, to the point both are bio-fuel targets with similar end-goals.
2. That's a distraction so far off the bar oil topic I personally wouldn't go there. There are threads discussing
canola oil jelling up bar oil tanks over time (post #82), if you're interested.
