Look at this guy, loving himself

As long as your balls don't touch, or so I've been told.

No they won't, unless they're built with a gasoline based engine, which almost no one orders, because the mileage to fuel ratio, cost, and power are terrible for OTR hauls.

Diesels will run on lots of less refined oils using only the heat of compression, like kerosene and fuel oil, as well as being able to run on their own oil (diesel runaway). However CNG, Propane, Gasoline, and other commonly sparked fuels will, in very short order, catastrophically destroy your diesel engine because they detonate at much lower compression than diesels require.

Furthermore, you'd ruin your high pressure fuel pump as gasoline doesn't have the required lubricity. The injectors would probably be fine, but your pump and your cylinders/pistons/crank/rods/mains would be having extremely bad days.

I mean, it will run on gas once...

Make sure to make a video.

If you can also write an article, you can call it 'science'

Old mechanical injection diesels use the same principles of physics as the new ones do, just with electronic timing and fuel injection. I mean, the engine may on this stuff at least once. For some length of time. You can also do pretty much anything at least once. It's the consequences that are the issue. You're just doing the damage slower by diluting the fuel that doesn't belong.
