Yes they do have different tanks for different grades of gasoline. An engine that is designed to run on premium will self destruct in a short time if it is fed regular gasoline. Some engines computer will reset the timing to where it won't self destruct but at a big cut in performance. An engine that is designed for regular grade of gasoline will do fine on premium but it would be a waste of money buying the premium gas as it won't be utilized by the engine.
The grade of gasoline is pretty much determined by the compression ratio of the engine. The higher the compression ratio the higher the octane in the fuel has to be. High octane being premium.

Oh and the trucks that deliver the fuel has more than one chamber to put the different grades of gasoline in and if you'll watch them when the fill the inground tank you will see at some point that the driver of the truck will move the filler hose to another outlet on the truck as he switches to a different in ground tank for the premium grade of fuel.

No way because fuel has to be inspected before it is sold. You can't add anything to it and then LiberalLoner Oct 2012 #26
