Dan sez:

" Another off the wall idea is a system that has two gas tanks, one for
regular and one for premium. It would let you have a higher
compression ratio, and still use regular gasolene most of the time.
Just use the premium when you need it."

If your car was set up to run on regular why would you ever need premium in
the same car? Or it you meant the car already had a higher compression
ratio, necessitating premium, what conditions do you visualize that would
need regular?

Okay here is another thought. Would there be any advantage to having a
Ethanol injection system? Especially as a factory installed item. I
would think that Ethanol would provide the same advantages for knock
prevention as the water injection system.
