Can I "turn off" the supercharger on my 1997 Buick Riviera
I have the '97 model, super-charged. However, it requires 91 octane. But, all
the local stations have only 93 premium. Now, with the middle east tension,
premium is about $2.65.
Regular is 88 octane. If I can't turn off the sc, could I run it with 88?
