PREMIUM GAS

RE: PREMIUM GAS
This is what I have heard: If your car manufacturer recommends 91 octane, you can still put in 87 octane gas, and it won't hurt the car. The onboard computer will compensate the timing and the engine won't knock. The only "adverse" affect to filling up with regular gas, instead of premium, is that you won't make all the power that your can with premium gas.
For my Vette, it's only premium gas. For the 'Lade, I've never tried regular gas, but it's just because I'm so accustom to pushing that "premium" button....they've got me programmed....

THANKS FOR THE INFO, BUT MAYBE I SHOULD HAVE SAID THAT I AM TALKING ABOUT A 95 SEVILLE SLS WITH 100K MILES. I HAVE ALWAYS USED PREMIUM AS SPECIFIED. I LOVE THE VEHICLE AND DON'T WANT TO HURT IT BY USING A LESSER OCTANE FUEL...JUST THOUGHT I COULD SAVE A BUCK OR TWO UNTIL GAS PRICES COME DOWN AGAIN AT THE END OF THE SUMMER. ( IF THAT HAPPENS )

"Premium Required" at the fuel gauge isn't there for nothing. Add older car with low miles that you "love" and have always used premium tells me that you should continue.

"Premium recommended" you can use a lower octane with no damage to the engine and the knock sensor should take care of the rest.
