I never owned a car that would "Lose performance with lower octane fuels."
It'll run fine but you're more then likely not running at 100% performance. The engine retards timing to counteract knocking caused by using low octane fuel in a high compression ratio engine. You'll probably never really notice it unless you're really in tune with your car but it is still happening.niteslider said:We loaded regular in my friends sol and it runs fine
:agree: Same with my Benz. Ol' Mercy did like to drink the good stuff, God rest her soul. I think the difference in cost (annualized at about $106 for me) will be well worth it for maximum enjoyment of my Sky. Given my propensity for breaking things, particularly automobiles, the peace of mind I get from following the manufacterer's recommendations in every way is pretty substantial too.vstar said:Had to use high octane in my lexus, got used to it.
