1999: Switching from Premium to Regular Gas

If it pings heavy under load while using the lower OT gas it is not good for the engine. I would not go lower then 89 give it a test. No need to drain tank just add to whats aready in tank.

You won't hear it ping. It will retard the timing. The question is: will you lose more in mileage than you gain in fuel savings? If it has more than 80K or so, there's a good change your knock sensor is dead and you're wasting money on premium anyway.

If you care for environment and possibility of CANCER for yourself/children, continue using premium gas - less pollution/better milage/better engine protection, yes it costs more and more, well: MAYBE you people should stop hauling heavy nonessential things in your cars, I make 40+mpg precisely because of remving everything possible even spar etire/wheel as I am covered by 3-yea FREE roadside asst. (new car), maybe eat less junk, quit smoking, walk and take trains/subway smore, ok We Americans are called gringos for a reason, too much driving, it make sme sick looking at fat bastards here in Brooklyn driving a few blocks to a supermarket, why not walk, da hell the person loooks like a jelly with a huge belly

what does "gringo" have to do with driving....did i miss something?

first you criticize people for driving too much, and not taking mass transit, then brag about your great mileage?

Not only that, carrying no spare tire means a required visit from the roadside assistance crew in the event of a flat tire. The ones areound here are usually quite large turbo diesel trucks that probably burn more fuel and harm the environment more getting to me than if I sacraficed 50lbs and changed my own tire!
