Thanks for hijacking my thread, Cliffmac.

I was TRYING to get a discussion on ethanol versus mileage and instead we have drifted off into yet another case of you bashing of high-octane fuel.

Not only are most of your assertions incorrect, but they're irresponsible. Luckily there are plenty of people here to point out your folly lest somebody actually take a notion to follow your advice.

Plus, those "things called knock sensors" as you so eloquently put it only appear on newer cars. My '90 300SE doesn't have one, and I doubt the '79 BMW does either. In any case, the result of a detected knock is the computer retarding ignition timing in order to curb the detonation. In order for it to work, you have to make your car detonate first! In other words, all it does is try to stop damage all ready in progress. If that concept makes you happy running low octane fuel, then cheers!

I dare you to DOCUMENT the fuel you've been running and present it when you try to sell the car.

Normally I don't like to go off on other contributers here, but you've stolen my thread and filled it with off-topic disinformation.

If you really like to flame bait, start a thread of your own. Last time I looked it was free.

"MB and BMW and so forth expect you, as the average owner to not put premium in ....."

Right. That's why it says PREMIUM FUEL ONLY on the instrument cluster. You're a genius.
