Techron: Yes it is superior to other gas detergents. I pretty sure there is a thread from way back if you do a search. You can always just buy the additive in a auto parts store and add it to your gas twice a year. Chevron has a patent on polyether amines which is why other oil companies can not offer the same additive in their fuel.

Lower grade gas: Read your manual. Most, if not all modern cars sense knock long before the point where it would do any damage to your engine. My 94 BMW recommends high octane fuel but allows low octane fuel with the only caveat that performance/effeciency may be less. No warranty issues despite some unsupported assertions in this thread.

And BTW, the temperature of the intake air definitely will affect detonation (as well as effeciency).
