but burning higher octane than the engine is designed for will leave lots of carbon deposits in the cylinder passages. so they NEED to put more detergent in there so the schmucks who get taken by the "87 octane good, 93 octane better" argument don't spread stories in a couple months about how Stinkmaster SuperPremiumWithBleach turned their car into a limping dog that cost $300 to fix.

What are "cylinder passages"?

the 99+ corolla has 10:1 compression ratio. I think toyota still recommends 87 octane though.
