Toyota Corolla, Engine

has the highest detergent quality of most any fluid/lubrication. The easist way to use it is to disconnect a vacuum line, insert it in the bottle of tranny fluid, and let it suck it into the intake. The trans fluid burns and cooks the crud off of everything -
It will trash the spark plugs that are in the engine now, so get a fresh set for after the cleaning process. Also, have a buddy or significant other manipulate the throttle - your engine doesn't like burning trans fluid and it'll smoke like crazy and try to die.
Revenge tip #1 - aim your car's exhaust towards the neighbor you don't like.

These 2 brands of high-octane advertise thier higher detergencies, compared to 87- and 89-octane grades ("drive your engine clean."). So, is this higher level of detergency, in fact, made necessary because of the fact higher octane levels cause deposits? The advertising makes it sound like the detergents are a bonus (or "plus") that you get for buying high-test!

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.
