I spent half my life working in the labs and offices of the world largest gasoline and oil companies here in Houston, would love to read some facts and not opinions.

Well if you worked half your life in the labs and offices of the gas and oil companies as you claim then you wouldn't be asking for facts; you'd already know. How about you just contact Toyota, you know the people who DESIGNED THE ENGINE and ask them what they meant when they PUT IT IN THE MANUAL? Since you don't seem willing to accept the owner's manual as "facts" it won't matter what I or anyone else on this forum says.

Oh and keep in mind that the gas and oil companies WANT you spending more money on the higher octane fuels so they aren't about to tell you otherwise. Ask people who rebuild engines for a living; who service fuel and ignition systems; who make spark plugs, valves, rings, pistons. Ask the people who deal with the consequences of tens of thousands of miles of fuel usage in engines; they'll give you some "facts".

If you're "sick and tired" then relieve your symptoms by doing some research yourself instead of demanding others do it for you. I stated what I know based on decades of experience with cars. If you don't like it or disagree with it; fine. Everybody is entitled to their opinion. Why don't you just fill your tank with 87; run it out, measure your gas mileage. Then fill up with 92 and see if you can tell any difference other than the cost. If you can't, then there's your "facts". But it's your car; spend your money on whatever grade fuel you want to.
