I run 85 regular...and I've got a supercharger! I don't go WOT too often, but when I do, I don't notice any pinging. And I don't care if she blows--I want to do a rebuild, anyway.

I don't care what John J. Chevron says, in an engine that's pinging like hell on cheap (lower octane) fuel there is a definite need to run higher octane. Octane is, simply put, a measure of a fuel's resistance to predetonation.
If you're getting spark knock or pinging, raising the octane is usually an easy fix.
Since it was brand new my truck has pinged on anything less than 91. Rather than make Toyota rewrite the owners manual, I have just always run premium.
Right now I have other issues that are making it ping even worse, and I am still running premium to offset some of that.
I'm not going to put my timing at 0 degrees to stop the knock and have ants run along beside my truck on the freeway...
It's kind of ridiculous for someone who's truck runs fine on 87 to say that it's a waste of money to run premium in a truck that doesn't run fine on low octane fuel. Is it that hard to believe that different situations require different solutions?

Well, In our trucks unless there supercharged theres no reason for running a high octane fuell, unless you have a full blown out racer 22re, the compression in the 22re is low enough so we can run the cheap stuff, most cars are like this, you can but high octane but youre just being stupid paying more for gas

On the 1992 4runner manuel it say 91 (premium ). I notice a diffrent from 87 to 91 and the compression on these 3vze are 170 psi each cylinder. Just don't use SHELL gasoline I don't know what they use in there gasoline, it cause a missfire or even hesitating when you press on the gas pedal.
