With debates on oil change intervals elsewhere, here is another pointless one, who has ventured into using regular 87 octane gasoline on their GX550? Keep it friendly please
Zero chance of that for me. One of those pennywise pound foolish things in my opinion. Sure if you just drive around without using the turbo. But once you hammer on it, pre-detonation could be real and mess up the engine.
That's all I use. I had a Landcruiser 100 that called for high octane, and I only used regular. At 250,000 miles rust did in the body, and a sold/gave it to someone in TX who used the engine and drivetrain for a rebuild.
