Modern engines typically employ knock sensors to eliminate pre-detonation. Not the case?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.
I view that as an insurance policy. And I don’t want to be using that unnecessarily all the time.Modern engines typically employ knock sensors to eliminate pre-detonation. Not the case?
Good point. Retired, we only do about 4K miles/year. I suppose it grinds on me that a modern engine allegedly cannot accommodate various octane values, albeit reducing the performance a tad.I view that as an insurance policy. And I don’t want to be using that unnecessarily all the time.
That said I might be an outlier in this group because I use this car only on the weekends and I’ll likely put less than 5000 miles a year on it so my gas costs are negligible versus those using it as a daily driver.
No one said it can’t accommodate. It absolutely can. However every trade off has a price.Good point. Retired, we only do about 4K miles/year. I suppose it grinds on me that a modern engine allegedly cannot accommodate various octane values, albeit reducing the performance a tad.
I have a 2014 GX and have always used regular gas and I’m at 190,000 milesWith 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
