Based on the manual, seems to me the regular gas is okay with a bit worse performance/efficiency). But with gasohol, you have to use 91 or higher.

Seems to be a lot of people fighting this one out. And the winner is……
My understanding is: the minimum requirement is the gasoline meets ASTM D4814. And 87 octane gasoline meets the standard as far as I know.
What that is saying is that if you accidentally put regular in it for a bit, it might be fine because the engine can sense knocking and adjust timing to compensate.
“I think we should abide by the premium requirement and call it a day“What that is saying is that if you accidentally put regular in it for a bit, it might be fine because the engine can sense knocking and adjust timing to compensate.
But if you do it all the time, one of those knocks could be too big for the timing compensation to handle.
I think we should abide by the premium requirement and call it a day. It is after all a forced induction and high compression engine, whose operating condition typically calls for high octane fuel to prevent pre-ignition.
Some people risk their GX 460 v8 by putting regular in it, but that v8 is naturally aspirated so it's a totally different scenario.
Lots of things don't make senseIt’s 2024 and we can’t figure out which octane of fuel a vehicle uses/needs.
The more things change the more they stay the same.
Truer words I know not.Lots of things don't make sense
WalMart can tell me how many toothpicks they have in Tupelo, Bakersfield, or London...While I'm in Oklahoma at 3AM, and do it in 10 seconds with no fuss.
If you want a $100,000 car though...Ford/GM/Toyota are like "We don't know when it was built (was it built? NO IDEA!), when it'll show up, or where it is. Like we don't even know the continent. Good luck."
I'm not an expert (that's my out) but my interpretation is that ASTM D4814 is a general standard, and that likely all commercially/publicly sold 87, 89, 91 octane gas needs to comply with.My understanding is: the minimum requirement is the gasoline meets ASTM D4814. And 87 octane gasoline meets the standard as far as I know.
So is it required or just recommended… guess we’ll have to wait and seeMore cars are calling for premium gas but do you have to use it?
There's a good chance your new car calls for premium gas but do you have to use it?www.yahoo.com
what trim level and what are your impressions ?I went to the OK auto show last weekend, and there wasn't one there. There was a 550 though, and I climbed all through it.
Not sure what the trim level was, but it had all the goodies. Beautiful brown seats, third row...what trim level and what are your impressions ?
