I have a 2020 and the book says it recommends 87. What do you put in your tank?

How about 'Sex Fuel?' Put that in a vehicle with an engine not designed for it and you're screwed!

Question is: Why would you not use what's recommended by the folks who designed and engineered the vehicle? Makes no sense at all from either a performance perspective (HP gain vs fuel $ increase) or economic perspective (MPG gain vs fuel $ increase).

I was always told that higher octane fuel burned cleaner which meant less build up in the motor. Have I been lied to all these years!!;)🤣😂

Yes. Octane rating is nothing more than a fuel's resistance to pre-ignition (knocking).

I assumed that would be the answer. Nothing surprises me anymore. What’s the best way to keep the motor free of sludge and carbon build up? I have used Lucas - Tune Up in a Bottle fuel system cleaner. Is this stuff any good or another hack like the high octane fuel?

The question should be what ethanol content.
I put some E15 in mine and ran very poorly. At least it burned it up fast.
Mine gets 87 octane with 10% ethanol.

Agree with MI-Acadia. Top tier gas only, regular oil changes.
GMC manual states the same. And if no top tier fuel available in your country, to add (Delco) fuel additive every oil change.

It's difficult to get away from E10 gasoline these days. The winter/summer fuel thing is largely a myth. Most suppliers don't make the change from summer fuel (E0) to winter fuel (E10) and back any more. E10 is a supposedly "green energy" thing.

Few hours away, and a different world in some ways.
E0 and E5 are everywhere, just gotta pay the piper. And I've never heard of summer and winter fuels.

We had that in the Denver area years ago when methyl tert-butyl ether (MTBE) was the popular fuel 'oxygenator' added to gasoline. It was added for winter months to 'supposedly' control air pollution, then not added during summer. Denver wasn't the only area to do so. The terminology seems to have stuck with folks country-wide since the switch from MTBE to ethanol. We've also seen an increase in E15 supplies recently. GM doesn't recommend using that in a lot of their vehicles unless the vehicle is set up for flex fuel.

Yeah, the manual states E15 max, but I've never seen E15 here.
Our old mini van was Flex fuel. Not that it ever got anything other than 87

I wish we had E5. If I want that I have to fill part with E10 and then top off with E0 . . . about 50/50.

Haven't seen E15 here. A good number of E85 pumps though. Never had a flex fuel vehicle.
I always use E0 in the tank for the yard care engines, chain saw, trimmer, etc. And the outboard boat motor whenever.

Same here for the lawn tractor. Don't think I've seen E85 here now that I think of it... hm
