Octane??

Finally got through the 87 tank the dealer put in, you do notice a difference from 87 to 93. Or maybe it’s just broken in now

forgive my ignorance but what’s better for your engine, 93 octane w/ 10% ethanol or 91 octane with no ethanol?

With no Ethanol. Gas stations that sell Ethanol laced premium are evil. Ethanol free will give you far better milage, better performance and less gunking up of your engine.

no if only it wasn't your first and second born to buy the ethanol free...and essentially all gas stations have to sell to 10% ethanol gas thanks to the feds.... the great stations are the ones offering the ethanol free, if you can afford it

I ran the dealership’s free tank out and have run 93 octane in my 18 since new.

I got lucky, my dealer put 93 in the tank

Why is this still a conversation in 2021?

If its a high performance vehicle, probably smart to put the correct high octane in.

There is one gas station northern Wisconsin, near my parents house, where they sell 91 octane 0%eth for the same price as 93 octane 10%eth. I try to fill up there as often as possible.

God I wish. After doing a quick check around on gas buddy regular is same price around town as the non-ethanol though it’s listed as 88octane... so still not as nice as 93 that’s around here. But might be a better option honestly than ethanol laced 93...
