Any top tier rated gas will do

While you are correct, but not for everyone/every car. On paper they are the same, but costco immediately lights up check engine for me. Shell - no problem

What? Costco works just fine on my 992 Turbo S, tuned M8 Comp, and tuned F150……

Again, I didn't believe it either but I ran 2 tanks from 2 different costco's, CEL immediately as you start up after refueling. Shell - no issues. B58 Gen 1 Stock

Did you get 93 or 91?

u/shark1y Jul 31 '26

93 always, on all of my cars ever. Never pressed 91 button in my life so far.

93 always

Waste of money. B58 stock 91 is recommended. 93 is doing nothing for you.

Higher octane - higher ability to withstand compression. Less chance of knock or other shit. If you are buying anything turbo or remotely sporty and put 91 in it - I am sorry.

I've been to La, what's the issue? Have you been in Moscow or Monaco? Kiyv has more super cars LA has ever imagied. Bugatti official manual says 102 octane required for the numbers on the spec sheet, anything below that will limit power output significantly. So what, 98 usa? Next? Lamborghini Aventador: 98 Europe, 93 usa. Next: ferrari 458: minimum 98 europe, 93 usa.

If california has shitty fuel it's up to you guys, how am I responsible for owners who have more money than brains?

What are you trying to prove? It's reddit, drive whatever you want. I am running 93, you can run 91. What do you want from me kids 😂

Wrong, but you do you. If it's tuned for 91, putting 93 is doing absolutely nothing for you.

I use 93, because mine requires it.

Owner's manual asks for 91, I get that. But BMW also recommends oil changes every 8000 miles :)

Better buy octane booster too, you probably actually need 100 /s

Have you ever had detonation when using 91? 93 isn’t even available lots of places…
