Just curious - I'm about 89 octane
Premium which is 93 octane here. Want as many HP as advertised.
I use the cheap stuff around town and premium when I'm towing. Around here, the increase in mileage while towing means the price difference is a wash. So the increased performance is free...
We get treated to 93 here. I haven’t seen a pump with anything higher in years.
will 93 give me more power and mpg?
Yes. I think 87 pulls timing and a little boost. Even at part throttle it's a noticeable difference. I only use premium while towing because power in regular is usually adequate, if not joy inducing.
Regular when not on a road trip or towing then it’s Premium.
Chevron 93, ya I’m that guy.

In my work yard I fill up with Regular. But when I am travelling, I use 94 octane. Can really tell the difference imo. Oh and I selected 2 options in the poll. 87 and +90 octane.
Yes. Using premium will make all 400hp available. Using regular will "detune" the engine down about 25hp or so.
