Why pinch pennies on a $70k+ vehicle like that?

To save money for mods.
I would fill it with Ethyl when needed, but for my short commute, why waste money?

he’s in EU so it’s 100 RON which is about 95 for us (R+M)/2.

The EU rates octane with a RON number - the US rates it as (RON+MON)/2 or AKI (Anti Knock Index). Wikipedia actually does a decent job explaining the different ratings. In the US we use the AKI which is a more meaningful number (IMO) - EU simply uses RON which is far less meaningful on it's own.

In the South West finding 93 is a chore, or it's very expensive. If you add a can of Octanium Unleaded to a full tank of 91 octane it'll bump you up real close to 93 octane for about .50¢ gallon.

I told the dealership not to fill my truck up with gas when I bought it on 3/31 as I wanted to fill her up myself with 93 octane from Costco (Top Tier gasoline). So I told them make sure I have enough to get me up to the Costco down the road. Sure enough, I filled her up, and was getting 18 mpg on the way home (that’s well over 600 miles on a tank)—I had to drive about 250 miles across Florida to get home. I have been running Costco premium gas for years and all my vehicles have performed great.

You can’t beat Costco’s pricing for premium gas as their pricing is normally close to what regular gas costs at non-wholesale top tier gas stores. Plus if you have the Costco Visa, you get 4% back on Costco gas.

Disclaimer: I really could care less about MPG and the cost of gas. I bought my first Raptor (Gen 1) when gas was nearly $5 a gallon. All I care about is the smiles per gallon and there have been many of those throughout the years. And yes, I may be biased a little bit

We have a small locally owned chain of 5 or 6 Phillips 66 stations around here that have 91 octane with no corn juice in it. I was running Chevron 91 with corn squeezins' all the time. Switched to the no corn juice 91 about 2 months ago. Now when I fill up weekly, my miles remaining went from 535-45 to 585-95 every tank. And I do not drive gently. Always over the speed limit and romping on it whenever I feel like it. Engine runs noticeably smoother and quieter also. I am a big fan of the Techron additive in Chevron and Texaco gas, but I am now a bigger fan of no corn juice. Costs a lot more, but I don't care. Worth it. If you can find it, try it. You will like it.

91 is the highest that Costco sells in the Phoenix area, that I've found.

Costs a lot more...

I'm curious, how much more?
