AM is a special car that requires scottish highland cow's gas.

 

No preference on petrol brand here, though I find myself sticking with stations that have good lighting so I can see my car as I fill up 😂 In all seriousness, ethanol content and octane are what I prioritize - though it’s rare to find any ethanol free gas near me (north of manhattan, NY) it’s easier to make sure 91+ octane (93 most of the time).

As far as ethanol - i’m about to add some ethanol fuel treatment to the tank - especially as I’m not using the car while there’s salt and ****e on the roads.

 

Add a bottle of single malt scotch every 1,000 miles... for the Aston, 93 at Costco for me. .I always get into discussions with folks who never seen an Aston Martin... always fun showing off cars

 

its... gas man... just buy premium or whatever and fill er up... not much thought goes into it

 

 

I use a gas station that has the most level entry & egress, and secondly offers a free bottle of water with 8 gallon or more purchase.

 

 

 

There is some variation in gasoline quality, but not much. On my hybrid, I collected enough data to conclude that I did get statistically significantly better fuel mileage with Speedway fuel, compared to Thornton's; and calculated that, even when accounting for the price premium and the slight further distance I'd have to drive to Speedway vs. Thornton's from my house, I'd save money going to Speedway. But I was purely concerned with it from a cost perspective, there. The reality is that, as long as you're getting your gasoline from one of the larger companies, the quality control will be high enough that you won't have anything to worry about.

 

An important point that's being missed so far: The detergency of the gasoline is just as important, if not more so, as the the actual quality of untreated gasoline. In every locale everybody's gasoline gasoline is supplied from the same place. What distinguishes Shell from Chevron from Costco is the additive formulation added before being delivered to the gas station. Otherwise know as top tier gasolines. Top Tier specifies requirements for performance specifications and trademarks designed and is supported by several major automakers.

My wife is Dutch so she makes me use Shell.

 

The only top tier station I have close enough, Sunoco. Everything else is Lukeoil and Wawa, wherever that stuff comes from.

Before they put a new engine in it I wasn't as picky but if you start with clean I'm trying to keep it clean.

 

 

I use ethanol free when I can.
