Default Sinclair Gas?

Recently, my usual Shell station that I stop at to fill up the car to get to work turned into a Sinclair station. According to Google they're on the top tier list, but I've never heard of them. Does anyone have any experience using their gas? I'll find another place to fill up if I have to worry about their detergents not being good enough.

Damn I remember the dinosaur now. Getting old here. I remember when I was a kid, they used to have guys in white outfits and hats that would fill you up, check oil and wash your windshield. Times have changed. Miss those days.

Not as catchy as "you can trust you car to the man who wears the star".

I don't know where the koolaid of Shell is the best gas started.....any top tier gas will work fine

I personally use Sunoco 94....forced induction and all.

Back in the day, who knows what happened with gas. Today from what I'm told, the basic gas comes from the same pipeline and goes out in the same truck regardless of the brand. It's what's added when it's delivered based on the gas station brand that makes the difference. If you run 91 Octane Non-alcohol fuel, I've used Shell, Quick Trip and Holiday and not had a problem with any of them.

"Sinclair nickel gas" refers to a historical gasoline additive from the 1960s used by Sinclair Oil that contained nickel to improve engine performance and reduce wear. This additive was called nickel isodecylorthophosphate and helped prevent engine knocking, reduced octane requirements, and prolonged valve life. While the historical nickel additive is no longer used, modern Sinclair gasoline now uses a different additive called DINOCARE® as part of its Top Tier™ certified fuel, which cleans the engine and improves performance

There are 1,715 Sinclair stations in the US. Never had a problem with their fuel, use 91 Octane on a boosted LS7.

This I understand, but having never even hearing of the company before, I didn't know how valid their claims were. As long as they're top tier I don't care what the logo looks like, although I do have a preference for Chevron, primarily because they use Techron, which I am very familiar with.

Last time I saw Sinclair gas was years ago on a vacation in Nevada, we were on our way to the Extraterrestrial Highway and Rachel Nevada. I stopped there to fill up cause I didn't know when I'd see another gas station. Great memories...

What's funny is that you think that your assumption is right. I'm far from young.

I believe that gasoline is a commodity like home heating oil, #2 yellow corn, and USDA cheese.
From what I understand, gasoline is initially loaded into a tanker-truck as a base generic fuel, and before the truck leaves the fuel depot, the necessary additives are added to the fuel in the tanker to determine the brand and grade.
