Premium Fuel or not?

I used to work in fuel retaining. I dont believe midgrade has been tanked as a seperate product for many years.

Almost all modern pumps are "mixer" pumps. The blend between premium and regular, to make midgrade, is done by the pump itself.

Of course with all the additive talk, etc. It's also true that most of our gasoline is delivered at regional pipeline terminals and almost all brands use these same terminals.

Additives are added at the time trucks are filled. But most "Top Tier" labeled gas shares exactly the same additive package across brands.

Octane is one thing for discussion, but additive packages, which are certainly important, are almost all marketing BS. Look for "Top Tier" as it is a specific additive requirement, that most every name brand station meets, but within these brands, they are all virtually the same. Costco is Top Tier, Shell, ExxonMobil, Sinclair, and most all other main brands.
Don't really care what you believe, I asked the guy and that's what he said.

Cool. It's rare for a station to mix midgrade in the ground these day. Usually an older station with older tanks. Newer stations don't put separate mid grade tanks in the ground, they blend at the pump. Believe whatever you want.

The Motor Oil Geek did a YouTube video on Shell premium gasoline and showed how the specific additive package that shell uses for it’s premium fuel, benefits the motor oil, and therefore the engine, based on his oil analysis.
