Top Tier Fuel...I was 100% wrong
Your car uses Piezo injectors. They don't like low quality additives. Those are not cheap to replace.
Call me superstitious, but once on a long trip in my old ML430, I could not find TopTier gas. So I loaded with the off brand (mom & pop) premium. Now I always like to see my mileage. I swear, I got a lot less per mile on that cheap gas.

I know many extremely wealthy people that are also pretty frugal.
Go troll somewhere else.

A better equation is not about getting Top Tier or not, it's about how. You can buy top tier gas and get the PEA already in the gas, or you can buy fuel additives that contain PEA. A bottle of Red-Line Fuel treatment, which has the highest concentration of PEA, cost around $12, or $6 for the basic Techron fuel system cleaner, which has around half the PEA. When looking at those options it's cheaper to buy Top Tier gasoline than buy the additive by the bottle, and you have the additional benefit of a constant stream through your fuel system.
We don't have a local Costco that has a gas station. The one in Wheaton has one but its too far to drive for gas. I like to run Shell, and theres a station right down the street from my house. Whats funny is theres another Shell across the intersection that is always 20c cheaper...within eyeshot of each other. That one is on the inconvenient side of the intersection though so I just pay the 20c more lol
