I finally started paying closer attention to where I buy my gas

[u/grig_orig]

Just to start, I take a pic of the pump display and the odometer at every stop for gas. I only buy full tanks with an exception here and there if I have to, just to keep it simple.

I did this from almost the very beginning of ownership. My record by now is fairly long so I figured I would finally take a closer look at trends and see if any patterns were there that might explain them.

I use an app to track it all. Because I am always taking pictures, it’s easy to fill in the data at my leisure. It’s also easy to go back and see exactly where I got the gas in question.

During the last bad stretch I found that all four times, I was getting gas from the same station. I would’ve stopped going back after the second tank if I would have paid attention. But I was just collecting data.

Earlier in my ownership of the car, the mileage was very poor for some time, despite new plugs, air filter, etc. I found that the gas came from several different stations, so there was no pattern there. At this point I was paying close attention to where I bought the gas, but nowhere gave me a consistently good result.

It wasn’t until I put better tires on the car that I started seeing the sort of mileage I expected when I bought the car. It turns out the new tires the car were sold to me with were sub-par. The new tires have been amazing and really opened my eyes to how important tires really are… not just for things like traction, but mileage and acceleration. Also, fun!

Anyway I just wanted to share and see what tips or stories were out there. Thanks for reading.

TOP TIER is the phrase you are looking for.

Costco is not a discount station in the sense you are referring to. They are a discount club, yes, but their gasoline meets the TOP TIER requirements just like the other stations that do.

Bro calm down.

Yes all Costco gas stations are top tier rated. They have a built in system at their facility to dispense the additives to the fuel when it's delivered. It is all automated so that people can't mess it up.

Buddy, calm down. Not one is yelling or shit. So sit the fuck down. 1, no not all Costco stations are top tier rated the one near me is NOT. 2, yes they can fuck it up the costco near me for sued the shit out of for destroying engines by adding TOO much water to their gas. They got greedy and cost people their cars and engines. I would Never trust Costco gas. Ill use top tier rated gas along with gas I test myself at the station. To know it's good. My car is worth to much to put shitty gas in. So now that we know you are wrong about literally everything you just said, have a great day.
