Watch for bad gas.

Impressive
Still waiting to see what a Track shows

Got this with my 6.1 M6
275/40/20 drag slicks

 

There’s 1 track within 125 miles of where I live and they have test and tune days 6 times per year. Between car shows and being out of town, I wasn’t able to make any of the previous dates, and I’ll be getting a dyno in Minneapolis next Saturday and will miss again. That means that the only time I can get my car on the track is September 18 or 19, and if the weather is bad, I may be waiting until next year. Also, the track recently has some issues with their timing system and they were only doing 1/8 mile runs, which I have no interest in. Sometimes it sucks living in the Fargo area, but what can you do.

 

Nice numbers. But you actually believe that Costco gas is the "best in town". What kind of creepy Costconian town do you live in? Live everything else in that horrible chain, they use the cheapest they can find and package it in bulk - gasoline included. If you want the best gas in town, stick with Shell, Mobil or the best Chevron/Texaco. I have been using Valero premium in my Challenger R/T and RAM Sport and love it. Beware, the Costconians will eat your soul, then sell it in bulk for a cheap price!

 

If you don't like them, go somewhere else. Where I live, they're considered to have the best gas in town. If you're all butthurt about me going there, that's your problem. Lol.

 

Costco is a Top Tier gasoline... I'm surprised at some of the ones on the list.
