Yea I was on a road trip and had to stop there so figure I would give it a shot since I figured it should be similar to other brand gas but maybe not....
Here's a shocker. All gas is the same. Regardless of where it comes form, it all gets mixed in the big holding tanks at the terminal. If a Conoco and Shell tanker pull up at the same time, they get filled with the exact same gas. However the Conoco truck will get the Conoco additives, and the Shell truck will get the Shell additives. The additives are what makes gas brands different. The name brands have high dollar chemists and testing facilities to develop their additives. The guys that sell what I call grocery store gas don't. Makes a huge difference, especially in preventing knock. With cheap gas, you get what you pay for...
Also some states have what they call winter and summer formulations. The winter stuff up here usually sucks vs what they provide in the summer.
Just wanted to get that out there...
A couple of things I watch for when I get gas. Is the station really busy? They're the ones I fill up at. Slow stations with stale gas are more likely to accumulate water in the gas. A bad thing. Also I never fill up if the tanker is there filling the station's tanks. It stirs up any sediment in the tanks. I don't want that crap in my fuel system.
I always use name brand gas from busy stations. Been running Conoco for years in my Jeep. But Shell is good too. That's all we have up here. Exxon and the other big names pulled out long ago.
