I'm really weird about my gas, some may even call it OCD. But I ONLY get my gas from a local gas station (called Heffron's, its a sunoco station). It's the only place I go for my 93 Octane, because I KNOW the owner of the company, and he has his own fuel tankers. The gas pipeline is like 4 miles from his station, he goes directly to the pipeline to get his gas so I know where the gas has been.
Alot of stations with multiple stores move their gas around, an example. Station X is out of 87 octane gas, well Station Y has 1000 gallons more than they normally sell in a week. So they take 1000 gallons from Station Y and deliver it to Station X.. Which sucks all the sediment and stuff off the bottom of the tank, and puts it into Station X's tank.
Also, I don't fill up my car within 4 hours of the fuel tanks at my gas station being filled from the tanker. As when the tanker is pumping fuel into the underground tanks, it kicks and stirs up all the sediment and crud at the bottom the tank, and where does that go? Into your gas tank! I ask the owner every time I fill up, when he last put fuel in the tanks. LOL so as you can see I am VERY VERY particular about what fuel goes into my tank.
Just started using Mobil 91, it seems to make my car run and sound meaner with the Diablo tune on. Chevron is good, but Shell makes my Charger ping too much, but I use Shell 91 octane still in my 97 Ram, it seems to like it
I go with whatever is cheapest. As long as it's 93 Octane. (91 Octane out here since people do not believe in 93 Octane. But IMO, I think it's cause only MOPARs can handle 93 Octane. But what do I know? I still do not understand why people would drive something other than a MOPAR).
