BP vs Texaco

[Ford Man]

I've recently been using either Texaco or BP gasoline and I've noticed I'm getting much higher MPG readings on the Texaco than on the BP. I never thought there was that much difference in gas, but each time I use BP mileage is dropping. Thought I would share this information in case anyone else wanted to see how their results turned out. It's not from just one specific BP station so it's not just that there's a variation in the pump reading, because I've filled at several different BP stations. The MPG differences have been as much as +10-15% using Texaco. I'm going to use Texaco only for a while to see if my MPG results vary as much as in the past using both brands. My driving conditions remain 90%+ the same day in and day out so I don't think that's playing much of a roll and I always top off the tank so I know it's not a variation in fill levels. I'd like for other BP users to try this experiment and post results in this thread so I can see if it's a trend or if it's vehicle specific. If you look at my gas log my last 2 fill up's were at BP and the previous 3 were Texaco and I don't remember about the others.
