 Wawa vs Shell gas
I've been always using Shell premium gas and my car's gas mpg has been in the average 26mpg, according to the LCD odometer. I do a lot of city driving every day, and also do a fair amount of highway driving on occasion. For the first time, I had to use Wawa (premium) gas because I was out of town and driving home at midnight and all of the local gas stations were closed, except Wawa. So the next day (today) I went back out and ran some errands and checked it again, and it was in the near 32-33, according to the LCD. I thought this was weird because I've heard a lot that Wawa gas is pretty crappy, and Shell has good gas and all of the delicious additives to it. This ins't exactly conclusive yet, and I'll keep checking it throughout the week. Anyone have any thoughts? |
