So can it really have been that poor quality of gas this time that I lost so much mileage or should I be checking for a leak or something? I did not drive any differently, more aggressive or in more traffic than normal during this. I have gotten Arco occasionally before and never noticed this before. So is Arco really that bad and I never noticed or was this just a really bad batch? Also, there was some water dripping underneath my car,but I think a little water/condensation is normal right? It wasn't gas.

Couldve been a number of things. Sometimes when i fill up my tank I will reset my MPG meter. The meter will give you the AVERAGE of the numbers. So if you drive for 30 minutes at 70 mph and your gauge is saying your getting 24 MPG- if you stop for a 3 minutes to stop at the drive-thru and your car is still running, the car will find the AVERAGE of 70 mph & 0-5 MPH driving. Meaning the gauge will not be accurate.

If you haven't touched the gauge, then this doesnt apply. But I was wondering one day why i was getting 31 MPG on the freeway for 4 hours of driving and then I stopped to eat and was getting 15 MPG by just letting the car sit.

Hope I help.
