Is it possible to overfill a gas tank?
So basically I went to get gas this morning before class at a new seven-eleven that had just opened up right across my campus. They were having an opening special where if you bought a car wash you got 10 cents off per gallon of gas. I gladly decided to do this as my car was running on empty and I needed a car wash. It usually cost me $60 to fill up my 17 gallon tank when prices are around $3:50. With the discount it came to about $3:19 a gallon so I put $50 in at my pump and proceeced to fill it up. Around $46-47 my gas tank was full. I had already paid the $50 for gas so I wanted my money's worth and pumped out the last few dollars of gas in so I basically got an extra gallon of gas. Will this cause problems at all or is this nothing to worry about?
As for my car it's a 2002 Toyota 4-Runner with over 150,000 miles on it.
Thanks for any replies :)
