hey i was wondering if any1 else notices this with there car...

i have a 96 ex and it seems that everytime i go to put gas in when i unscreww teh gas cap theres a lot of pressure released from the tank... it's like opening a bottle of soda everytime i open it i get that "pSSsh" sound i know it could happend everyonce in awhile but it seems like it happens all the time... i drive an altima and a truck and they only do this on exreamly hot days... but the accord seems liek it has it all the time. any ideas or is this normal?

 

This is normal

 

the vapors from the gas build up pressure.

 

but should it be so much? its always strong liek opening a bottle of soda ...lol

 

haha yea i know what you mean. it happends too all my cars even my gas can for my lawnmower.

 

pressure equals good... low pressure equal bad

 

i guess then maybe i just dont pay much attention to the altima when im pumping gas....

 

yeah got the 96 EX as well and it does it

on the same note my buddy was in the army as a gas pumper. Like all gov. beaurocracy he had to go through months of training and jump through all the hoops...but due to the vaporization he claims that you get more bang for your buck if you fill your car late at night after things cool off. The gas isn't as vaporized and is denser, ie. higher octane.
