Default over heard some one at the dealership

a guy at the dealership was talking to this girl, he said, you look like you dont know much about engines, you car had a misfire at a high RPM, we looked over it and everything seems fine, what probly happened is you had bad gas, and hes explained, "gas no a days had all sorts of chemicals in it and if it sits for a long periods of time they evaporate away and that is what cased your misfire


That sounds like complete bull **** to me.

it can take a few weeks, but you also have to think how long was it in the holding tanks at the gas station? It may have sat there for a week before being refreshed, and add that to the time its been sitting in her car.

He isn't necessarily full of ****. Gas can go bad but its rare in a cars gas tank "no a days" because of evaporative emissions stuff. Basically its a sealed unit so nothing gets out.

yeah, but when a moron gets mid grade or regular instead of premium and says "whats the difference?" OR you go to a little gas station that has had their premium tanks at half capacity for a month or THREE because they don't sell much premium. misfires can also be caused by water if you get condensation in your tank, or made someone angry and they urinate in your tank like a honda fanatic I know did to a ford a long time ago... *shrug* anything can happen.

"Bad gas" has become more of a problem since the government decided it would be a good idea to add 10% ethanol to the petroleum fuel supply. Ethanol is an excellent solvent and also absorbs/attracts water, which is why we can't pump E85 through pipelines. The pipelines will corrode.

E10 gas has a very short, 2-3 month shelf life.

Would you say its better to keep your tank half full and not full since you will have newer gas in it it that way?

lol you better hope your gas tank isn't like that or your car could turn into an expensive bomb on wheels

Basically the car salesman has a point, and the OP learned something new today

You're right, she probably already knew what was wrong with her car. She just wanted to see if the dealer tech could figure it out, too

Exactly! It's called a charcoal canister, the canister is just to keep your car from smelling like gasoline due to the venting.

No, you're wrong.

The charcoal canister absorbs the vaporized fuel, then in a purge cycle the vapors are sucked into the engine to be burned off.

PZEV vehicles are allowed almost zero emissions - including evaporative emissions from your fuel tank. It IS a sealed unit on newer vehicles.

Then please explain to me what the charcoal canister is for if the vapors are just recirculated, and please explain to me how the pressure build-up due to the increase in the the partial pressure of the fuel vapor is addressed.

I am by no means an expert in vehicle fuel systems, but I am an "expert" in activated carbon systems among other things.

*edit* looked up a reputable article on the subject myself. Very interesting read. A car's fuel system is by no means a sealed system, but it is certainly more complex than I thought.

Some of my own thoughts: Vapor pressure curves are different for different compounds, so it seems plausible to me that certain vapors are being adsorbed into the charcoal cannister at faster rates than others, leaving you with liquid fuel mixture that could be much different than the original formula if left to sit long enough. Sure, once the car gets running the EVAP system does its job to try and recirculate what it can, but the ratios will still be off. Interesting stuff either way.

It can't be totally sealed or the gas tank would collapse when fuel was used.

Amazing you feel the difference when the fuel came from the same tanker truck, from the same refinery.
