3rd & 4th Generation (1992–1996 & 1997–2001)Toyota Camry Discussion for years: 1992-1996 & 1997-2001
Topics of discussion range from fuel economy, safety, modifications, performance all involving America's favorite family car, the Toyota Camry.
I'm sure it does a little, but does it to the point where it can fuck up anything/rob HP?
Reason I'm asking is that the camry I just swapped into had 3/4 tank full....from 3 years ago. And I wanted to know if I should take the trouble to drain it or not. I was going to drain it originally, but then I saw the filler neck doesn't go straight into the tank.
I noticed that the engine and transmission doesn't seem as fast as it was in my old camry. I'm hoping the reason is just crappy gas or something I can at least fix. I'd like to get that engine's pep back!
Yes, gasoline can go bad. It eventually turns into varnish. If sucked up into the engine, it will gum up/clog the fuel pump, fuel filter, fuel injectors, and may lead to costly repairs. I'd never trust 3-year-old fuel for anything other than cleaning off dirty car parts. I'd would rather spend money on a fresh tank of fuel, than the headaches of a gummed up/clogged fuel system. If the fuel has to sit for a long time, add some fuel stabilizer like "STA-BIL". It'll keep the fuel fresh.

Also if the fuel has to sit for a long time, try to keep it in a SEALED container. This will keep any water vapor from getting in, thats why gas tanks are pressureized!
BTW as a point of interest, a rule of thumb is you can keep gas for about a year max in a sealed container. When you use it, just add small amounts to a tank of new gas.
Alright. How should I do that? Just unhook the fuel filter and turn the car on, let the fuel pump pump it all out?
Why no just pop out the fuel pump (under the back seat) and siphon? You're not building a church here...just get most of the old gas out before filling up with fresh.
I'd think the tank would have a drain, too, but never had to drain a Camry tank so I could be mistaken....
The current pump gas is chemically far different than the gasoline of old. It's more likely to gel, cause rubber to deteriorate and cause metal to corrode. It's less likely to turn into varnish.
If your area mandated alcohol in the gas, the corrosion inhibitors have long since been depleted. But there isn't much you can do about that now.
If the gas is still liquid and the car runs, just top off the tank and drive as usual. For the first tank or two you might not let the level get below about half, then you should run the tank nearly empty and get a tank of fresh gas. This will dissolve any gel, and leave a fresh layer of full-strength corrosion inhibitors inside the tank.
Don't change the filter immediately. Fuel filters are large and can handle large quantities of contaminants before clogging. But if you do plan on changing the filter, wait until a tank or two of fresh gas has been used. There isn't much point in changing out a good filter, only to have the new one immediately catch everything in the tank and lines.
The same is true of the oil and filter. Run the car until it's fully warm before changing the oil and filter. You want all of the gunk washed off the engine and suspended in the oil.

Does gas spoil?
