My mother is giving us her car. It's a 93 Camry with only 56K on it. It hasn't been driven or started in about 15 months. It's being stored in a dry climate in her garage. The oil was changed just before she stopped driving it. But no gas stabilizer was ever put in it. We're going to have to drive the car 700 miles across the desert to get home. Is there anything we need to do about the old gas in the tank? Would "Heat" help? Or should we add stabilizer now? Anything else we should look out for? :eek:

Assuming the car has been well maintained up to this point and you plan to keep it in good shape because you want to have it for years and put many more miles on it.
If I was given the car this is what I would do.
Because the oil was changed right before it was parked and it being in a warm climate I think it is safe to drive it without another change.
Ideally gas stabilizer should have been added at the time it was parked so it will not benefit you now. The best thing would be to get as much of the old fuel siphoned out of the gas tank as you can then fill the tank with fresh gas.
Add a bottle of Iso-Heet {at Walmart} {red bottle $2} into the tank this will dry up
Any condensation that might be present in the tank.
Next change the fuel filter.
Also check the battery with a multimeter to see if it is at 12 volts.
Check to see if the water level is up in the battery cells, if you need to add some use only distilled water.
Check to see that all of your fluids are topped up full especially the coolant in the radiator.
Of course check the tires pressures and air up to spec if needed.
These are the most common things to check if a car has been sitting idle for awhile.
If the car has been well maintained to this point then that's all you should need to address to get it up and running good again.
Ensure the air filter is new as this will help you with gas mileage on your trip.
Please rate my answer if it helped you in any way.

You can run the fuel pump on this to drain what's in the tank. Be in a well vent area, be careful, locate the fuel return line coming off the fuel rail. Looking down the drivers side, towards the firewall, look for a 3/8 fuel line. Disconnect and attach a long fuel hose bought at any parts store. Insert into gas can. Now go to the data link connector under the hood, flip open the cover, and get a paper clip to make a jumper. Jump termanals FP and B+. Be ready! Now turn on the key. Fuel will start to flow until dry.
Have a fully charged battery, don't be hooking up no charger after the fact to avoid sparks.

Great idea, kitch428.
