My son put a performance chip in the car and then put regular gas in instead of the required high octane. How can I remove the gasoline presently in it so I can replace it with high octane? I do not have an owners manual.

Low-octane "regular" gas is usually all that is required. Octane is only a rating of the fuel's resistance to engine-damaging pre-ignition ("knock") in high-performance engines (that few people have). Low octane gas is less expensive and a better value if that's all your engine requires. Best case scenario you're wasting money by filling up with a higher than recommended grade of gas. Worst case scenario that high octane fuel is building up damaging carbon deposits in your engine because it's not being burned as completely as lower octane fuel would be. Check your owner's manual to be sure. Modern high performance cars will sometimes recommend higher octane fuels because they are engineered to use those fuels. The use of lower than recommended octane will not make your car explode, the ECM (Engine Control Module, aka:computer) will adjust the fuel injectors and spark timing to save the engine and compensate for you cheaping out at the pump. Those adjustments will consist of retarding the spark (reducing power and efficiency) as well as dumping lots of extra fuel into the cylinders to cool them, potentially costing you more than getting mid grade or premium IF that's what your car requires.
NOTE: Remember that engines need less octane at higher altitudes. If your engine does not "knock" on regular, paying more for a higher octane rating is a waste since the increased octane makes no significant improvement to gas mileage and it is no better for your engine. All available fuels have detergent and additive packages.
This will help.good luck.
Since this trips to prevent fuel from pumping in a collision, it is made to be manually reset.
The device on a son's Ford used to trip occasionally on our rough easement. On his car it was located behind a panel in the trunk.
i believe that there is a ball inside the inlet of the fuel tank to prevent fuel spill due to roll over and keeps people from stealing your gas, it sounds like it might be stuck i would find something that you could run down the neck and give it a little nudge. a clothes hanger might work
Fuel comes in different grades due to octane levels, the higher grade the higher octane, the higher price. If you have the owners manual or window sticker, you would see that the car was probably made to run on 87 octane (regular unleaded), I have been through the different octane levels for more than 30 years and I have decided that the cheapest runs as well as the most expensive. The higher octane will sometimes cause an engine to ping or rattle under acceleration, if this happens to yours go back to the cheap stuff and everything will be fine. That is my opinion, others may differ, but I run my BMW on the cheapest I can find and I still get 31 MPG hwy.
replace plugs every 24000 miles or so(two years) buying good quality parts is another good idea. shop around, cheap parts are cheap for one reason. regular tune ups will help your car run and perform better. being easy with the gas pedal will help also
