Six Important Things to Know about Gas Caps and Getting Gas

June 5th, 2018 by

Filling your car with gasoline is a routine part of car ownership and these are six important things about gas caps and getting gas that you should know.

  1. Do not overtighten your gas cap. Listen for one click and stop, otherwise you can damage the seal and your check engine light may come on.
  2. Never buy aftermarket or locking gas caps. They do not seal properly most of the time and may cause your check engine light to come on.
  3. Do not turn your vehicle on until the gas cap is replaced properly or your check engine light may come on and you might have to bring it into the Service Department for a reset.
  4. NEVER top off your gas. When the pump clicks off, stop pumping. Topping off can cause fuel to back up into the charcoal canister and cause your engine light to come on. If you routinely top off, you could end up with a costly repair of several hundred dollars.
  5. Never use gas with more than 10% ethanol.
  6. Every 3rd or 4th tank you should use a manufacturer approved fuel treatment or fill your tank with high-test gasoline. When fuel burns it releases fumes, waste byproducts of smoke and carbon. The carbon deposits build up on your car’s fuel injectors, pistons, valves, intake and throttle body. Either the fuel additive or high-test gasoline will help reduce this and help your car breathe better. Carbon build up may negatively impact fuel economy, cold start of your vehicle or the overall wear and tear of your engine. Although it will cost you a few extra dollars per month, it could save you big money in the long run.

Remembering, these six important tips at the gas pump will improve your fuel economy and help to keep your car running optimally.
