STP 78574 makes a decent choice to remove build-up that might be affecting your car's performance as it also cleans your fuel intake system. It can be used every time you fill up your tank, but it doesn't raise octane levels very high.
  • works with cap-less fuel systems
  • can reduce engine knocking
  • slightly improves horsepower

  • doesn't have an expiration date
  • reduces acceleration hesitation
  • doesn't harm spark plugs
