Each 5.25 fl oz bottle is designed to treat up to 15 gallons of gasoline and is compatible with all gasoline engines, including cap‑less fuel systems. Use one bottle with every fill‑up to help maintain optimal combustion and fuel flow.\u003c\/p\u003e\n\n\u003ch3\u003eHow does STP Octane Booster reduce engine knock and pinging?\u003c\/h3\u003e\n\u003cp\u003eSTP's formula includes MMT, an octane‑raising additive that increases the fuel's resistance to premature combustion. By elevating octane, the additive helps lower the chance of knock and pinging caused by deposits or lower‑grade gasoline. It does not change engine tuning but improves the fuel's ability to burn more smoothly under compression.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eMMT raises octane rating to resist pre‑ignition.\u003c\/li\u003e\n  \u003cli\u003eReduces audible knock and rough combustion events.\u003c\/li\u003e\n  \u003cli\u003eHelps maintain consistent ignition timing across operating conditions.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWhat cleaning effect does this fuel treatment have on the intake system?\u003c\/h3\u003e\n\u003cp\u003eThe synthetic technology in STP Octane Booster targets deposits that build up in the fuel intake and combustion areas, helping to restore fuel flow and combustion efficiency. Regular use helps loosen and remove varnish and carbon residues that can restrict injectors and intake valves. Cleaner fuel pathways support smoother acceleration and can help engines deliver designed horsepower more reliably.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eBreaks down varnish and carbon build‑up in the intake and injectors.\u003c\/li\u003e\n  \u003cli\u003ePromotes steadier fuel flow and more even spray patterns.\u003c\/li\u003e\n  \u003cli\u003eSupports more complete combustion for smoother throttle response.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eHow do I use STP Octane Booster and how much fuel does one bottle treat?\u003c\/h3\u003e\n\u003cp\u003eUsing the product is straightforward: pour the entire 5.25 fl oz bottle into your gas tank before or after filling. One bottle treats up to 15 gallons of gasoline, so match usage to your tank size or use with every fill‑up for ongoing maintenance.
