Small Bottles. Big Benefits.
Even though STP® Fuel Additives now come in a smaller size, they deliver the same deep-cleaning engine power as our traditional bottles. With ergonomic grips and a tapered neck, the bottles are easier to handle and pour without spills. And thanks to the smaller size, they’re also easier to store.
STP® Super Concentrated Gas Treament
Cleans with twice the cleaning agents of our regular gas treatment.
STP® Octane Booster
Uses maximum street legal level of MMT to boost octane. Also contains a high level of detergents to clean fuel intake system and help restore performance.
Concentrated Bottle Benefits
- 1) Still treats up to 21 gallons (same as 12 oz. bottle)
- 2) Tapered neck and small shoulders enable a snug fit into most gas tank openings
- 3) New 2x concentrated bottles have the same amount of powerful active ingredients as our traditional 12 oz. bottle
- 4) Ergonomic grips make it easier to hold and use with no spills
- 5) Smaller footprint means smarter storage, better portability and less waste
