About Us
In October 1954, three businessmen with a mere 3,000 dollars in start-up capital introduced the first STP product in St. Joseph, MO. STP, began with one product — STP Oil Treatment. It helped automobile motor oil resist thinning at high temperatures and pressures.
Product Description
This two-in-one formula boosts octane and cleans the fuel intake system to restore lost performance.

Octane boosters raise the octane level of your fuel, making it MORE difficult for gasoline to combust under pressure. They get a bad rap as they're sold as performance enhancers, or speed boosters. High-revving, high psi turbo/supercharged engines can benefit from this as it leads to increased efficiency of combustion. High-octane fuel requiring performance cars that only have access to 87 octane gas stations, or fuel that's been sitting around a few months or more can benefit from this too. You can do some research yourself, but if your vehicle does not specifically recommend using an octane booster or a fuel with octane higher than 91 or 93, then it's likely not for you. Maybe if you only have access to low octane gas, but this is an expensive way to boost it by only a little. You're way better off using 93, or 91 octane as your car will take. Using with regular gas if your car takes regular 87 octane gas will do nothing.
I use it in a naturally aspirated 3.8L V6 with 104k miles and it was what was causing me knocks around 3rd gear.
Typically a fuel system cleaner (and this part is important!) which SPECIFICALLY lists the detergent levels, not just the name of the chemical the detergent used, is a better bet for increasing performance, but still only by a few hp in the best of scenarios on the oldest of cars in the worst of shape over a long time after a lot of uses, and typically is only around up to 0.5hp. This one doesn't even list the detergent I don't think, just that it has 'jet fuel' whatever tf that actually is. It's not fuel for a jet, that's for sure (kerosine is what jet fuel actually is).
There are way way better options for boosting performance, and I'm not sure how this would handle in a system that can't take varying levels of octane. Snake oil for many, but it does have it's uses and works for some very specific cases and again, it does not make sense to me yet why. I have some unknown issue, in a 3-year-old car with a ton of miles for the years, which can take variable octane fuels. I likely have some hairline crack in my fuel system somewhere leaking vapor or letting moisture in. **edit*- it was this octane booster which was contributing to my tranmission knocking issue. After stopping use and going down in fuel grade for a month, it's running like new again.*
Not sure if I noticed much of a difference at first but after my 6th or so application I certainly did. So I bought a case and now I do the monthly subscription. I definitely notice better throttle response in 4th and 5th gears. It's like she's ready to roar and what a great feeling it is when the gas peddle is that touchy in a muscle car.
I think the cleaning properties took a little time to do their thing and is why I'm feeling the pep. I am a big believer in adding gas treatments every oil change to counter the crap that goes through your injectors. I don't trust gas with ethanol which attracts moisture and causes corrosion.
With this product I'm getting true 2-for-1 benefits with the boost of octane and keeping my fuel system clean. Plus it's way less expensive than buying premium fuel which may or may not help with cleaning. This is a no-brainer-must-have product for anyone who needs or is able to take advantage the added octane.
Only drawback is it is unknown how many points of octane is adds. It should advertise that is adds X per 10 gallons, etc.
I added it to a tank of 91 octane gas, and my engine immediately responded with more torque. It was noticable. Not like adding a supercharger, but you can tell it's pushing a few more pound-feet of torque.
I suppose this could boost mileage, but it just makes it so much fun to floor the accelerator...
I will say that if I go on the freeway and reset the counter, and there's not much traffic, it'll read 35MPG with the air conditioning on all the way until I exit, even if that's 50 miles later. This is in a heavy Acura TL-S with a 3.5L V6. That might be two or three higher than usual. As for city driving, it's worse because, again, it just invites me to accelerate more quickly. Someone with a gentler touch might get better city mileage than me. Hard to say. I make mostly short trips on surface streets, so my mileage is going to be awful most of the time.
