Son swears by it!

[This review was collected as part of a promotion.] The STP Octane Booster has been a solid add-on for keeping my car running smoothly. I use it when I want a little extra performance, especially before long drives, and I've noticed my engine runs smoother and accelerates more easily. It's simple to pour in, works with a full tank, and gives me peace of mind knowing it's helping clean the fuel system while boosting octane. For the price, it's an easy way to keep my car in top shape between maintenance visits.

Get the most MPG out of your trip

[This review was collected as part of a promotion.] I used this before a trip in my truck. I wanted to be sure that this would be a smooth trip and I could take advantage of all the MPG I could get. This is easy to use and just needs a small funnel. I've used this brand many times before and feel like this is a quality brand that I trust for my vehicles. Overall, I feel like this helped boost my MPG for the trip. The bottle is slim and easy to hold and add to any type of vehicle.
