I think the STP gas treatment works okay, but my package took longer to arrive than expected. The 12 oz bottle is easy to pour, and my car seems to run a bit better, but the wait was frustrating. Would buy it again though!

Not what I expected
I was hoping the STP gas treatment would work wonders, but I didn't see much change after using it. The bottle is nice and the design is cool, but my fuel efficiency didn’t improve as advertised. Might just be me, though!

Great for keeping engines clean!
This STP gas treatment is fantastic! The 12 oz size fits perfectly in my gas tank without any spills. My car runs cleaner, and I've noticed fewer issues at startup. I'll be using this regularly from now on!

A must-have for high mileage vehicles
I bought this STP gas treatment for my high mileage car. It’s 12 oz and easy to use; I just add it to my tank during fill-ups. I've noticed smoother acceleration and less knocking. Definitely worth it if your car is getting up there in miles!
