STP Gas Treatment For Any Gasoline Engine - 12 FL OZ

[This review was collected as part of a promotion.] This stuff is very easy to use just put it in with almost a full tank of gas and your good to go!! I've always used this in my jeep and I can say that it's a great product!!

[This review was collected as part of a promotion.] I didn't expect to notice much — but I did. The car feels smoother and fuel efficiency slightly improves. It's not magic, but as occasional maintenance, it's worth using.

[This review was collected as part of a promotion.] This was my first time trying a fuel additive, in my 65 Mercury Comet. The results really surprised me in how much better it made the car run. It took away all the sputters, and she ran better than she has in some time. This will definitely be going in every other tank to keep my engine running as smooth as it is now. The price point is right when you see the value it adds to the engine. Its a little thing that will go a long way for your vehicle. The engine in my car is Ford 289, and a 3 speed manual transmission

[This review was collected as part of a promotion.] As a mechanic I recommend this be used every 5000 miles or so to keep your fuel system running clean and clear. I use it regularly on my personal truck and have put on 225,000 miles with no problems at all. STP makes great products

[This review was collected as part of a promotion.] I added this when I filled my tank up I added it to 15 gallons of gas. I noticed my car was running smoother I was afraid it would have a strong chemical/gas smell there wasn't any smell that I noticed. It was easy to pour in without spilling everywhere. I also noticed I didn't have to fill up till a couple days later. It's something I will definitely be adding to my monthly routine with my vehicles.

[This review was collected as part of a promotion.] Unfortunately my product leaked during shipping- however what was left I added into my tank! I have used this product for years after recommendation from my dad- makes your tank cleaner and car run smoother. A must have if you live in cold weather!

[This review was collected as part of a promotion.] Disclaimer: this is my first time using a product like this. I also used it during the time I needed an oil change. What I can say is, this product gave me the stretch that I needed to make it to my maintenance day. My car didn't feel sluggish and I was able to travel my daily commute sometimes between 25-30 miles a day without needing to constantly top off my gas. I didn't too much smell anything and the packaging is very functional for pouring the product inside. All in all, I would purchase this with my own money.

[This review was collected as part of a promotion.] Small sleek bottle easy to store. The directions made it easy to follow even for a woman! It was great to add i to my fuel tank as extreme measure. My car ran more smoothly
