[This review was collected as part of a promotion.] I received this product for free in exchange for my honest opinion. STP ULTRA 5 in 1 Fuel System Cleaner works well to make my gas last longer. I used this in my 2010 Subaru Impreza and the only noticeable difference I have seen so far is my gas lasts longer. It was also well packaged since it was delivered to me. I do recommend this product if you have a used car and are looking to get more miles to the gallon.

[This review was collected as part of a promotion.] I don't have any issues with my car but I put this in proactively. It couldn't be easier to use. Just make sure your gas tank is at least half filled, Open up the bottle and just pour it into the gas tank. Haven't noticed any changes but that's a good thing since I had no issues prior. It gives peace of mind that you are helping extend the life of the engine.
