STP High Mileage Fuel Injector & Carburetor Cleaner - 5.25 FL OZ (2 Count)

Always an excellent product, especially now that fuel has become so very expensive that any increase in efficiency is a real plus. I drop it in the Prius about every other month.

My mom used this in her car and got way more miles out of it than I got out of my previous car so I'm using it in my current car. I add it about every other time that I fill up with gas.

love that this product helps to keep my 2006 running smoothly and i even get better mpg than the manufacturer stats. I've got 375,000 miles on my vehicle so far and this product helps to keep me racking up those miles!

I had what I was told was a "fuel injector failure" at 90k miles; then another one at 125k miles. I then started using STP High Mileage Fuel Injector %26 Carburetor Cleaner, at first one bottle at every fill up; then I switched to one bottle every other fill-up. I have now reached 181k miles without any further failures. Also, all of my pollution control valves are original equipment. Lucky? Perhaps, but I don't believe in 'luck' when it comes to engine performance. I highly recommend this product if you want your vehicle to last.

I have always purchased this brand and have always been satisfied with the results.

Works really well in my truck

Not really sure if he noticed any differences, but I always feel better putting some in every once in a while. for good measures.

Snake oil, doesnt actually have any of the good detergents or scrubbing agents for cleaning fuel injectors or removing carbon build up in manifolds

The twin pack a few injection cleaners one of them had a hole in it and leaked all over my product in the box and it's sinking up my entire house.

It now only treats 15 Gallons, not 21 gallons anymore. Will not buy again.
