Gumout Fuel Injector Cleaner/Carb Cleaner Additive 6 oz - 510021W

A fine product indeed, it helped both my 2013 Nissan Altima SV and my 1999 Dodge Ram 1500.. They were both getting low mpg beforehand and now they have came alive and are doing a whole lot better mpg is back and with more pep at the throttle. I highly recommend this fuel injector cleaner to all. It's money well spent.

i have a 93 toyota 22re engine and makes the engine run and idea smoother. I've used it for years and haven't had a reason to try something more expensive.

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!

Well it did stop my fuel pump I was stranded But may be not ,finally got a replacement it rolls out now smoothly my system was contaminated Badly this helped a lot im running a Asian carb. 22r.

This item was a lot cheaper than anywhere else!

The bottle is easy to open. Gumout is a top-notch brand and works well.

This is a recommended product by many mechanics and shops. Plus, it really works.

Does a good job keeping my gas mileage up. It's not the best on the market (those are a little more expensive), but if you use this every tank, it will help. Decent product. My dad used it for years and he worked at General Motors for 30 years, so that's a pretty good endorsement!

Sorry to be contrite — I no longer have faith in gasoline additives because of this product. Find a good gas station you enjoy. Just fill up with 87 gas and the oil companies have plenty of detergents and cleaning soaps in the regular pump gas No more wasting money on false marketing. Additives do not make your engine better.

I bought this to clean the fuel injectors on my car, only needed half of this bottle. But it it ran in to fast almost the whole bottle ran in the tank. That can't be good for anything!
