I am a senior female and I try to keep my year 2000 car in good shape.  I like to use a product to place in my car's gasoline tank to help my car.  The instructions for use of this gasoline additive are easy.  You go to the gasoline station for a fill up, but first empty all of this product into your gasoline tank, then fill it up with gasoline. Very easy to use.

Gasoline additive

walmart.com

I drove less then a 1,000 km since I added it  and I can feel improvement on engine response. I wonder what's after 20k? More review to come.

Easy to use, for decent price

This is the first time I have used this product, and so far a half tank in I have to say its impressing me so far.  For sure I have heard of the product, seen it on shelves, read reviews etc., but have always used others, so this time I decided, heck why not?!  As I stated, only half a tank in but impressed....if things change I will modify my review, but a little voice inside my head says I may not have to!  Fingers crossed that I finally found a product I can trust and believe in!, and ohhh yah, Walmart has the best pricing on this anywhere I found, even compared to Amazon!, keep up the good work!!

Gum/Out - Power IN!!

Good quality and price

I use this in my gas once a month as well as I pour 3 capful's in each tank of gas for my lawnmower and snow-blower to keep the fuel systems clean. I have NEVER had a fuel gunk up problem in any engine that I have treated with this product. I had problems in my lawnmower and snow-blower before I used this with gunked up carburetors so I know this product is working. I have used this stuff for years now. I honestly can't say enough good about this product. Follow the dosing on the bottle for your car (more isn't better and you don't need extra than they call for). You will feel the difference. My lawnmower and snow-blower start with one prime and then one pull... Even after sitting for the whole season, with old gas! (Their other products aren't as strong and effective as this one from my real-world testing.)

Well worth the money

I am skeptical of most automotive additives and don't use them. However, I did read a couple of articles on cnet.com that extolled the benefits of Gumout  High Mileage Fuel System Cleaner and Gumout High Mileage Fuel Injector Cleaner. A month or two later, my high mileage vehicle (175,000) started running so rough that it would stall at a red light. I tried the fuel injection cleaner first because the injectors are usually the most likely suspect. The engine made an obvious improvement before I finished a tankful of gasoline. Then I tried the fuel system cleaner with the next fill-up and got additional improvement. I have turned from skeptic to believer.

Made a difference after one tankful of gasoline.

Seems to work. Hard to tell.  25% too expensive, IMHO.

Increases the power of cars with higher mileage

Improve car power

Love this stuff.  Makes my old Ford wagon  run, if not like new, at least like a young car again.  I add a half bottle to my 12 gallon tank every 6,000 miles or so and my engine runs nice and smooth.

Great product.  Makes rough old engine run smooth

Do not buy this product. It leaves streaks everywhere.

Stay away
