Gumout 510021W-6PK Fuel System Cleaner, 6 Pack

This item is good for gasoline automobiles. I use it in my personal. I sent this to my daughter so she could use in her car every other fill up.

Arrived on time but note that several bottles leaked through the box. I ordered these at least a dozen times and this is the first time one arrived leaking. One of the 6 oz bottles leaked out to the bottom of the small diameter neck. All bottles are usable. I use these in my S10 every fill up!

This is a great Product and helps the running of your cars and trucks!

I put in a bottle once a month, it certainly couldn't hurt, and with the prices they charge now , it just might help in the long run.

Trusted company that’s been around for years. Smooth idle & acceleration after just one bottle. Most manufacturers recommend fuel injection cleaner about every 3 to 5 thousand miles. Buying in bulk just makes it cheaper.

Great stuff

I am a big believer and using a product like this once a month! If you’re in California using a discounted gasoline supplier like Costco or Sam’s Club you really don’t know the quality of the gas! Keep your feeling injectors, gum, free, and the combustion chamber and valves clean, you need to run an additional detergent product with your gas! Sometimes I use a product like this with seafoam, which is even better at more expensive!

Have bought this pack a few times now and it seems to work like it should
