Over the years I have tried many different fuel injector cleaners and I am satisfied that Sea Foam IC5 Concentrated Fuel Injection Cleaner is about the best there is. While some gasoline companies claim to have detergents to keep the fuel system clean, Sea Foam really does and gives positive results.

Used the item on 1.8 chevrolet . Slight improvement in MPG. But definitely noticed a smoother engine tick over. Would recommend and will use again

This product seems to work as advertised, gave me a little bit better gas mileage I think, it gets to work really quickly, fairly good value for money. Although if you go by the recommended amount you're still probably better off filling up with premium fuel. Would highly recommend it though if your car is idling rough or you just like to rejuvenate the life of the car a bit.

I was noticing a tick coming from my injectors and being that I have had a good history with SeaFoam I decided to give this a chance and it worked great. Now all I was able to measure was the sound but it seems to of worked, as for mileage improvement I didn't record my before to compare with after but that wasn't exactly why I bought it.

I bought a new boat in December of 2021, came equipped with an 8.1L Chevy V8 with around 300 hours on it. Being I purchased during the cold season, it sat over winter and upon starting it up on the hose in spring I noticed it was idling rough and hesitating a bit at low RPMs. I've been a Seafoam user for years and swear by it, so I decided to buy these highly concentrated bottles instead as the boat tank is 100 gallons. I put 4 bottles in on my first trip out to the lake and after running it for a while I noticed a drastic improvement in idle and it was significantly smoother throughout the RPMs. I add more at each fill up to keep the fuel system clean and the fuel stabilized. Can't recommend Seafoam products enough!

My 2013 Chevy Silverado was starting very very rough for about 5 seconds and then would run fine until the next cold start. Was getting many error codes, too lean, too rich etc. etc. Took it to the dealer and they suggested intake manifold gaskets and a new MEF sensor. Didn't help at all to the tune of $1,200+ later. Engine light back on after the dealer fix and took it to Autozone to use their code reader. This time it suggested a fuel injector replacement so I thought to myself why not try a bottle of this Seafoam as I have heard about it before but never thought I needed it. After adding the bottle to 15 gallons of gas at the station and driving about 40 miles roundtrip in a day. The very next day it started perfectly and the light is now off. For a $5.00 bottle of Magic stuff!!! I sure wish I would have tried that before the dealer fix.

I had the dreaded check engine light come on. Our trusted mechanic said it could be the catalytic converter, might cost $2000+/-. But could try some engine cleaner. I've heard about Seafoam products and watched some videos on YouTubeube and gave it a try. Filled up the tank with gas. Pored in one bottle of Seafoam and about 3/4 of a tank the light went off. Then filled up with premium gas and half way empty the light came back on. Bought two more bottles of Seafoam and put one bottle in about 8 gallons of gas and light finally went off again and then did the same thing again and light has stayed off. Passed the yearly inspection and all is good. I hope you have the same results.

I'm experimenting with this less expensive product and using it as a fuel additive to try to reduce carbon buildup on the upstream [or back-sides] of gasoline direct injection engine valves. Adding it during my gas station stops hasn't hurt engine performance and the use of the product appears to have improved gasoline mileage by at least1-2 mpg in my 2014 Hyundai Elantra. I have not physically inspected the valves. And the descriptions on this product's label do not address or claim efficacy in removing DFI valve carbon deposits. Other Sea Foam fuel additives do make claims that their use reduces carbon deposits.This Sea Foam product label says to "Use every fill up for best performance". I am aware of some competitive products that are recommended for use every 1000 miles or 5000 miles. I don't know if these recommended limited application rates for the other products are based on improving usage cost effectiveness or on avoiding potential engine damage. But, I suspect the addition frequency directions for these competitive products are intended to provide adequate control the indicated fuel quality and engine problems in a cost effective manner. I would follow label directions and only use what you need to maintain performance -> improved miles per gallon.
