A good cleaning additive for cars with 75,000 miles and more
Robert K.✓ Verified Purchase•October 5, 2023
Simple and effective gas additive. Noticeable smoother running engine after I added at 75,000 mile service on my '11 Civic.
Before Oil Change, Or Anytime Fuel Tank
Joseph Martin✓ Verified Purchase•September 17, 2023
Something not explicitly stated in the description is that this fuel/oil additive, can only be used in oil prior to an upcoming oil change. It is not for putting in the oil way before a scheduled oil change, so if you use full synthetic and don't generally get oil changes on the regular like some drivers, this is not something to buy for that purpose.
So I instead emptied the whole can into my gas tank, because it's getting cold here in NYS and with studded tires going on I needed to try anything to keep my fuel efficiency in the green. I might drive a Chevy Volt, which gets 70 MPG in the summer, but winter kills the charge on the battery and even on a 4 cylinder engine I'm working through close to $20 a week on gas. Goodness. (I know, I'm being sarcastic, that's pretty much nothing compared to 80% of the other drivers out there who drop $70+ a week on gas, but for me that's a lot when I normally spend less than $7 on gas a week.)

I love the product
General299✓ Verified Purchase•September 9, 2023
I love the product, it keeps the car running smooth. I follow the directions and add one once per quart of oil about 200 miles before an oil change and it seems to make a difference there. I also add it to the fuel tank every other fill up. I've noticed better gas mileage and a quieter motor since using this. I got the information from a you tuber called Project Farm who shows how this really works.
My only complaint is that when Amazon packages it, they lay the cans down in the box. The containers often leak when shipped that way. I have one of three now, that is about 1/4 empty when delivered. The box is a mess. Hey AMAZON, These need to be shipped up right with a THIS END UP label on them.

Great fuel additive
L. Capobianco✓ Verified Purchase•August 13, 2023
I use this to add to my tanks of non top-tier fuel to help clean the motor and injectors. Top Tier fuels normally have proprietary additives that help clean you engine and fuel injectors. This additive helps to fill this need when I use the non Top Tier fuel via company card so my engine won't suffer. Do your research, you will find Seafoam is one of the better choices
