    • Better than expected
Size: 16.9 Fl Oz (Pack of 1)
I purchased this product a couple of times now and I'm really pleased with its quality that it brings to my gas mileage and the smoother my engine sounds. I've used other treatments that were lower in cost which are considered good however this product is a bit pricey to be purchasing too often regardless of its performance which is great. I would prefer this product overall when it comes to performance, functionality, as well as speed just can't really see purchasing too much. I do still have leaks but products can only do so much depending the problem ... show more

    • My favorite fuel/injection cleaner by far

I can tell a difference every time I use. Great results while using on four different car brands.

    • Small mileage improvement
Size: 16.9 Fl Oz (Pack of 1)
I used two tanks with this product. I noticed a small performance gain and mileage improvement. I'm sure it's hard to get big gaines with older engines in SUV type cars. So, not complaining. It did improve.

    • HELPS CLEAN CARBON FROM PISTONS
Size: 16.9 Fl Oz (Pack of 1)
The product is economical and I cannot see inside my engine, BUT it helps clean the engine from the inside and doesn't interfere with performance, too. This is a stabilizer similar to what all the gasoline companies add to their product, but more concentrated, too, so it does help. I'd recommend you use it once every month or two - I have added it more than once to assure the carbon is cleaned. Moreover, there are leak stopping products for transmissions, engines and coolant - these are economical and the products work most of the time eliminating leaks and swelling the seals, etc. GO FOR IT!!!! ... show more

    • My car has been rejuvinated.
Size: 16.9 Fl Oz (Pack of 1)
My 4 cylinder car has 117,000 miles. It was running okay, but it had a lost little bit of zip. I added this product into my "almost empty" gas tank. After driving for maybe 10 miles, I then filled the tank. I didn't notice an immediate improvement. But after driving for maybe 100 miles, I can honestly say that my car seems to have more power now. When I need to accelerate quickly, it takes off like it did when it was newer. This stuff seems to work. ... show more
