I was told to use these one every oil change on my new Kia 2022 K5 and my engine literally every time I put this bottle in runs like new again and it maintains it throughout the 3,000 miles if not longer knock on wood so far the stuff is really amazing. Huge advantage of the line especially with engines with GDI that have direct injection of fuel. Especially good on turbos and superchargers this stuff really works amazed I've been using it for years I just had time now to do a little small review but it is really good stuff

This stuff actually works, showing an immediate increase in fuel economy in both of the cars we put it in.That said, ALL 6 containers came with loose lids and foil seals that weren't attached. Half the shipping box was thoroughly saturated. I can understand one, but all 6 bottles? I'd give it 3.5 stars purely because of the leakage.

These are recommended for my care at least every 6,000 miles, awesome fuel injector cleaner.

Highly recommended if you are unable to find top tier fuel. If you have a direct injected gas engine this is a fantastic product and I poor a bottle in every 2000 miles.

Restored power on carbureted boat that was not used for years. Pulled the old boat out with an ‘89 4.3 mercruiser engine and changed all fluids, flushed fuel system, and used carb cleaner spray and did the old rev and block the inlet trick to vacuum out the passages. It still idled rough and had hard starting issues after a few hours of running on the lake. I poured in two bottles of this stuff on a 30 gallon tank and after a couple more hours of use it is now starting right up and idling smoothly as aver. Power is up. Definitely worth the few bucks!
