Unique to Chevron formulation that has proven — in my vintage (25 years) fuel injected German cars) — to deliver clean engines upon inspection when heads removed for valve stem seal maintenance.

The Very Best Fuel Injection Cleaner.

Great price and product is highly recommended by automotive experts.

Been using this for a very long time. All my vehicles love it. Cleans and restores lost power as well as better gas mileage.

If you use Techron.. this is the only way to go.

Exactly what I expected

I use this in all my vehicles. I like that it can be purchased in larger quantities. Packed well but 3 lids were off the bottles. None leaked because of the foil sealer under the cap. Will buy again.

Bottles came with Only Spanish instructions. The only English written on the bottle was the words "Fuel Injector Cleaner" how am supposed to know how much to use or how often? Why would you sell something in America without English instructions?
