A+++ Great stuff. It has PEA which is what you need to clean your fuel injectors. It also has stabilizers to allow you to leave your car for months and still have viable gas when you return. A+++

Pues parece que si funcionó bien, hay muchos productos como este sin embargo si noté que la camioneta recobró cierta potencia. Lo recomiendo

I noticed a more smooth engine performance when I applied the Royal Purple Max-Clean into my fuel. I am still watching out for further improvements as it will take some time to fully realise the benefits.

I purchased a 20 oz can of this at AutoZone ($18.99 + tax). I used the can with Sunoco Super Unleaded gas in my 2019 F-150 with the V-8 engine. I then travelled from VA to GA (8 hour drive) and I definitely noticed a difference. Pick up to merge onto the highway and passing other vehicles was a lot better and I logged 20.2 miles per gallon, which is at least an improvement of 2 MPG. My truck also idled so great that you wouldn’t even think it was running. Highly recommend this product!
