This is a great product, it was delivered in a timely fashion. Received a nice hat as well. Thanks Archoil !
I don't think it's the archoil I'm pretty sure I have a bad injector but thank you .
First time using this but seems to make cold starting quicker.
I have been using, every other oil change. Truck runs very smooth-2019 Powerstroke. I also try to buy fuel at high usage stations.
Haven’t been able to check mpg yet but truck is running smoother. I use all the arch oil products.
