I put Bestline in my 2017 Ram 1500 5.7 every oil change, and it idles smooth as silk, and gets better gas mileage and quiets the motor noticeably. This stuff will make your engine last and last and last. Make sure to change your oil every 5000 miles and use a good synthetic and Bestline, and you're engine will never be happier.
