No, you don't have too.....but I do about every time....I use Power Service...the reason being I have an auxiliary tank in the bed so I pour it into my 60 gallon tank....maybe not every tank. If I'm running through it on a long trip...I don't use as much....but I definitely do when I don't run her much and it sits in the tank for a couple of weeks.Do I need to be using power service every time I fill my 2019 ram 6.7? Thanks
Because of lackluster “evidence” from “reputable” diesel shops, I use the best.Per a reputable independent diesel only repair service I have had work done and trust, "because the advent of modern diesel fuel is woefully low in critical chemistry ie. lubricity, cetane etc. and is essentially very dry fuel", they recommend adding a diesel fuel additive, whichever brand you choose with each fill-up and no more than every other fill-up. I have seen no reliable evidence to the contrary and have no reason to question them. Considering the cost of these trucks it seems like false economy to save on either not using or minimally adding a diesel additive. So I add it at every fill-up.
If I recall, Power Service was NOT recommended for the 6.7L Powerstrokes because of alcohol content which was harmful to the CP4. I realize that my 2018 Cummins owner's manual recommended Power Service products, but that was with the old, more tolerant CP3 pump. I'm not sure if they are still recommending them or not for 2019.
You got me at Motocraft. Not particularly convincing; unless, of course, we see a Blue Oval branded CP4.5 at their dealerships soon. Since when did we take the word of the folks who decided that CK-4 didn't meet the specs of their mediocre "value added" oil.
I run Motorcraft anti gel in the extreme cold weather because it was specifically safe for the CP4 pump.
Yes. Demulsifiers are a far safer bet than emulsifiers & additives that "safely pass water through the injectors". Diesel 911 is utter junk. There's far better emergency de-icers available. Amsoil's Diesel Recovery comes to mind; though I get some folks don't like the brand, it just plain works. Without destroying fuel separators/filters.
Be very careful of emulsifiers and water absorbers in many of the popular additives. They cause water to be absorbed into the diesel and can no longer be separated or filtered by the truck, allowing water to get into the CP4 pump and cause damage. Diesel 911 is bad too.
