6.4 hemi power wagon

[Wbud]

I have a 2022 Dodge power wagon with a 6.4 hemi would it be safe to run 5W 40 oil in it because I haul a heavy camper and 0 to 40 seems to Brake down they all I have been using is the ultra platinum 0 -40 I would like to change it to the altar platinum 5w-40
Thank you

You can run a 5w/40 and be ok but the 0w/40 oils will be more robust and RAM calls for Pennzoil Ultimate 0w/40 which is a top performing oil:

Since it getting to be summer and hauling a camper I thought a little heavier oil would work better and not thin out as much

What do you mean by break down? Did you get an analysis of the used oil? Don't be worried about the 0W part.

The 40wt is the number that matters and a 0w and 5w both will be the same thickness/viscosity at temperature so going to a 5w does nothing to make the oil thicker at operating temps.

Have you had an oil analysis done that shows it breaking down? While my personal opinion of the SRT oil is that it's overpriced for what it is, there are several excellent 0W-40 offerings on the market that meet some of the most demanding performance certifications and approvals on the planet.

Yes, you can use a 5w-40 or 0w-40. I'd get the SRT stuff from Pennzoil or similar. You could just pick up some 5w-30 Mobil ESP as well or other similar 30 grade European oils.

I am also very curious how the OP thinks his oil is breaking down.

The Mobil 1 Euro formula is a great option but I would stick to the factory recommendation of 0w/40 for the 6.4L

Good idea.

Pennzoil Platinum Euro 5W-40
Mobil 1 Euro FS 0W-40
Mobil 1 ESP x4 0W-40
Castrol Euro 0W-40

As am I.

The safest answer on earth for most of these questions is : Run M1 Euro FS in 0w-40 and grab a sample at 5k if you need that to feel peace.

What's frustrating and a bit ironic to me is that the two grades of M1 Euro FS are polar opposites in availability. YOu want the 0w-40? You'll trip over it at every auto parts store and wal-mart.

But, you want the 5w-50 version of Euro FS? Good luck proving it even exists anywhere beside the M1 website. Online listings generally show packages that are 5 years old or older based on graphics.
