It's because they don't make a Mobil1 that meets both Chrysler's specification requirement and viscosity recommendation. Between the choice of two "wrong" oils, they're recommending the one that won't void your warranty.

I just bought 7 quarts of Pennzoil Platinum Full Synthetic and a Mobil1 Extended Performance Oil Filter from Walmart. I'm either taking her in this week or next for her 5K oil change. I changed her at 1K...will now do a 5K and then every 5K from there like clockwork. Been using PP for years and really like their products. IMPO, and based on many on-line reviews over any years, Mobil makes one of the best filters and it is only $10 at Walmart.

It’s simple. Follow the mfg requirements to maintain warranty. Deviate at your own peril if you have a claim down the road and can’t prove you followed their requirements. Extended warranty will not protect you if you didn’t follow the original requirement.

It has to do with the mds solenoids

Just a quick comment, if the manual says 5W20, why do folks always want to use something different and question the engineers who designed the engine??? It's not like 5W20 is any more expensive than 0W20 or 5W30 so why not just make life easy and use what they tell you to and call it a day.
My guess would be....distrust or skepticism towards engineering standards and/or vehicle owner maintenance protocols

Well I ordered the 0w-20 which was listed for the 2019 ram hemi on Mobil website but the dealer did say it would void the warranty, and wouldnt put it in.
I didnt look at the Ram manual, I knew I wanted Mobil 1 oil so I just went to the Mobil website, entered the truck info and then ordered the oil. I just cannot believe that Mobil would list oil on their website that would void the warranty and the dealer would refuse to put in the truck, its not like they have thousands of products, they mainly just sell oil and should be able to get it right.

It say in the OWNERS MANUAL 5W20. Many things listed on the Internet are incorrect.
The manual also calls for Chrysler spec...and Mobil 1 (regardless of grade) doesn’t meet that either.

Gotta' love our newer tech engines. (Ol' fogey story coming)
Back in the day, you dumped in straight 30, 10w30, straight 40, 20W-50, about anything you found... I was working at a gas station back in the 70's and I guy came in and asked for some of the waste oil out of the can that we had by the pumps. We drained oil, ATF, whatever was liquid in there... So he dumps it down the crankcase filler and tears off in a cloud of smoke...
Now even my lawnmower engine specifies a viscosity...

I wouldn't change the higher number to anything else besides 20 because this is directly related to the size tolerances between moving and striking parts within the engine. I put 5W 30 in my old Hemi and noticed the MDS didn't come on as much and was rougher so back to 20 it was. I don't see any issue with going to a 0W from the 5W because this actually allows for better viscosity and protection of your engine. At the Synthetic oil particle level this allows oil parts to get into even harder to reach areas and lubricate them. The only reason IMO they don't endorse this is due to them wanting you to spend your money at the dealership on their oil. As has been said Zero Weight, Zero Problem.

I think the last paragraph on the left side of the owners manual
"Lubricants that do not have both the oil certification mark or the correct SAE viscosity grade number should not be used". Says it all. I think they would have the right to deny a claim if they analyized the oil.
My wife had a 2009 Journey, and the engine let go, but could not say anything because I kept the oil changed, and used the proper oil viscosity called for my the owners manual. I used Mobil One and they said the engine was very clean except it let go. Got a new engine, no money. So, I will keep up with what Ram says. I do my own oil changes, but put in full synth oil that Ram states.

Not sure what this means as the cost of 0W20 and 5W20 is the same and most dealers have both in stock

Correct, (Fixed it above) they are both expensive at the dealer not just 5W. I can get my Synthetic for a better price than the Dealers oil and when I switched to Mobil 1 I noticed my MDS on more and a fuel economy increase. I also trust Mobil 1 more than their bulk oil. As pointed out above the Mobil 1 0W-20 meets the MS-6395 Chrysler Spec.

I just supply my own oil and filter and they charge me $17 for the labor.

That is a great deal. If they only charged me $17 I would gladly let them do it.

If you supply the oil and the filter and all they do is the labor...what did they say they'd charge you? I do this with all of my cars and every dealer (Subaru, Infiniti, RAM, Honda) has been between $17-$20 for labor only on an oil change.

I haven't asked them on that one, I guess it could be almost as cheap. The biggest headache for me would be the scheduling and time out of my work schedule to drive it over there and drop it off and pick it up. For your service record this is a great way to do it.
