2005 Hemi jeep

[Collie]

As a lurker for a number of years on this site (note low member #) I need advice. Subject is a hemi jeep which is driven very low miles, 3.5 miles to wook, usual short local runs on week ends. I pulled my first oil change at 1300 miles, and replaced it with MC 5/20. I am a believer in the recomended oil (5/20) as a neccessity to keep the MDS system working.MDS shuts the Hemi down to 4 cylinder operation, and is barely imperceptable, mostly thru exhaust tone. The truck only will be used for 5000 miles per year, due to my short commute. But driven daily.I do have occational lead foot on week ends, and it hauls A**. Quite the SUV.
Advice needed is.......should I switch to Mobil One 5/20, OR, stick with MC 5/20? OR Mobil One 0/20?
I have used Mobil One for MANY years, but with new SM semi synthetic SM oils, would it be a waste? Perhaps Havoline? I'm open to all sugestions. I hail from Minnesota, so this is a consideration as well, as many times I'm sure the oil temp is low. Too low. I do take it out on the interstate for a hard run about once a month.
Thanks for your guidance my friends.

This sounds similar to my '00 Silverado 5.3. It will be 6 years old in June and now has 25k miles.

It receives 1yr OCI's or when the OLM lights up.

I now use M1 10-30 with Bosch Premium filter.

Before though it was receiving Pennz and Val A/C 5-30 or 10-30 with Fram filter (pre-BITOG).

If you live near a WalMart, you should buy the 5qt M/C jugs for $9.98 and SuperTech filter and do 6mo OCI's for warranty purposes.

Or go M1 5-20 for 1yr OCI.

Either one will be great IMO.

I'd go 6 month intervals with any conventional 5W-20 and a good filter and be done with it. If your averaging 5K per year, that's roughly 2500 miles every 6 months.

I would go 0w-20 in the winter, 5w-20 in the summer, 6 month OCI.... Personally, M1 is my favorite oil, but it's your call. Either one should be good though.

Motorcraft 5w-20, Supertech or Advanced Auto filters are good choices, good value for the money, and will provide good service for you.

I have a 2004 5.7 Hemi, I run 5w30 motorcraft with an Advanced Auto filter. Have done so since new.

Well, while I was a tech at a Jeep dealership, some of went to school for the new Hemis, and they taught us there that ANYTHING but 5w20 will have an adverse affect on the MDS, as it relys solely on oil pressure to disengage the valvetrain for the shutdown cylinders. Im not saying that it wont work with anything but 5w20, but thats what chrysler says.
