Synthetic Oil

Another note on the mopar oil certification. The cert doesnt care if your engine last past the warranty.

EDIT:

I know that is a little.... extreme. Joke aside. IMO the cert is not that important. Just do your homework on oil for your hemi

 

No Redline viscosity has the MS 6395 cert. They are "recommend for MS 6395". The only oils I know of that are truly 6395 certified are Shell products which include Pennzoil and QS, and I believe Castrol.

 

I believe royal purple also has the MS6395cert.

 

My truck will never see 5w20 oil again cert or not.

I think somebody made up that shit about the msd not working right with heavier then 20w oil. lol

 

My truck knocked on API / ms6395 cert oil, and purred on no cert oil, you can take that cert and shovel it.

 

^^^yup that's how I feel

 

Which certified oils?

Pennzoil Ultra in 5W-30 is readily available and thats what I was going to try for my first change.

 

Someone on this forum just had an engine failure, and was running Mobil1, which is not ms6395 certified. The way I understood what he wrote was that once an oil sample was verified that it wasn't the oil that caused the failure the dealer agreed to year it down and see what happened. The key is getting an oil sample, oil wasn't the problem.

The Pennzoil Ultra does indicate that it meets that Chrysler spec, however I'm pretty sure the owners manual says something like Chrysler "recommends" the use of a motor oil that meets MS6395, see oil filler cap for appropriate grade.
Recommends is different from required. If the the use of an oil that meets that spec is REQUIRED, per the owners manual, doesn't give you any wiggle room should there be any kind of an oil related issue. If "recommends" is the wording, as long as an API certified motor oil of the appropriate grade is used, I wouldn't worry.

As a side note Mobil 1 did in fact meet all Chrysler specs several years ago, when Mobil products were factory fill on a lot of Chrysler vehicles. Now that Fiat/Chrysler is in bed with Shell Oil rather than XOM, the Mobil 1 products stopped displaying Chrysler certs.

 

List of MS-6395 oils.

IMO the MS-6395 cert isn't what you have to worry about as far as warranty is concerned, its the API licensing. RL and Amsoil SS do not have the API donut although SS could easily pass API SN. I've stated this before, the dealer would have a harder time denying warranty work on a top tier oil than on a non API certified $1.29/qt oil you bought on craigslist.

Quite frankly at 4.5 years of ownership of my truck, I only have 6 months left of powertrain warranty anyway. Hell knowing my luck, my Hemi would grenade 1 day after the warranty expires anyway
