So ive done my oil change twice and both times put in 7.6qt with new mobil 1 filter to get to full mark on dipstick, just fyi as manual says 7qt to full... Never had a car need more than spec to get to full before, hope this helps someone...

I have the dealer change my oil and I've gotten used to reading my stick as full at 1/4 to a 1/3 below the full mark. At first I thought I was burning oil, but it consistently stays at the same mark. It did burn a little oil during the break in period, but not now. Just in case, I carry an extra quart.

7 quarts is right at the add line. And then it dipped below the add line. I'm doing my own oil changes from now on. I put almost 7 1/2 quarts of Mobil 1 full synthetic in and it brought the level up to 2/3rds above the add line into the cross hatch area of the dipstick which makes me comfortable with it. I was able to purchase 3 5-quart bottles and 2 Mopar filters from Walmart for a total of $94.43 including tax. That's only $47 per oil change for quality full synthetic and a Mopar filter and gets me an extra quart of oil to put that extra half in and have extra if it gets low before the next change, and have 7 1/2 quarts for the next oil change. Had to get a new engine oil drain plug, the one on there didn't fit any of my sockets and had to use a vice grip to crank it off.

I've never ever heard of a recommendation for a wet sump engine to run it at the low end of oil in the pan (usually just the opposite), but hey, now I have!

I can see how it could possibly effect the MDS if OVER filled.. But would you rather have a higher risk of low oil pressure, less dilution of contamination, less heat dissipation, and need to check the oil more often as it may drop below the low level sooner... Or have the worthless MDS kick in for sure? I'll trust the hashmarks, thank you.

Frankly, I considered going to 5w-30 just to have the MDS not work, but remembered I'm still in warranty ; )

It may be for political reasons but still technically, No.
Copied and pasted from today's Mobil 1 website.

Question: Mobil 1 5W-20 and Chrysler MS-6395 Why is your Mobil 1 5W-20 not Chrysler MS-6395 spec approved? Or if it is, why is the certification not on the bottle or website?-- Josh Eads, Cabot, AR

Answer: Chrysler’s latest revision to the MS-6395 specification calls for a field trial spanning multiple seasons over two years. While we fully expect the exceptional performance of Mobil 1 synthetic motor oil to meet Chrysler’s specification requirements, at this time we are in the process of evaluating our timeline to start this testing.

So this engine is running on conventional oil. My 06' 300C 5.7L had always been synthetic. I've read numerous arguments on varying forums about the syn vs. conv oils. SO if the manufacturer suggests conventional now... Why spend more on synthetic oil? Why is it conventional now?

We also have the Unlimited Mileage/Time Warranty.

I know that a lot has been written about the superiority of synthetic oil. I'm not in a position to dispute it.

But, if the car manufacturers specify dino oil, that's what I use. My MDX said that you may use synthetic, but that using it should not extend the change interval.

I know it is sometimes an emotional subject with most, not all, basing their decision on what they read and sometimes perceived benefits.

Here is my 'guess'. When synthetics first came out they were a good idea, and they have continued to improve. At the same time, oil refining and additives, plus engine manufacturing has improved. At this point in time, conventional oil provides 100% of the protection and lubrication that an engine can benefit from. So while synthetic may look better on paper (and in all the ads) it is over kill.

Remember two things ...

1- I said this was my guess
2- Many people swear their low compression engines run so much better on premium fuel.

Use what makes you feel good. Your car won't care.

Full synthetic is always better than mineral. The molecules in the synthetic oils flow more freely at low temperatures and don't break down at high temperatures as opposed to mineral. That's why their grading is different too, they can be specified one or two grades lighter, which cause less friction inside the engine and therefore save fuel. Because the molecules don't break down like in the mineral oils, that's why they specify longer oil change intervals, but I replace them at every 6K.

My owners manual says "NEVER USE STRAIGHT MINERAL OUL OR NON DETERGENT OIL AS IT CAN DAMAGE THE ENGINE" So, thoughts on the Royal Purple 5w20?? Ive been using it in 5-30 for years in my gm cars, and even in my old 4.slow 2001 jgc "upwards of 22mpg with it"



Oh ya, first post..

2014 Overland 4x4 Hemi w/ORA II and Advanced Tech package.

Ive tried many different oils in my time and honestly cant tell any difference in engine performance in them. I use mobil 1 because the oa holds up (in other engines) and its been around for ever.

On a different note i have noticed my hemi uses very very little oil, and its 5w20 at that... Like 1qt/ 10000 miles of hard driving. And almost no metal on my mag drain plug...


As for dino oil for 8k miles... I just wouldnt do it personally. Oil is better these days but also with less additives like phos. And ca and zinc. The makers ive seen recommending long intervals also recommend syn, like bmw and gm.

Anyone have any opinions on when to change the break in oil from the factory? Should I juse use the oil life monitor ?? I was thinking I may do it at 3500 miles regardless so I could throw some RP in it and a RP filter...... Thoughts??
I always do the first at 1000 and then every 6000 (spring and fall for me) with a premium synthetic will probably stick with Pennzoil Ultra as they consider it fine for the SRT and you can pick it up the 5w20 jugs at walmart for $26.

Did the first oil change at 2874 miles today. Wanted to get it done around 3k miles. Switched to Mobil 1 5w20 and Mobil 1 filter . Was lucky it was on sale at my local Advance Auto store. 5.1qt jug for $32, that included a free Mobil 1 filter! I bought 2 since we need 7qt for the Hemi. The filter was on there pretty tight, lucky I could squeeze both hands in there and finally got it to turn. All pretty easy though, since I have the RRO lift installed. Then finally got the oil life monitor reset, had to look that up.

Looked at a quart bottle of Mobil 1, 5W20, at a Target in Anniston, Alabama yesterday. I was shocked to see on the back of the container that it was in compliance with Chrysler MS-6395. There were quite a few bottles of 5W20 on the shelf, but only 2 bottles indicating compliance. Do you think all Mobil 1 5W20 is now in compliance?
