Was advised to wait for after 3 changes by a fairly informed guy, let the standard oil work out the small particals & filings then it will be ready for Mobil 1 or your favorite brand.....The Amsoil is very good too.

There is absolutely no science behind your friend's theory.

True, and the differences between the various synthetics are so minimal as to be insignificant. Amsoil is great, so is Redline, Mobil 1 is cheaper.
 
Thinking about doing it on the first change. Any good reasons why not?
Depends on what your plan is. I did a couple of changes on short intervals to remove all the metal shavings. Then I switched to synthetic. Figured why waste the extra $ on switching when I knew I was going to be changing early.

Otherwise I would have switched at the first change.

Oil is oil. It all comes from the earth......right? Now synthetics I have not a clue what sorta chemicals are going in there.
Haha I grew up in a western PA town called Oil City. You'd think that I would know a little bit more about oil right? Only ran Pennzoil or Quakerstate due to the hometown link. Last vehicle I drove's engine sludged up at 100300 miles :facepalm: after an oil change I did not too long before with Pennzoil :hide: or perhaps it was because I was driving a ford exploder. Going to try M1 syn at 700 miles tonight before a 800 mile trip this weekend.
 
This for information only, I do not wish to (and will not) start a discussion on this.

I noticed several posters indicating they were planning on switching to Mobil 1. For 2012 models this oil is not approved. The owner's manual indicates that:

"… the manufacturer recommends engine oils that are API Certified and meet the requirements of Chrysler Material Standard MS-6395."

Mobil 1 does not list this on their spec sheet; from my understanding the reason Mobil products are no longer 'approved' is due to the Chrysler bailout where Chrysler stiffed Mobil out of quite a bit of money. The 'approved' oil is now Pennzoil, so you are left with the Pennzoil synthetics. I bring this up since Chrysler has a little reputation about their warranty.

Like I said, this is just for information; it’s free, so you got your money’s worth.

So they created a "standard" based on their business relationship with the company and not on the actual quality of the material. They should change MS-6395 to BS-6395 then. :D

Thanks for the free info
 
I will go dino till maybe 3,000 and then switch to Valvoline DuraBlend. If I switch to syn, I'll go Pennzoil Ultra though since I plan on short oil changes in the Jeep, I may stick with DuraBlend.

I agree. I've been through this oil BS so much with Harleys that I will side with the rugger......if you don't understand the corporate BS, it's not worth discussing.

Or Amsoil:

GF-4...; ACEA A1/B1; Ford WSS-M2C946-A, WSS-M2C929-A,
Chrysler MS-6395; GM dexos1TM (supersedes LL-A-025, 6094M
and 4718M). Fortified with detergents that exceed dexos1™ sufated ash specifications.
 
The guy I bought my jeep from said he's been using synthetic oil since he bought it from its original owner...at first I was mad because i like my conventional oil but then again synthetic oil is made in an actual lab with those big brained scientists, nothing natural about synthetic, they have a superior molecular construction which eliminate things like sludge and oil sheer. I know that if your engine has 50k+ on it and isnt on synthetic theres virtually no space between the piston ring and cylinder wall and thats the space where those molecular structures come in and start mowing down the shi*. use them before you put 10k on your engine or just dont use it all.
 
I have a 2010 Rubicon and it has never seen anything but Mobil1. Off the lot with 7 miles on it, the change oil went off at 2100 miles and since then it's been synthetic. I don't know how the oil change indicator works with those using regular motor oil, but I average about 5400 miles before it goes off.
 
Switched the 2011 at 7500 miles(2nd change) and the 2012 at 3000 miles(1st change).

Been having some issues with the 2012, but suspect that the Dealer screwed the oil weight up and then tried to cover it up. We'll find out for sure in another 1000 miles if the incorrect weight oil is the culprit.
