Hi All,

I find this hard to believe but need to verify, I bought my Challenger 1320 last year on Sept 11th. I drove for a few miles and have parked it for the winter started on nice days and got to temp of course. So I get an email from Dealership that it is time for an oil change, the car has 1300 miles on it. I think it is to soon but i also don't know if there is break in oil in it or is it good for 3000 miles? I did call the service manager and he said I should bring it in because oil gets old?? Need some advise all my other cars get oil changed at 5000 miles according to service records and manual. I have not opened up the manual because i want to keep things preserved as delivered best i can.

what say you??

3niner2 .... consider yourself into THE LOOP of the most expensive oil change “circus” that FCA has invented !

6 months or 6000 miles .... whichever occurs FIRST !

The reason ? ... ... even the at the SRT contact at FCA doesn’t know ! And REMEMBER... the SRT cars require a special spec 0-40 oil ... 12633 ...IIRC.

Maybe .... because of special piston cooling needs and/or the HP nature of the engines PLUS them having MDS.

There’s a guy here ... mopJ ? ... who said he did a deep investigation of this situation.... I’d like to know the exact reasoning behind these requirements......

These SRT engineers certainly are more knowledgeable than I am ...

my 6.4 SRT8 in my 2011 ram would not quit ticking until I put in 5-40 Mobile one synthetic. I never seen an engine so picky about the exact kind of oil it had in the crank case butt luckily it ain't too expensive to buy at wal mart and do it myself.

Let me add Niner .....

That service MANAGER ? ... is incompetent and should be fired .....

What he said in purely dishonesty

Its just a marketing deal, they want you to come in. They would have sent that if you had driven 1300 or 13000 miles. It likely has zero to do with your actual oil change interval and its just a timed reminder automatically sent out.

That oil change interval IS THE RULES ... I understand that ....

But for that to flat out lie in this case with claiming the oil gets old ....

Shame on him

No, the oil don't get old (well technically it gets older just like everything but does not degrade significantly without being used) , the issue that can demand some people get oil changes at very low miles and long amounts of times is how that mileage was put on the car, was that 1300 miles put on 1/4 mile at a time with a complete cool down between every run? Grandma driving down the block for groceries in the winter without ever warming the engine up? That can add lots of contaminates (mostly condenstion) into the oil that can result in sludge witch would necessitate more frequent oil changes, or did you drive it one time on a 1300 mile round trip? In that case there is probably no discernable difference in the ability of the oil to properly cool and lubricate your engine parts. They probably are assuming lots of short trips without warming the engine if you have very low miles after 6 months witch could be valid point or completely off.

and mobile 1 extended perf. says 15,000 miles. backed by a warranty ................. full syn. is min 7000 miles... but if the dealer is covering the warranty, they get the call !

.... so Mobil1 has an engine warranty on a 15k change cycle ?

NOW ... from what I’ve been told ... there are only two major brand oils with that 12633 spec ...

V and P ...

Why is it frequently called "mobile" (sic)??

I get what you guys are saying. I would guess the trips taken to get to 1300 miles were about 100 miles at a time give or take. yes I made a few hot shots down m59 and another side road i live off of but not all at full throttle. my average speed on the freeway was 80 with an exception of a few foot to the floor from 80 to 110 on the freeway, the car has been treated like a creampuff. I will bight the bullet and get the oil changed to keep all warranty folks happy and within the guidelines of what needs to happen. I will have this car for a very long time so it needs to be treated very well. As i like to say jokingly, its only money i will make more.(sooner or later)

thanks guys and if anyone gets the answer to the deep dive of why feel free to add it in here i am interested in the answer

So that people can point it out on the internet.

i did not know they had a 20,000 mile oil !!! https://www.mobil.com/en/lubricants...msclkid=e856110e1d9a1bf74d32715f0f10ea9a

Pretty sure back in the 70-80’s it was touted as 25,000 mile oil.

In the 70 and 80s ... so my grandpa told me ... the way those motors leaked (aka blowby) ... the oil in the pan after 25,000 miles would be 50% gasoline!

Speaking of oil changes....why the heck do the different hemis have different requirements (my 5.7 vs 6.4bge)? My 6.4 makes all sorts of weird noises with the 0-40 vs my 5.7 were you can just hear the injectors.

[spoiler][/spoiler]

What specific oil are you using in the 6.4 ?

THOSE require that 12633 spec oil

The 6.4 engine is built with very tight tolerances, the 5.7 is a "looser" engine. There is a ton at play when the manufacturers designate an oil and weight. They have to check all the boxes, not just 1 or 2. So they shoot for all around decent oil, where if you find a brand and weight that works in your engine, you may leave a little on the table in some areas, and gain in others.

These engines should have never been designed with MDS, thats my opinion. Many will argue the mileage difference, but I DID do many real world tests in the last charger I had (5 speed), the mileage was within 1 mile TOTAL round trip between MDS ECO MODE on and with it turned off.

If your hearing strange noises, pin point it before a problem gets away from you. Yes, the injectors can be loud, but know the difference between them and clack lifters and/or exhaust leaks.

Mobile One

Being a tighter engine would be my assumptions as well, as the oil requirements would believe me to think.

My 18 Powerwagon and 12 Durango have the exact same lifters (5.7 was updated with cam swap). For example if I just move my PW around in my driveway and it doesn't warm up before shutting down the lifters will rattle next time for a few seconds as they pump up (truck has 22k on it). The Durango never does this and in normal driving situations the 18 doesn't either. My assumption is the heavier oil . This is more of an observation, I do not think there is a problem of any sorts.

Looking back I wish I would have deleted the MDS on the Durango but that thing actually uses it a bunch when on the freeway compared to my PW.
