Question Oil recommendation for 2015 GC - V6 3.6L Pentastar engine

I've searched the forums tirelessly to find a definitive answer on this, but am still looking for confirmation since there's so many different GC engine types.

I have a 2015 GC with the V6 3.6L Pentastar engine. Am nearing 3000 mi and want to prep for my first oil change. I own the car, and plan to own it for a long time so want to keep the engine in good shape.

The manual says the following : We recommend you use API Certified SAE 5W-20 Engine Oil, meeting the requirements of FCA US Material Standard MS-6395 such as MOPAR, Pennzoil, and Shell Helix.

However, upon reading these and other forums, I find most GC owners use a semisynthetic or full synthetic like the Pennzoil Ultra Platinum 5W-20. I was going to go with a standard SAE oil like Pennzoil SAE 5W-20 API, until seeing many owners using synthetics. Is it safe to use a synthetic oil on this engine?

I don't want to start a fight about which oil is best, etc etc, but if there's sound reason to go with the synthetic to promote longevity of the engine, better MPG, etc...would love to hear it.

Read some where that you should keep the factory oil in a bit longer (its some special oil). Could be 9000 km, but just double check.

Regarding oil: been using Penzoil Plat. 5w-20 Synthetic and haven't looked back. I change it at 10,000 km (the oil indicator usually says I'm at 30% when I do). Its colder climate here.

I have been using Penzoil Platinum Synthetic 5w-20 because it is cheap a Walmart, $22.47 this week for 5 quart jug.
I run mine to about 80-90% on the oil life monitor which is usually 7.5k miles.
I had a blackstone labs oil analysis done a while back and they suggested going closer to 9k miles.

There's a TON of threads about this very topic...it's quite common. I personally changed mine at 5k miles (once/year since then) and exclusively use Amsoil Signature Series (full synthetic) for everything.

I use regular Pennzoil and change every 5,000 miles. Changing synthetic at 5,000 is pouring money down the drain.

In my experience, as long as you aren't using "discount" oil...changing it often is more important than what you're changing. As long as it meets the minimum requirements, you can use anything.

I did my 1st oil change @ 3000 miles using "Regular" Pennzoil 5W20 to help seat things in. Next Oil change @ 6000 using Pennzoil Platinum 5W20. Will change out every fall and spring going forward regardless of mileage. I'm sure I'll be way early going by Oil Life Monitor.

I called for an appointment 2 days ago for my first oil change. My oil gauge still says 17% and I'm at 8,300 miles. The Service Advisor basically read me the riot act for not being in sooner. I told him the manual says 10,000 he said I was wrong. I read the manual and as long as I don't drive in dusty conditions or pull a trailer (severe service) I don't need to be in before 10,000. He backed down after pulling up the manual. In Appleton, WI its $69.95 cost for full synthetic. Overall seems pretty reasonable to me. This service advisor has me worried.

I plan to use Pennzoil Gold 5W20 (synthetic blend) every time there is 25% remaining. Should be about every 5000 miles or so.

Looked into this a bit more, seems it is special oil from the factory, but no mention of keeping it in longer.

Page 108 of my 2014 JGC owners manual.

"The engine oil installed in the engine at the factory is a
high-quality energy conserving type lubricant. Oil changes
should be consistent with anticipated climate conditions
under which vehicle operations will occur."

Since my other two vehicles require synthetic oil, it's easier to also use it in the GC. However, it's not required. I switched over from the factory fill at just 1,000 miles and it hasn't grenaded itself yet. 😊

LOL

Chrysler has had that description in their owners manual dating back to 1985. Nothing special about the factory fill oil, cheapest bulk oil they can find meeting their spec. In early 90's Chrysler paid 7 cents
per qt at factory to fill the engines, this from their head reliability engineer.

I personally dump factory fill early to get initial wear metals out.
Dump a few times at 2k and then run sythetic of your choice meeting the spec.

It is absolutely safe to use synthetic in your 3.6 engine. Now, whether or not you want to spend the extra money? You can read thousands of pages online about the merits (or not) of synthetic oil.

Synthetic is cheap insurance... Synthetic is not an issue in any Jeep.

Synthetic offers support high temp protection ( like a water pump failure).

I use Mobil 1 in all my rigs... Cars, trucks, boats, motorcycles....
