If the oil change indicator doesn't come on before I change the oil, will the system know that the oil has been changed? Or, does the tech just reset it?

BY OCD, do you mean Oil Changed Daily?
I meant *obsessive compulsive disorder* of course, but *oil changed daily* also fits the description LOL.

About the oil life indicator system and oil *quality* : auto engineers (and all engineers) always implement such systems with a margin for error, or a safety margin depending on the system - or how you look at it. There are a bunch of sensors on our Jeeps and this system uses those sensors to determine driving environment and driver habits. Oil life is calculated in an ongoing fashion, depending on input from these sensors. In *normal* conditions, oil life in our engines is 10K miles or one year. And the engineers know we can use conventional oil, so this 10K life can be extended for semi and more for full synthetic, though they don't say in the book. The one year limit is a safety thing for those who don't put many miles on their vehicules, to prevent one oil fill from staying in the crankcase too long and degrade over time. I use full synthetic and wouldn't be worried about changing it at 15K miles if I lived in a warmer climate. I wouldn't do it because of possible warranty issues though, I just know the oil would still be *good*.

And yes the oil life indicator needs to be reset manually (easy to do, it's in the manual as shown above).

Is this system perfect ? No system is, but like I said... it was built with a margin / safety factor, so even when it nags at 5% oil life, you don't have to stop in the middle of the espressway to change your oil

Take a leap of faith, run that oil to 10 or 20% on the monitor. Then order up a test kit from Blackstone Labs. You'll very likely discover that changing it at 60% is a waste of... everything.

As for brand... I'd use whatever major brand synthetic is on sale. Mobil 1, Valvoline Synpower, Pennzoil Ultra or whatever they call it now, etc. Maybe get one that is actually MS-6395 stamped if you want. They're all the same type of group 3 "synthetic", aka super-refined top quality dino oil. Unless you're into expensive group 4 or 5 oils like Amsoil or Redline, brand just isn't going to matter much.

For my first and previous oil change, I decided to just stick with the recommended stuff, and used Pennzoil Platinum 5W-20 synthetic. I might consider going with Mobil-1 at some point, especially if there are nice sales going on at Costco, but for now, I'll stick with Pennzoil Plat. for now.

I'm currently at around 5700 miles since my last change, and the indicator is at around 20% or so (lots of city driving this time around), so I'll be changing it probably sometime next month, unless I decide to change it before my trip to the Isle of Man next month. We'll see.

Penzoil Platinum is what I use, because I can buy it on special all year, usually at or below what Mobil One costs (on special). I doubt one is much better than the other, frankly, fanboyism aside, and knowing we don't drive 400K+ miles with one car, usually... For the VW I'll buy Castrol Edge because it is the only one with the recommended VW spec, and I can find it on special all year too.

Once the indicator gets to 10% oil life left, it dips to 5% rather quickly ( like a week or two) and then it nags you on every startup.

Going OT here, but yes, IOM TT this year. Was last there in 2013 with my family, and extended family (SIL's parents who live there), and we're going back again next month. Can't wait to get back, and also hopefully get back my photography spark that has left me for the last couple of years. I took thousands of photos that year, and I was so proud I did that. Lately, I haven't had as much interest in photography as I once did, so I'm hoping it'll come back. Maybe I just needed a break from it is all.

I'll likely make a thread on the JCC Lounge detailing the trip.

Ah lucky you... Some day I'd love to go there and watch a bit of the TT race. One of the forum mods went last year but just after the race I think.

Yes pics please ! It's gorgeous scenery, and those bikes... Try not to be like this guy in the video (beginning), trying to film bikes going 200mph two feet from his face lol :

Lucky you !! Yeah I said that already, but... Enjoy...

You couldn't pay me to do that! That's crazy though, I'll forever be wary over the new additives they put in oil. I'm just old school i guess.

FCA dealerships usually get their oil in bulk, and they get Penzoil only because of the FCA/Shell partnership. All stocked Mopar oil is Penzoil. Smaller dealerships like mine only carry a few conventional oils in bulk, so synthetic is jugs (of Penzoil). Big dealerships have everything (or most everything) in bulk, including Penzoil Platinum (synthetic).

I wouldn't do that, to be honest. In ideal conditions (moderate climate, highway driving at/near legal limits with little stop-and-go, clean air, light engine loads, good gas, etc...) the engine likely won't suffer any damage with synthetic oil for 18K miles. But what about the powertrain warranty vs required maintenance ? What about possible long term effects of wear and tear from doing those 18K miles in less than ideal conditions, with badly degraded oil at the end of the stint ? No thanks... and I really don't see the why anybody would do that, unless you are gathering data for FCA and don't need to care about engine longevity and/or warranty limitations,
