I bought a DD early in August. Last week on the way home I was trying to find something on the iPad sized screen, hit something, and oil temperature readout popped up. Never had one on a vehicle before. On my way home, outside temps last week were 62/63. Same as this morning. I changed the oil on Thursday to Mobil 1. Last week (only the one morning driving home) oil temp was 210-212. This morning 201-203. Always wondered if it did actually reduce friction. Guess it does. Oh, it had a dealer installed oil filter, so assume they used the recommended weight the factory calls for. I just used it on synthetic.
This is a 2020, two of my daughter have 2019’s from the same manufacturer, they don’t specify Synthetic oil, just the weight. But even so if synthetic , M1 is doing something theirs isn’t.

I run Mobil 1 Full Synthetic "High Mileage" in everything I have, old & new. I can see a vast difference in how clear the oil is when draining, compared to conventional oils. I've seen better oil pressures & lower oil temperatures than previously ran conventional oils (used to be a die hard VR-1 guy).
That’s why I titled the post like I did. I have to find the other screen on the thing, but we’ll be cooling off soon so won’t be much apples to apples (mine anyways) comparisons. I just thought it interesting and something I never had seen first hand.
My dailies have always been sauerkrauts. Because of the turbos the warranty is void if they can prove you don't use synthetic oil. I use Mobil 1. Last summer went on a 5600 mile vacation, used about a quart total. This summer I switched to the " German blend" and it used NO oil. The claim is the German blend is better for higher temps and won't coke up the turbo.
If I could use any brand of synthetic I would use Amsoil, and in my Harley I do. In my daily drivers I’ve always used Castrol but I’m sure Mobil 1 and a couple others are just as good if not better. My older hot rods all run Lucas Hot Rod oil, mainly because I don’t want to chase leaks. A quick story about synthetics versus conventional oil. My Dad worked at a large cemetery after retiring from his 40+ year job. His job was maintenance of all the equipment. He said they had people out mowing on a hot afternoon (larger air cooled engines), and when they came back in for lunch he could hear a bubbling noise out in the lot. He went out to investigate and it turned out to be the conventional oil boiling in the crankcase of the recently shut off engine. They’d already lost a few engines that summer so he switched them all over to synthetic and he said he noticed a difference immediately in regard to how hot they ran and the way the oil looked on changes.
