Engines are being built to tighter tolerances. Thicker oils don't flow into the nooks and crannies as well to properly lubricate everything that need slickened up.
Wife's 2015 Subaru specs 0w20 Mobil 1. 60k miles later, no issues. Seems to work. I have a '16 F150 3.5L with a pair of little turbos, about the size of my fist. Engine diagnostics tell me when to change the oil, averaging around 10k miles. Still getting used to both of these developments. Both vehicles getting better milage than I experienced with similar iron back during the 80's and 90's. Both seem to be aging better as well. Both sure cost a hell of a lot more.
Imagine your grave on a windy winter night. You've been dead for 70 years. It's been 50 since a visitor last paused at your tombstone..... Now explain why you're in a pissy mood today.

Yes . Very quick way to void warranty and new equipment cars and trucks is to run to heavy oil
Actually............WD-40 is a fantastic starting fluid for diesels. Unlike ether, because it's made mostly of kerosene it ignites when it's supposed to without the premature detonation you get with ether. Plus you have the added benefit of a little upper cylinder lubrication that you don't get from ether.

WD40 is a cleaner. It's not really a lubricant. It's great for cleaning out trailer light plugs. Truckers use it all the time when the lights don't work right.

It's not over when you lose. It's over when you quit.
Another reason why they're going to thinner oils is to help meet EPA mileage standards. Thinner oil means higher gas mileage.
That';s mostly it, the topend of engine life will be reduced. Tight tolerances create more heat and throw in turbos and it gets worse. It makes car maintenance even more important.

this ^^^' as well as thinner oils will circulate faster and dissipate heat more efficiently.

Yes, years ago I sat next to a shearing plant engine as it flew to pieces because the property workers sprayed too much Aerostart into it...I sat there and enjoyed every damned moment of it as metal flew past my ears.

Not just for diesels, it is a fantastic starting fluid for gas engines too!

WD40 is a solvent and works pretty well for that. It also makes a good coolant for machining aluminum. Other than that it will gum up your mechanisms when it dries, so it's not so good as a lubricant.
