Floridians favorite vacation fantasy?... “I’m gone skying in Colorado, baby”...Flatness to madness!
Let’s go back to high oil temps.
Yes but that”s why sumps contain 5,6,7,8 quarts to help bring the temp back down. Take the Chevy LS engine in the 2020 Silverado. It specs 0w20, and has an 8 quart system. The pickup screen takes the oil where it is sucked up to the oil pump, through the oil filter, up as high as the heads where some of the oil covers the rockers, some goes to the cam and some goes down to the crank and rod bearings, and THEN some of it is exposed to the piston and combustion chamber walls. The bulk of the oil is at just over 212 degrees F normally. The oil passes across the hot journals and cylinder in micro seconds and falls back in the pan. Also if the engine is equipped with an oil cooler in the rad, it will help keep the temp as close as possible 212 F. At high rpms like with track use or high turbo temps experienced while going up mountains, the temp rises and the viscosity drops significantly. If you do this a lot and believe a higher viscosity decreases wear, then you might want to go up a grade ( don’t mind the pun). I routinely drive a road that climbs 2500 ft in 20 miles. If I had a turbo, it would be working.Look up internal engine temps - pistons can see 600F, conrods 475 at the top and 300 at the crank... oil is getting up in all that. There’s a lot more going on in there than we realize. You haven’t hurt your oil at all. Run it and enjoy.

Whoops. Search “oil temperature” but without your name. That will grab posts from others. Good choice on the oil.Yes, you probably would be correct on that, it will be cooler, but not cooler than the water temp in the rad. Since Mercedes has given the OK essentially of using a xw40 oil I would recommend choosing one of them. If you use the search function in this forum, with your name and words “oil temperature” you will be able to see posts about other folks experience with oil temperature issues. Good luck. PS, I’ve been to Greece twice. Wonderful country and people.
