I see in the manual for my 2022 P520 that it recommends 10W-30 oil, but that 10W-40 is also acceptable for my local climate.
Under what circumstances would I want to use 10W-40 rather than 10W-30?
It seldom sees a high speed run (maybe an occasional run down to the mailbox a mile away, but that is rare, since they are not legal on roads here.) 90+% of the time it is low speed: below 15 MPH with occasional runs up to 20 or 25MPH. I use it year round, plowing the driveway in the winter, and working in the woods year round (sometime hauling a 1000# trailer of firewood). I'm in Vermont, so only rarely see temperatures in the 90s F (and tend not to be out working in that temperature if I can avoid it). It's sometimes used in 10˚F and rarely lower weather, but stored in a +/-45˚ drive-out basement of my shop, so it does not tend to see many really cold starts.
Given my use and my climate, I'm thinking no reason to switch to something other than 10W-30. Is there any reason to reconsider?
NOTE: I'm well aware of the TYPE of oil recommended for use in the engine/DCT. I really don't want to get in to another "Oil Wars" debate on dino vs synthetic or various additives to look for or avoid. My question is purely a viscosity one: 10W-30 vs 10W-40 (or other viscosity).
