Dont run an oil temp gauge lol

Dont run a gauge either but its usally close to water temp in my peterbuilt
-
Over 200° under 250°F
FWIW, the viscosity rating on the bottle is at 212°F. The "W" rating is winter and is 0°F.
Just a little tidbit of useless knowledge.

GT so it's safe to say that 225ish would be ideal.

GT I know this is a different topic but what is ideal water temp in a jet boat on the River? Thanks again in advance, we appreciate all your help and knowledge. You rock!

Thats where I come from. Large car.
281, NHE 262, (T-590) 5x4, water temp 170, oil temp 185-190. Don't lean on the Luber-finer either, lol Since 1959.

Not exactly, but close.
20W 50:
20 weight stock (20 weight oil)
at temp, (212*F) acts like 50 weight stock. (similar viscosity)

"W" stands for winter.
"W" not used in straight weight oil.
Straight weight oil is rated at 212°F.
"W" weight is at 0°F.
Polymers are used to modify the temperature glide. Which can favor the cold or the hot side of things.

I'll agree to disagree.

I'll just leave this here.

It's a little more convoluted than that.
250°F being the max, doesn't necessarily mean run it at 250°F, it means for short bursts, 250 is totally acceptable.
You want to be above 200 for the simple reason that the warmer temperature will boil out harmful water, this reduces the formation of rust (affectionately called iron oxide).
So if I had to pick a perfect temperature out of a hat, I would hope to pick 215°F
No water and long oil life.
This assumes the correct weight oil was chosen from the get.
The colder the oil, the lower viscosity number should be chosen.
Being as a multi viscosity oil has a 212°F spread from hot to cold, a multi-vis oil is not really necessary in our stuff, as an estimated example, if you boat at 95°F air temperature and use 20W-50 oil, the temperature spread drops to 117°F, if you are still with me, the oil is really closer to 35W-50, but has bunch of polymers to modify the final viscosity that aren't being utilized and reduce oil effectiveness.
Just food for thought.

And just so it's said.
The actual oil temp can be over 100°F warmer than the water temp.

All good info!!! I am pretty sure my oil is quite a bit hotter than my water temp
-
oil temp??? whats that???
Ive never seen past 180 lol

We had a small block marathon boat than ran pretty damn hard.
I was shocked when we returned to the launch ramp and the paint had all burned off the oil pan.

Yeah I think the 10 quarts helps a bit too
