Took Rhino hunting in very cold climate. Got cold last night (snowed) and next morning checked oil (after driving) and oil looked gray. Could this be from the cold weather and getting engine up to operating temperature. Antifreeze was good to -24. Not sure how cold it got by probably not below 20 - 25 (above).
Any ideas?

The only time I have seen grey/gray oil is when it was black and turned grey after water/anti-freeze got in the engine. Was there water drops at the top of the dipstick?

I didn't see it myself. But said Rhino was covered with snow. Anyway it could have been sucked in through air filter?

Reading some info online, it may just be condensation from being so cold. Start the rhino let it run, or drive it around for about 10-15 minutes then check it again if its still gray then you've got a head gasket leaking, check your coolant level is it low?

This is what I am hoping as well. I have not seen Rhino yet. But if it is head gasket then coolant should be low as you said. And would coolant start to turn murky from oil be sucked into radiator???

When this happened did it look grey on the dipstick.
I am seeing it for 1st time after this happened and it looks fine on the dipstick. This is a Week later.
Wondering of I should still change oil.

If left untouched for some time eventually the antifreeze would turn a murky color too once its circulated through the system a while. Once that happens though your engine is pretty much toast due to the lack of proper cooling and lubrication. Your engine will also be burning coolant so its going to foul up your spark plug too.
