New Ariens 24 Platinum Sho

My first snow thrower on the way, just ordered.

Hearing I should pull wheels first thing, add some grease and a good coating of anti-seize.

Run the break-in oil from factory for 4-5 hours then drop it for new oil. Should I go straight to a full synthetic like Amsoil Small engine?

Guessing 5w-30 for storage and use in Colorado where weather fluctuates a ton is ok?

Any other tips y'all have.

Thanks boys!
