Checking oil, warm or cold?

[rdfish1]

I read something here that said start the engine for 30 sec then off for 30 sec and ck oil on 4tec 155. I did this and found the oil was at the bottom of the hash mark. Interestingly, I checked it before I ever started it, totally cold, and the oil level was 2/3 up the hash, basically perfect. What is the proper way to ck.

Also, I want to ride tomorrow and may need to add a little oil. Dealer is closed, what kind of oil from autozone will be compatible with the dealership oil in there now? Thank you

Can't answer the other questions but I wouldn't be mixing different oils.

Figured out why the oil was low. While my trailer and ski looked level, it was not. I put a small level on the motor and realized it was way to high. After adjusting, the oil level was perfect, just past half.

Ran engine on the hose for 2-3 minutes, let it rest for 1 minute and checked it.

Regarding oil, mine calls for 5/40 synthetic but seems like many run 10/40
