It says on the s&s x wedge manual. Section 6 page 2.
I paraphrase:
Do not test the oil level if the engine has not been run in the last 30 mins.
run the engine for at least 1 min then turn it off for 30 seconds to check the oil level.
(Keep the oil cap on while the engine is running and remember yo check the state of the oil cap seal... but you know that already)
