There is a universal dipstick available, if you don't have another correct dipstick to compare it to, then dump and refill the crankcase one quart shy of capacity and mark that level as the add mark, then put the rest in and mark it again as the full mark. https://www.google.com/shopping/product ...

Manual states 4.5 qts, but I thought there was a lot of discussion on this site that the manual wasn't correct. I filled it to just a hair over 4qts and plan on keeping an eye on it. I'll get the correct dipstick and use that fill level for the future.
