I bought my 2019 Chieftain last week and already rolled up 500 miles. I changed the oil today and put 5.5 quarts in the bike along with a new filter and the oil level on the dip stick is not even close to the normal range. The bike is level and I ran it for three minutes at 2000 rpm but the oil level still lacks about a half inch from the normal range. The owners manual says 5.5 quarts which is what came in the kit but it is low according to the dip stick. The oil bottles were all full but they do not specify an oil weight on any of them. What weight oil is required? Do I add more oil to bring it up to the normal line on the dip stick or leave it with the 5.5 quarts and call it a day?
