My Mini Z has just reached the 5 hours mark. I read in the Owner's Manual to perform the initial change Oil after 5 hours of operations. My question is do I need to change the oil filter as well? The Hustler Owner's Manual did not mention anything about changing the oil filter during initial oil change. The Engine Manual did say to change the oil filter every 200 hours of operation. Just want to make sure I am doing the right thing to protect the engine. Also what brand of 10W30 oil do you recommend? Thanks in advance.
