Its time for my 5K service and I thought I'd do it myself this time and save some $$$$$. Was going to change the fluids in all 3 holes so I bought Mobil1 V-Twin 20W-50 full syn for the motor, Redline Shockproof Heavy for the tranny, and HD Formula+ for the primary. New O-rings, gasket for the derby cover, and new oil filter. Reading my owners manual and my brand new service manual ($60), the scheduled intervals for the motor oil is every 5K. But the tranny says every 20K and the primary 10K. Should I save the new fluids, (other than the motor oil) and wait until then, or just go ahead and change them all now??? I know it can't hurt anything to change it all now, but am I just spending time and money on doing it when I don't need to??? Wondering if the dealer would change all fluids if I had them do the 5K service. I would hope so for $350. Also the dealer said the primary takes 1 qt. but the service manual says 38 ounces wet, 45 oz. dry. Should I just put in 1 qt. or buy another bottle and put in the full 38 ounces??? Thanks.
