Not sure what oil costs there but I feel the per month cost of oil is dirt cheap (even Amsoil or Red Line). I always dump it after one year if on a low mile bike. I don't care what the TBN is. What is the cost of an oil change divided by 12 months in a per month perspective? Nothing, nada. Do a little quality time with the machine and dump it. Send the used oil to those that that think you shouldn't so they can use it for something. Oil is cheap, engines, trannys, and clutches (shared sump right?) are not.
Very well said! I put about 2000mi a year on my 2001 HD Road King Classic and change all 3 holes every year with Amsoil products. 20W50 in crankcase/10W40 in Primary/Severe Gear 75W90 in my Tranny. Also use an Amsoil 134C EAO oil filter. I think the cost of these products, around 55-60 dollars, is cheap considering the money invested in the Bike. I do it myself obviously. I think a dealer charges around $150.00 for this service using regular HD Dino oil.
