To save about $1.50 you risk expensive engine damage. Pretty good deal.I use Castrol 5w 30 Motorcycle oil. Cheaper than the Honda oil. Whatever you use, just be sure its wet clutch approved. I even use a 1/4 bottle of Lucas at oil change.
Honda Oil around here is about 3.50 a bottle. I don't save but at the most fifty or maybe 75 cents a quart. Depending on how often you change your oil you just dont save all that much. I doubt honda makes their own oil. I am sure they have it blended to their specs by a major company and I am sure some of the other oils are as good. All I am saying is you dont save but maybe $8 a year by using cheaper oil.Any idea who makes the "Honda Oil" ? Or do you think Honda makes there own? Think about it. Not saying Castrol makes it but you can bet your ass a major manufacturer does. What do you think is in your bike for an engine? Something that was meant for F1 ? Its a MotorCycle engine. I'd say your pretty safe with a major brand of oil that is wet clutch approved. $8 a bottle for the Honda name or $3 a bottle at Walmart for the same stuff.
There again you prove my point. A slight increase in cost per quart isn't all that much in overall cost, and it gives you piece of mind.I've been running Amsoil 10W40 synthetic (MCF-01) in both my bikes since first oil change. Love the stuff. Some say a little pricey, but IMHO well worth it. It does cost more per quart that other oils, but the drain interval is extended w/ Amsoil, making the price difference even out. Pay a little now or a lot later.
