    Use any oil that meets the spec in your owners manual. I've used "car" oil in all my bikes for years. Wet clutch and dry and I've never had a problem except I've saved a crap load of money. But many will tell you that if there isn't a picture of a motorcycle on it and it doesn't cost twice as much you will die in a fiery engine explosion...

    I use Rotella in all my motorcycles and atv. It is a diesel oil, which generally holds up better on schear forces, plus it is motorcycle certified.

    ... then your engine will probably sell destruct and require a rebuild after only 25k. :rofl

    2 Reasons, it makes it easier to remove the next time and prevents O-ring failure. The o ring will be dry and "could" freeze to the surrounding metal. It can cause the o-ring to stick to the filter or engine case and make it a lot harder to remove the filter the next time. I had a friend have this happen to his boat. Once he finally got the filter off (which was apparently a PITA), he didn't check for the old o-ring. It was stuck up on the engine where he couldn't see. He put a new filter on with a new o-ring, which then resulted in the new o-ring AND the old (or whatever was left of the old) o-ring being between the filter and engine. Ended up blowing out one of the o-rings, lost all the oil and seized the engine.

    Regardless of the engine type, I've always checked to make sure the entire old o-ring comes out and that the new one goes on correctly and is lubricated with oil. Its probably just going the extra mile and won't always cause failures, but not a lot of extra work.

    At risk of putting words in his mouth, I think he was asking what happens if he doesn't use NEW oil like Flashdog suggested. The OLD oil works fine for lubing the O-ring. If the oil coming out of your engine isn't good enough to lube the O-ring, it should have been changed LONG ago.

    Agreed. Maybe subconsciously I just wanted to share my own 2nd hand horror story. :smile6

    Don't get me wrong I do it every time...... just never bothered with coating it in new oil.... working at a dealership I've had days where I'll do a dozen oil changes in one day and the process involves draining the oil. new filter and then grab the jug of new oil before filling the bike. So old oil is just fine to coat the new filter ring

    Maybe I should do the same, I did it my myself and it cost me about $45 (3 quarts of Mobil 1 Synthetic motorcycle oil at 10 bucks each + 1 BMW oil filter at 13 bucks each + sale taxes)

    Yeah, I'm sure its fine. Whichever is easier to reach. Actually, I think I use new oil because old habits die hard from working on cars. But I once lost a quart of new oil cause I opened it to coat the o ring, set the quart down without putting the lid back on, put the filter back on the engine and promptly knocked over the quart of new oil. Wouldn't have happened if I had used old oil on the filter and opened up the new quart when I was putting it in the engine. That or put the lid back on. :puke1

    And on top of the $39 you spend for watching the tech watch the oil drip out of your bike, what does he charge you for the filter and the oil?
    Or does that price include the filter and the oil?

    You could pick up a little crud from around the hole (leave it alone!) and that may interfere with a good seal.
