This may sound like a dumb question, but how do you change your oil?
My riding buddy says he drains his then adds 2 quarts and drains it again. Then he refills and goes riding.
I was looking into the Scavenger type of oil changer. What do you think?

I go for a ride to warm the oil up and change it while it is still hot. I believe all the particles and contaminants will be in suspension and drain out. I've heard of a 5 qt oil change but have never done it. Tim

 

I ride for 5-10 miles to warm things up, put my RK on a jack and start pulling the plugs. simple job. I wouldn't waste the other 2 quarts unless I was trying to flush out something. I don't know what that would be though. Get a shop manual and follow the instructions.

 

I got the scavenger system for Christmas but have not used it yet. Probably overkill but I intend on riding this bike a LONG time and can't see leaving dirty oil in the system while adding new clean oil. For those who say it does not matter, where do you draw the line? Why not just change 1/2 your oil? I don't like the idea of diluting my new oil with used oil. It was recommended to me by a wrench on these forums. If anything it makes me and the bike feel good. Ride safe.

 

If it makes you feel good, do it. I don't think that there is enough dirty oil in the system to dilute the fresh oil IF you warm the bike up and let it quit dripping before you put the plugs back in.

I own a scavenger and the shop has one too. I recommend it. You will get almost an extra quart of dirty oil out of your engine by using that device. People dont realize that alot of dirty oil sits in the cam chest and cranskshaft cavity, and valvetrain when they do an oil change. Worth the $50 IMO.

 

That's a pretty slick tool. I might consider it.

According to the published literature, the new dyna's don't have any external oil lines. Is that true? If so, I think you'de have to make some kind of fitting for the oil filter boss. But since the oil flows from the pump to the filter, that probably wouldn't accomplish anything significant.

 

Thanks for all inputs. I'm gonna order one of the scavenger units.

 

I ordered mine today! It really looks like the best way to chaing oil.

 

Bob, take a look at the video for the 88A model. They are hidden behind a cover in some cases. The lines are real short and a special elbow is installed with an inline disconnect. It looks like a pretty good idea when you see how much extra dirty oil you would remove.

Group Buy anyone?

I'll take a Twin-Cam 88A.
