Might be worth reviewing this old thread to refresh your memory: Scavenger Oil Change Questions - Harley Davidson Community I used a bit of my Christmas $$$ several months ago and bought myself the Rogue Chopper Scavenger Oil Change system. Needed to change all my fluids to finish up the 20,000 mile service so I got to try my new "toy" this morning. Here's some of my observations: 1. Removing the pipe plug next to the oil pan drain plug was no big deal thankfully. I had practically worked myself into a frenzy worrying about cracking my engine block or something equally horrible while messing with this plug. I finally told myself that if it didn't come out with just moderate force, I would put the whole kit on a shelf and not use it - no way was I getting out my breaker bar for this application! Well, it came out with the same amount of force it took to remove the other drain plugs. Reinstalling, you have to be careful because it's pretty short and I can see a distinct possibility of getting it cross threaded. I also torqued it to the low end of the recommended range to be on the safe side. 2. I know it's just me but it was a really weird feeling cranking the bike up knowing that I'd just drained the oil pan! Gotta have a lot of faith in the engineers who designed this thing! 3. Some have said they got out only 6 oz or so of dirty oil. Some have said more. The instructions say to run a quart and a half through. I decided since it was my first time doing it I'd use 2 quarts. Man, that stuff ran dirty until that last half quart went through! It'll be interesting to see how the next oil change compares. 4. Overall, it added 30 minutes and 2 quarts of oil to the procedure. I'm sure with subsequent changes the time will come down but I don't really care. To me, both of those are a small price to pay to know that my motor is now purring along with a pan full of pristine, clean oil!
