Another Oil Change

[jbfla]

Two more oil changes:

That makes a change at 200, 600, 1,400, and 2,400 miles.

I switched to synthetic oil at 1,400 miles.

This one took about 1 hour 20 minutes. About half of that was "drain time".



There was still a bit of sludge and sparkly bits:




But the filter had almost none:



I saved a sample to send in for analysis:



From here on out, I'm going with 2,000 mile oil changes, unless I get a surprise from the oil analysis report. Then I may change every 1,000.

Good to see someone else that does post-mortem filter inspections.

But,,,,,,,,,,,,, the mallet?

I'm glad the RX3 only takes 1.7 quarts of oil, that filler for the trans area really should be a larger bore. I've idly pondered laying the bike o the left side guard bars and pouring the oil in the filter & screen holes for expedience.

Please post results of the Oil analysis, I did one at 1000 miles on mine and it showed some fuel contamination. I'm really curious what yours shows. My drain bolt looked similar to yours but I didn't check the filter.

Did you have any fuel smell to the oil?

Here's my oil report.

The mallet is for banging against the side of my head....when I forget to put the drain plug back in before pouring in the new oil....

Actually it's to lightly tap the end of the socket wrench handle to loosen the drain plug and mesh filter screen covers....saves my knuckles from being scraped when the covers suddenly release. The drain plug always seems to be much tighter than when I last put it in.

I'm wondering if there should be a crush washer on the drain plug? My other bikes have one.

For putting in the new oil, I use a long neck funnel that just barely fits in the filler hole.

No fuel smell in the oil, and no measurable amount of oil usage between changes.

Thanks for posting your oil analysis report. I looked at it when you previously posted it.

I ordered the analysis kit from Blackstone as well. I imagine it will be a couple of weeks before I get a report.

Blackstone should be pretty quick, it was about a week after I sent mine that I got the results. I'm a little jealous of your southern location as I stare out into the snow here in NY!

Yes, there should be a crush washer on the oil drain plug.

Thanks Spud.

...no crush washer was present at the first oil change...


Edit: perhaps there was a crush washer...I'm used to seeing copper washers....

EDIT #2.... Senility has set in. Definitely a washer, just not what I was expecting.



That's one reason I take a lot of photos. They are much better than my memory.

You found it.

Yes, but it still doesn't look like the copper crush washers that are on my other bikes.

And I've wondered from the beginning about all the white substance that was smeared around the drain plug threads...looks like some sort of sealing compound.

Both my Honda CRF250X and Honda XR650L have aluminum crush washers. I think my oil drain plug might have had a similar substance on the threads; if it bothers you, just peal it off. The oil drain plug won't leak oil.

You're going to make me pull out that drain plug again, aren't you...

Just to see if that is a real crush washer (aluminum or not), or a solid washer.

Spud didn't make me do it, but I wanted to do another oil change before the bike goes to CA.

No crush washer this time. Don't know where it went:

Oil Change # 5





Found the aluminum crush washer stuck to the bottom of the engine.





There is still a good amount of sludge and metal filings on the magnetic drain plug.

The way the filings are standing up, I believe they are steel, not aluminum.




Only a few tiny sparkles in the oil filter:
