The Tribol Leaders have spoken on this matter.
Head to the mainland for new oil and coffee.

He only has 500 miles on the oil but he rides hard. I think what he’s asking is there any benefit to draining and straining the oil through a coffee filter every few hundred miles in between the regularly scheduled oil changes.

I don’t see any harm to it. You could try it once and see what the coffee filter picks up. If there’s anything visible in it then yes, it might be worthwhile.

I agree with the above post, the oil isn’t outside the specified change interval, just an in between and reuse. Actually would be curious what shows up when he does that.

I suppose you could use some kind of toilet paper filter arrangement like many in-vehicle bypass filters use if you are willing to wait for the oil to soak through...many users of bypass filters will run their oil for tens of thousands of miles.
I imagine a significant portion of the oil from a small sump would end up staying in the TP, though....might not be worth it.

I doubt a coffee filter will do jack...

The issue with fine filtration is that oil shear, additive depletion and liquid blowby contaminates are not addressed.

Over enough time, you could end up with an oil that is diluted by as much as 25% gasoline by products, a few grades below spec and acidic.

The oil change is the only way to ensure clean, serviceable oil.


HOWEVER, ongoing submicronic filtration has some significant advantages, as the oil never accumulates larger particulates. Such particulates are known to contribute to timing chain and piston ring wear.

...

This is how I read it also. Not re-using 2000 mile oil, but draining and coffee filtering the oil every 500 miles then putting it back in.

From what I can find, coffee filters are ~20 microns, so a decent particle size will be caught. Is it worth the hassle of doing it and would there be any benefit?
Don't know anything about this engine, but from a quick google search, this thing has both oil filters and oil screens, so the engine is already filtering the oil.
Why go through the hassle of draining, filtering and pouring back in (as well as having to use some new oil for top off)?

The challenge is how to keep the oil from contaminant during the process of draining, filtering and putting it back into the engine.

A clean to the eyes container can or coffee filter, may have bigger contaminant than that of the one there.

I don’t see any harm to it. You could try it once and see what the coffee filter picks up. If there’s anything visible in it then yes, it might be worthwhile.



I'd like to see those used coffee filter pictures posted here. Who knows what you are going to find unless you try it.

I have done this before.
I changed the oil in my Scion @ 5000 miles for warranty. I was using synthetic and I am sure there was nothing wrong with the oil, so when I drained it, I drained it into a clean 5 qt jug. Used the oil for top off oil in my truck and brother in laws truck. Before using it, I filtered it through a coffee filter (poured it from the 5 qt jug into a 1 qt bottle, used the filter to make sure it was clean).
The coffee filter had nothing in it that I could see.

If this was a moped or other bike with no filter, I would imagine there would be some stuff in it.

Not motorcycle but I've tried filtering engine oil through coffee filter (10w30), it won't go through fast enough if you value your day for more than $1/hr topping it off. If you want to, use a larger pores filter (i.e. cloth, paper towel) and then let your oil filter do the job cleaning out the small stuff. If you are concerned just use cheap new oil.

My question is can I dump the oil, drop the screens and filters then run the oil through a coffee filter and re install every few rides? Last oil change was @ 2000 miles.

I can't believe I am reading something so ridiculous like this.
