- How Many Drag Passes On Your Oil? -
I was just wondering how many 1/4 mile passes you guys put on your oil? I typically do just one track day, which is 25-35 passes and a total of about 75-100 miles. I usually change the filter every 2nd or 3rd oil change.
Perhaps I am changing the oil excessively, but I worry about the clutch particulate. Is the particulate small enough to get filtered out? When I burnt up my clutch the whole oil pan was coated in clutch fiber material.
I have used this change interval with synthetic and dino oil. My thoughts are that the synthetic will offer no additional protection against the clutch fiber material.
Thoughts?
Shane

The truth is Shane, you might be better reasoning to do the opposite of what you are doing now. The oil filter could be changed two to one over the oil imo. I guess it depends on the oil everyone uses too. You have to figure every single drop of oil will flow through that filter and every particulate in that drop will be captured by the filter slowing oil flow over time.
With that said, it looks like I have been changing oil and filter at about 75 passes, sometimes less than 50. I cut the filter open and strain the oil to inspect. Not much fiber material at all since the lockup was installed.

I do between 60-100 passes. I wander the same thing as well. I ordered amsoil yesterday and talked to their tech for a while about this. He said the thing that hurts the oil the worst is when fuel bypasses the piston rings and contanimates the oil. That's what causes it to break down. He said the clutch fibers wasn't as nearly as big of a concern as the fuel in the oil. He said with us going WOT from a stand still that's what's hurting us.
If any of that made no sense to you, just disregard. I confused myself trying to remember what the guy said.

I guess I'm just not sure that the oil filter is getting the small particles. But I suppose that if a clutch lasts me 150-200 passes, that means that I am putting 25% of my wearable clutch fiber into the oil every 50 passes.
That could be unacceptable filter loading, and doesn't sound too good for the oil either.
Thinking of it in those terms, I don't see a compelling reason to reduce my oil change intervals, but perhaps I should be changing the filter each time as well.
Thanks for the food for thought...

Good point of the fuel contamination; I didn't know that would be a big issue. But I do see the fuel in there sometimes, especially since my map is a little on the rich side.

The oil filter is filtering in microns. The filter micron specification I dont know, but filters for other engines I have seen have been 5-20.

I used to go 75, now I go 100. This is with Amsoil and an OEM filter. Then I take the used oil, re-bottle it, and use it in my lawnmowers.

75-100 passes seems like a lot on one change...that's around 1/2 of a clutch for me.

i change it after two trips to the track, could be 5 passes, could be 25 passes. and there is usually some hard street miles in there. i like to look at the oil and clutch.. gallon of oil and a filter is around 20 bux... thats pennys on what i've spent so far.

But the amsoil guy said the clutch fibers isn't as big of a deal as the oil getting contanimated by fuel...
And to you guys that think rotella synthetic is junk, the amsoil tech said it was a very good oil and he personally knew a bunch of guys that run it. It was rated ma while the amsoil is ma-2

Blowby of hydrocarbons is more of a problem on nitrous bikes but, just the same, happens to all of them.
Rotella T has become a very highly rated oil by motorcyclists of all types in the last few years.

Fuel certainly breaks down oil. I do an oil change roughly every 50 passes. My oil is usually very clean and has minimal metal or clutch particulate in it.

yeah Shane do the opposite, the filter is where the bad juju is. last season, break in oil new filter. a few test runs on the road. new filter and top up on the regular dino oil. first race wknd on dino. change oil and filter to Royal Purple. run maybe 5 wknds then change oil and filter. oil went in the truck 50 50 with its regular stuff.
now with the ti winder you should drop the pan every now and then just for piece of mind. see how much crap sits on the bottom, if any.

8 hours of track time, with only about 15-20 bikes to the whole track.
What bothers you about 6 quarts of oil?

The sump level is the same as stock, and the pan is covered/baffled for windage.
