Yes, i know, not another damn oil thread...

My question is, for those of you who strictly run your bike on the track (no road miles). How long before you change oil?

I run motorex and I do 3 trackdays before the oil turns near black in color when i look thru the window. Comes out to roughly 400 miles.

What about you?

1 Hard track day and that oil is outa there. Motul 300V of course!!
Same on the dirt bikes, one day on the track, and the oil is drained. I do filter every second change.

Just cause the oil is darker does not always mean it needs changed... and doing one track day and dumping the oil out is crazy IMHO if your doing that hell I would gladly take your used oil off your hands and use it in my bike.. thats just wasting money in my eyes... but if you have the money to burn then by all means go for it LOL... I always atleast went 3 -4 track days and or races before changing my oil.. but that was back in the day and I ran Motorex oil also and never had any problems..

oil changes color because it is constantly burning while cycling through a hot engine and carbon deposit from spark plugs. changing after 1 track day is way too soon. The oil will not loose viscosity or its ability to lubricate or cool the motor as early as 1 track day. id say 3 track days is an ok time to change but the oil still has a lot of kick in it.

The reason I change it after beating the crap out of it, is because even though the oil is still good and looks good, I can see clutch particles in it when I drain it... some fine stuff that the filter does not hold. So I dont like that floating though my engine.

As for the dirt bikes, the Kawasaki owners manual even recomends changing it after a race or full ride day. I also see clutch particles in that oil when I change it too.

I change mine about every other track weekend. I also have the predrilled magnetic drain plug to collect all the metal from the oil which seems to work good. I like Motul or Castrol R4 Superbike.

I would still take that oil from ya LOL and just filter it through two coffee filters and run it in my bike with no problems im sure....

where do you guys buy this magnetic oil drain plug? and do you actually find particulates stuck to it when you pull the drain plug out? Sounds like an awesome idea

You can get the magnetic drain plugs off eGay i'm sure.

I use Motul 300V and i change the oil every other track day (a race weekend counts as 1 track day) and i change the filter every other oil change.

I change mine between each session. :eyecrazy:


I love how some guys think they're impressing people by telling how they change their oil all the time. Like the fact that they barely use their oil makes them faster riders or some kind of wonder mechanic.

:rolleyes:


Change mine after a weekend at the track. Like others have mentioned, it's not really necessary even after 200-300 miles at or near redline but that's an easy way to do it since the bike's already "apart" for cleaning, lubing, etc. after the weekend.

Good filters trap particulates measured in microns. I'd venture to say you aren't seeing that much of your clutch floating in the pan or you'd have to change the plates by now.

Any serious trackday rider that isn't getting a UOA done is a fool.

I've got 6 track days on my current oil. Dumping it now for the Arkansas trip this weekend. I run Rotella T or Delo 15w40 non syn.

If it trapped particles in microns it would be plugged up very quickly to the point where no oil could flow through it. The clutch is not much different than your brake pads. You can wash your rims until they are shiny but after a ride day they are covered in brake dust, yet the brake pads last THOUSANDS of miles. The clutch does the same thing, but the "dust" is in the oil.

I do 3 race weekends on my bike. 6 days is still too soon, but then you know it is done in time. BTW I run Maxima full syn and have in all of my race bikes since 2004.
