My recent oil change experience

Before anyone says "here we go again another oil thread" I wanted to post my recent experience.

I ride a track only 2006 KTM950SM which has a dry sump lubrication system.
Basically it has a separate oil reservoir instead of having an oil pan to store the oil. There are other advantages about utilizing a dry sump system for performance engines but I only mentioned it because this engine has a screen tube to filter the oil before re-entering the tank and a long paper style filter common to dirt bike engines that is used before that oil is sent to the engine for lubrication. I use the KTM preferred Motorex 10W-50 Syn T which runs around $15.00 per quart. The oil capacity is 3.5 quarts and the screen gets cleaned and the filter replaced at $19.00.
Thats $80.00 per change!!!

I just changed the oil at the start of the track day season and the bike has 600 track miles for this year. I figured I would do a complete oil change which requires draining the slight amount of oil at the bottom of the engine, the reservoir, and cleaning the screen and replacing the filter.
The drain plug after removal had the usual pieces of clutch material and slight metal particles on the magnetic part of the plug which is totally normal. The bike has an STM slipper clutch which in my opinion wears the plates a little more than without it.
Anyway I cleaned my oil drain pan really well before I started my project to make sure I could get a good view of how "dirty" the oil looked after 600 hard miles of track use.
I brought home a white paper funnel/filter from the shop that we use to strain paint before putting it into the paint gun cups. Nice and white and clean for my inspection of the oil that I was changing. I poured the oil through the funnel and into a clean clear plastic cup for inspection. There were no particles of dirt or metal in the sample I tested and the the oil that I took out of my engine looked amazingly clean.
I really thought long and hard about re-using it!!!!

In my years of racing 4 cylinder bikes I never really looked at the old oil.
I just dumped the old and added new and screwed on a new filter.

This is not an ad for Motorex oil just a thread about how long oil can last in track conditions and I can assure you I am going to wait till 1500-2000 miles before I change it again!!!!
I do think the dry sump system which has 2 filtering methods may attribute to cleaner oil than a engine without it but I am sold on the fact that these modern synthetic oils can be used much longer than most people keep them in their engines.

my concern would be judging how "worn" or not the oil is by looking at it
600 track miles sounds like a good return to me, not sure if I would spin the dice on 1500.
just my .02 cents

Stay tuned.........

Thats one of the selling points of modern synthetics, probably wouldnt hurt to go to about 1000 miles, but to each their own.
