Oil Change?

Just searched for post about oil change, but couldent find what I was looking for…

So how often do you guys change oil/filter… Every 2 track day??

I have already topped it up with 2.5 liter …so I guess its time to change it again???..

Every 2 track days is my rule - or if it was hot day and I did lots of miles I change anyhow

On the VHPD I used to change it every 3K miles. They overfuel very badly which causes oil contamination that you can see by looking at the oil (it goes black). Its very important to keep an eye on the oil and its colour and change it accordingly.
