Track vids, oil separators, oil analysis....is there anything you don't study for the greater good? Another must-subscribe thread from dmichaels. 
I'm just coming up on 3000 kms (1800 miles) on the original oil and am debating when to change, but wanting to do it sometime very soon. I haven't been a fan of M1 for a few years now...mostly because my turbo Subaru's drank the stuff, but didn't burn a drop on other brands.

I spoke with tech support at RP and asked about using 5w-50 (RP has a 5w-40), unless you have sustained 5-7k rpm for 20+ minutes there is no need for higher weights. The higher weight oil helps remove heat from the engine and helps maintain a minimum hot oil weight during sustained heating of the oil. In almost all cases on the street there isn't enough room to heat the 5w-50 oil for its intended purpose.

I plan on doing an oil sample at every change. I'm using a 6k interval, 3k tire. rotation. If its coming apart I'd like to catch it before its catastrophic.
I spoke with tech support at RP and asked about using 5w-50 (RP has a 5w-40), unless you have sustained 5-7k rpm for 20+ minutes there is no need for higher weights. The higher weight oil helps remove heat from the engine and helps maintain a minimum hot oil weight during sustained heating of the oil.

Also completely agree for the street driving, there really is no need for a 50 weight oil

This topic is pretty subjective as everyone is able to drive their car in different manners. I'm fortunate to drive my Track Pack in a manner in which it was built for. I don't use the MC oil in 50 because I didn't like the way my car ran, the oil consumption I experienced, the availability of the oil here in Germany, and the cost.
I switched to RP 5W-40 HPS and couldn't be happier. Everything listed above has been voided by the switch. But it's my car, my driving style, and my money.
