What is your typical engine oil change interval in the beast?

Owner's manual states every 10k miles... I maybe "old school" in thinking that's too long. Just wondering what other owner's are doing---especially those with 150k+ miles on the clock!

[MaxRS6]

Every other track event- or 4500 miles- whichever comes first

[Elevens]

Every 7500mi using Pentosin 50W 40 Synthetic........

Once a year -- I never put more than 6K miles on a car in a year.

10.000 km, whatever that might be in miles. ;)

Twice a year, 6 months apart, approximately.

Works out to between 3000 and 4000 miles most years. I have 50k in the 9 years so far.

every 9-10k km which is about 5-6k miles.
