Trackday advice

[topboss]

I have been invited along to a trackday round Donington in my Tamora. The car will have covered about 4,000 miles by then but is still on the "intermediate oil". Will the car be alright to be tracked on this or should I get the 6,000 mile service done early?

Any thoughts much appreciated.

Dealer said the car is using semi-synthetic at the mo with the upgrade to fully syn' to be done at the next service. Would you recommend changing to fully syn' before hand?
