bit worse than i thought, although not bad enough to stop me going to donny LOL 
drained oil filled my measuring jug up to the 650ml mark, so im guessing ive lost around 50ml over 7 sessions on the track and around 100 miles road use! . sound okay to you guys or is it something i should definatly change before the next track day in 2 weeks, ???? i was gona fill it back up to 700ml's and take some with me to the track, and just keep an eye on it!!!!!! What do you think!!!!
