Purchased my used 2009 Mini Cooper S with the JCW stage 1 installed. Had 81,000 miles when purchased 6 months ago. Now it has 87,000. Only problems I've had with it til now, I had to replace the turbo oil feed lines with new SS Detroit tuned lines. Old stock was leaking oil... I'm not sure but I think the valve cover is leaking oil? When I come to a stop I will notice it wants to stutter or rev inconsistent? Not sure how to describe it? I only use premium gas from chevron. I use castrol full synthetic 5-30w. This Mini is a blast to drive and impressively fast! Found lots of good info on here. Hope to meet with some knowledgeable local mini owners to pick up some good info? Hi everyone!

 

Hello and welcome from Tucson. I'm sure you're doing a lot of smiling with those miles. Good job.
