I only drive my Cayman around 6000 miles per year so based on time its near due anyway. The 987s have a possible IMS problem and a possible bore scoring problem and I feel the 10k oil change is too long for these oportunities for disaster. Just my opinion but It is what I feel is needed. Cost to do it myself is around $70.What's the experience on this - 5000 oil change instead of 10 K?
Is this a "nice to do" or actually preserves our engines … or even improves performance?
I hesitate as it would cost me circa USD 130-150 to do this half-yearly instead of once a year, hmmm!
