I recently acquired a ms3 and it only has 1200 miles on it. Any secrets you have for engine longevity? is it stock or modded? have you ever come across fuel dilution or oil shearing? thanks and congrats on a great uoa.

No real secrets- I just stay on top of scheduled maintenance. I don't baby the car but I don't constantly hammer on it either. I installed a Mazdaspeed CAI at 43,243 and a Hypertech tune at 135,545. No significant fuel dilution or oil shearing. For some reason Mobil 1 gets bad mouthed quite a bit on a few of the Mazda boards but it has certainly served me well in this-and several other-applications.
