yeah, I had a 2005 Mazda 3 with 75,000 miles and sold it after getting the engine rebuilt after I spun a bearing.

I had switched to 5w20 synthetic on the prior oil change. I drove the car pretty hard. I was low on oil when I spun the bearing. Probably at least a quart low after 2500 miles and I had not checked. My fault. However, while researching the issue and hearing from other members here, it appears these engines are sensitive to oil level. i have also read about others changing grades of oil and not using synthetic.

What does this mean to you? Dunno..but I would consider a different weight and check the oil frequently. Being in a cold climate, I am not sure what your options are. Be diligent.

I purchased a new Mazdaspeed3 and love it.
