Absolutely not! It is a fact that cleaner oil promotes longevity. The big question is when does the oil loaded up with contaminates to the point it becomes detrimental to the moving parts? Mobil 1 is synthetic oil so don't have to worry about it breaking down with age and becoming acidic like stand oil. The new cars are built to a lot tighter tolerance then older cars so seal blow by is not as great, but there is still heat and there is still friction that generates wear and particulate. So 3K miles may be way over kill but if you are doing your own oil changes it is cheap insurance like using tier 1 gas to reduce deposits. I personally change my oil every 4k - 5K miles, it only takes about 15 minutes using a Top Sider oil evacuation pump ($50 from Overton's boating supply).
