I don't think anyone here is denying the fact that there have been engine failures. But those are rare and don't have to do with the engine, but some 'other cause' that makes the engine oil to disappear. To be honest, this is the thing that worries me, but just need to be diligent!

I think as long as you can make sure the engine oil is there, you wouldn't have any issues. I haven't had any issues, actually i drove 1300 miles this week, and not a single drop of oil was lost. I use Mobil 1 synthetic, do the maintenance on time, change the PCV every 10K, and ocassionally use seafoam for 100 miles before the oil change to keep it clean. Haven't had any issues
