"The notion of piston ring gaps lining up to drop compression or increase oil consumption is an old one, but has no basis in fact."


I disagree with this one. Worn or aligned rings will give an increase in crankcase pressure and this can shove oil out the breather and down the inlet valve guides if they are worn too.
