What would you do if the car was sitting not run for 2 months? ( I'd turn the key, let the motor run for 60 sec then drive. )

The real worry here is that the oil you poured in the cylinders has gotten between the top and 2nd piston ring. If the motor is run hard before the oil has a chance to escape, the expanding oil will break ring lands. Not to mention if you don't get nearly all of the exposed oil out, compression ratios go sky high.

A similar problem happens on gas race motors that have been flooded with fuel.

If you want to do something to limit dry starts, pull the glow plugs crank the engine until you get oil pressure.
