It not a case of the manufacture building dodgy engines, it's a case of how they are serviced and maintained over the years, wrong oil used will not allow the engine to bed in and this is a major cause of oil usage, infrequent oil changes allow carbon and sludge to build up in the ring lands and this is also a big concern, over heated engines will damage the tension of the piston rings, so many things can cause problems the damage may have been done long before you purchased the car, so allow your mechanic to determine the best action to take to rectify your problems.
