I've owned and personally serviced five Hyundais over the past 17 years. Not one of them consumed oil in excess of a 1/4 quart over three-thousand mile OCIs. All except my current '03 Sonata V6 clocked well in excess of 175,000 miles on conventional 10W-30 motor oil - generally in the lowest-common-denominator price range. None were babied or beaten. My late ex-wife's '02 Taurus with the DuraTec V6 was an entirely different matter. It started out consuming 1 quart per 3,000 thousand miles and by the time the warranty was up, had graduated to 1 1/2 quarts per 3,000 miles due to leakage. Ford insisted that, and the leakage, was normal consumption. Fortunately for me, by the time she bought that car, neither she, nor the car, were any longer my concern. You Hyundai naysayers can say what you want about the brand, but the company definitely knows how to, and does, build reliable engines. Transmissions are another matter.
