1986 Buick Somerset with the 2.5L "Iron Duke" 4 cylinder that had just under 300,000 when I got rid of it. I ran nothing but Valvoline All Climate 5W30 in it with a Fram or ACDelco filter.
It never burned any oil throughout the life of the car, but I had to change the valve cover gasket about every year. I guess these engines had problems with the valve cover gasket.
I later found out that the car started on fire while going down the road. The guy didn't bother with the leaking valve cover gasket and the engine caught fire.
