Never any black smoke from the tailpipe, no leakage from crankcase (was checked), compression test revealed the compression was close to that of a new car. Oil seems to be going down 1/2-1 qt. every 1500 miles.
IS THIS TOO MUCH OIL USAGE? The whole engine would have to be taken apart to see leakage in valves. Does the compression test prove anything?
Compression was one point off that of a new Sonata.
ANY IDEAS OR SHOULD I JUST KEEP ADDING HIGH MILEAGE OIL WHEN IT'S DOWN? Tried that Lucas oil treatment but hard to get into crankcase as it is
almost solid petroleum. Adding oil for engines over 75,000.
