it dosent matter if its full or empty, oil wears out period. 255-239=16. you have driven 16 THOUSAND miles without an oil change 16/3=5.3 you are 5 changes overdue. the oil in your engine is no longer providing the protection required by it. and if you continue to run the car on this oil the bearings will go bad. i can only imagine the sludge buildup in your engine after running your car this long on that oil. and heres a fyi. the previous owner of my now wrecked bonneville ran the car about 15k on an oil change before i bought it. 2 weeks after i bought it the engine threw a rod and blew. sttarted knocking less than 1mi from my house, got it in my driveway and boom. done.
$20 for an oil change is a WHOLE lot less than replacing an engine.
