I have a 1999 Chevy Silverado 4×2 extended cab 5.3 liter with about 192,000 miles on it. I have always babied it in regards to changing the fluids, filter, etc. and using the best fluids possible. Obviously it has very high miles but even after oil changes the "Change Engine Oil" message still appears. I have tried resetting the message (pump the brake 5 times with the key in the on position). The message flashes when I do this but it still appears after start up. I have read in the owner’s manual that this message is based off of oil burning (?) and not mileage. I don’t know what this means. How do I fix this problem? Does it mean that oil is passing the rings and burning in the cylinders?
