The oil monitor is not a timer to tell you when it is time for an oil change. It works with how the engine is used. If you only do city driving and small runs the life of the oil will be shorter. For people always on highways mostly you monitor will makes your oil last longer. Do the test in winter and you will see a large difference with summer months. For your oil going full synthetic is the way to go but an oil change cost more. You recover your money by a longer life. The only drawback your monitor does not know the difference between regular, semi synthetic, and full synthetic so you get the same life on all oils. For me no matter the mileage when my monitor show 50% I change it. For the small mileage I run it does not makes much difference. Same if the gas would cost $4. per gallon it would not burn my wallet either. Lol.
