hello guys...

tanong ko lang possible causes kapag nababawasan ng langis yung makina. haven't had an oil change. however, in that period, have already added a little more than a liter of oil into the engine on two occassions already (so a total of more than 2 liters of oil was already added).

haven't checked the sparkplugs, though. but it seems the exhaust is quite okay. not smokey white or grayish, not even a trace of black smoke. also, i haven't checked the sides of the oil pan for leaks, but if there are any, it would show several drips in the garage, right? there aren't any, i think.

have had brought the car to a trusted mechanic, but forgot to mention about the oil. the mechanic just added the needed amount and said nothing about it.

so, could you give any insights on that... thanks.
