When I was changing the oil recently, i found that it has decreased the level till the lower point. About 7-8 months ago, I have changed the Rings (only) as at that time it was decreasing oil continuously but when we opened the engine everything else was in good condition so we changed only rings and the problem solved. The engine was never overheated after that but this time i done 3500km on that oil while i usually change it at 3K.
Now there is no smoke at all from silencer, neither from the oil place (when cap is removed). Only sometime it does little missing but not so often, although i have done computerized tuning recently.
What else should I check to confirm whether the engine is ok or there could be some problem. Or should I wait for the oil this time. (till now it has done 200 km and almost no oil decrease). I always use GTX-castrol 20w-50 (dubai version not pakistani).
