To be on safer side, i decided to put Engine Flush on next Oil Change.
Air Filter was brand new so i didn’t replace it.
I used Total Quartz 9000 5W30 with Leppon Oil Filter.
Oil change interval is 5000Kms.
On next oil change if the car didn’t reduce oil, i will use Engine Flush and keep using Total Quartz 5W30.
If the car reduced engine oil by half, i’ll put Kixx Pao 5W40.
Thanks for the Suggestions everyone!
