I have never been able to make my car Vitz 2012 oil level to Max level just because of fear not fill more then Max except the day Lube guy pour fresh oil (3 litre liqui moly 10w-40 and 150ml liqui moly oil additive) and that was my 2nd oil change from the day I bought this car prior to this oil change! In first I poured 0w-20 Toyota Made in Japan engine oil just to think that it will be best for him without having enough knowledge that if car got thick engine oil habit it’s not good to go down which cause very very bad result that after driving 3800km I bring car to a lube shop to have routine check up I come up only 700 to 800 ml oil left in my car. There I like to mention few things that when car got 0w-20 I feel vibration in engine so I thought it gonna fix after sometime due to change of oil brand, 2 time car get off while driving but get start on first time but feel less power, on hard paddle I feel slow response to run it fast but I had no idea where is the problem even due to this experience I also replace my plug with original plug also
Let me conclude my post that after having very less oil left condition we immediately decided to first flush engine, poured 10w-40 liquimoly oil as already mention along with oil additive and have been advise to check oil level after every week since from that day I check my oil level once after every week and drive about bit more then 2000km in between I poured 2 time about 100 to 150ml oil just not to fill more then max level here is the current oil level from both side of oil dip stick. Last, day before yesterday I also done compression test of my car and results are A175, B150, C150.
