Can anyone advise which engine oil shall be used for 3A90 Mitsubishi Mirage 2014.

I tried OW-40(Make: Mobil1) and 5W-30 (Make Micking)

With OW-40(Make: Mobil1) car pick was slow. With 5W-30 (Make Micking) car acceleration has improved but engine start time from cold state has increased.

Any recommendation please.
