Hello dears,
I have Mira 2012 (79000 km driven) which even gave me 32 km/liter and normally 18/19 km/Liter. What is the best grade engine oil in castrol to use, please. Someone recommended 10W-40. I feel like Mira is a small car and there should be light engine oil to use for these small engine.
Note: I bought the car some 08/09 months ago. I do not know which engine oil is previously used.
Expert/experienced opinions are highly appreciated, please.
