So i've bought a 10 year old City with 60k on the dash.
It's running on 20w50 oil and some people have told me that it's too thick and to get it replaced with 10w30 or 40 max.
The oil is basically new like couple hundreds driven and considering the sadma i'm thinking of keeping it as is and change the oil on next cycle which'll be after 5k.
Can it affect the engine or is it safe to keep the car on current viscosity? Thanks.
