2017 Corolla oil change
I have an Corolla from 2017, 1.6, valemantic, 132hp, 45.300 km on ODO. I bought this car second hand, from Germany.
Recently I've made oil change - 5w-30 they put me. They said that this is the correct oil viscosity for car age and km on ODO
I've seen that the owner manual preferred is 0w-20. I can used 5w-30, but after that to switch back to 0w-20.
I'm living in Romania. Temepratures during the winter can go to -10 Celsius, to +35 Celsius in the summer
Theoretically, they put correct oil for these conditions, but owner manual is recommending something else.
Questions and concerns:
They put the correct oil after all giving weather conditions?
If I have right now 5w-30 it will affect my car?
Should I switch back to the 0w-20 at the next oil change?
I wouy used to zero 20 in the winter and the other one in the summer
Thank you for fast answer Scotty.
