I read that the recommended viscosity is 5W30 which is good up until 38 degrees celcius, over here in the summer it can get up to 50 degrees celcius so what do u recommend I do? is it bad to put a different viscosity such as 10W60... Moreover is it normal that i feel some heat from the dashboard when the A.C is off?? over here they usually use 10W60 for oil so what do u guys think?
