hi
For Mazda 3 2011 2.0 AT in the vehicle manual, the engine oil required for the Mazda is 5-30w sm or 10-40 w sn.
The air temperature in our city is 20 ° C min in winter and 46 ° C max in summer.(iran)
Is the use of engine oil with a viscosity of 5-50w sn suitable for this temperature.
If not, what the viscosity of the oil should be??
The machine was running 7000 kilometers and the previous oil had a viscosity of 10-40 w sn .
Now I want to replace the oil or use the oil with a viscosity of 5-50w sn .
I replaced the engine oil and the oil with a viscosity of 5-50 sn and With this
engine oil gone500 km I have to change the oil again or not???
Does this type of oil harm the engine?5w-50 sn
PLEASE HELLP ME
THANKS
