Oil Selection?

Greetings, I will have my car maintained, but I am undecided about the oil, I had Castrol Magnatec 10/40 in the last maintenance, but what is the difference between 5/40 and 10/40 that stuck in my head as if the engine sound increased? Which brand should I choose?

I do not know the difference clearly, so I will go to this topic and write better friends, but generally they use 10W40 in 206s. Most people are in many places. I don't think the engine sound will increase accordingly.

Sir, these numbers simply show the operating temperature range of the oil, you can use 5/40 or 10/40 under Istanbul conditions, my advice is castrol edge 5/40

I think there is no need to say 5/40 a total of 10 40 oil is appropriate.

It is good oil in total, gasoline diesel can be used in diesel without particle filter.

I was using 10w 40, at the last oil change the master said let's put 5w 30 better. I am using Shell Helix 5w 30 right now. There is no problem
