I'm now going turbo with my S. What oil and viscosity should I use? I have been using Castrol Magnatec 5w-40 until now, and like it. Would it be ok to continue to use the same oil now that I'm going turbo? Or should I use another brand or another viscosity?
Keep in mind that I live in Norway, and we don't have Royal Purple etc here. Some well known brands that are quite easy to get here would be f.ex Castrol, Agip, Mobil 1 to mention some. My experience with these so far is that the S uses noticeable amount of oil with Mobil 1, and uses no(!) oil with the Castrol..
Greatful for any help!

 

Your staying with the stock engine so what honda says its ownly the turbo feed that is different .I here that 5/30 can fin out by the time it gets to the turbo .

 

I run amsoil 10w40.

 

Brad Penn 10-40 6 quarts

 

same here. amsoil 10w40. just started on it...

 

Mobil 1 Turbo Diesel

 

shell rotella T6 5w40.. nearly as good as the premium oils but much cheaper

 

Amsoil 10w40 here also

 

I run shell rotella 15w40. Oil Consumption decreased significantly from when I was bone stock running synthetic mobil 1 to now turbo and running shell. I would stay away from Castrol. I work for a company that develops oil additives and in our severe duty testing Castrol has always performed badly.

 

Hmmm. How about Gulf? F.ex Formula G 5w-40 or possibly Racing 5w-50?
