Like I said as long as it is a LL-1 oil just go ahead and try any of them, there is no absolute better in this, at least not for every type of climate.

Thnks! here in spain we have castrol 5-30 and 0-40 but now some dealers are using SHELL which I donīt like... Mobil 1 or Castrol are my preferred brands
