Why ask after you have it changed?

 

Better late than never i surpose

 

Millers CFS10W60 is generally recognised as an excellent choice.

Have a look at the flyer for their motorsport products and decide for yourself.

The suggestion that thinner oil is needed for cold conditions is partly correct. BUT if you allow you engine (coolant and oil) to reach operating temperature before giving it grief, this becomes much less relevant.
