Im from the UK and got this reply from Tim at opieoils yeterday I am using the Motul 15w-50 which is fine but have been advised that 10w-50 gives better cold start protection
Here are some very good, well proven choices.
Engine 5L (Go for a 5w-40, unless heavily modded or a lot of track use, then go for a 10w-50)
