I did a search and it's a question that has probably been asked many times before, but what should we be running our cars with? Manual states Mobil 5w 30 iirc?
Cheers

Loads of discussion on that here! I'm just about to switch to Castrol Magnatec 5w20, the grade which Ford advises you to switch to instead of 5w30. Done over 200k miles on Mobil 5w30 though, so clearly OK!
