Got a 52,500 mile service coming up soon. I've read some of the oil threads on here and was thinking of going for Motul 300V Competition (15W/50) or Castrol RS (10W/60). Where do you get these from? I tried Halfords last weekend and they only had the 0W/40 Castrol RS and the 0W/40 Mobil 1. Well, they did have some Mobil 1 Motorsport 15W/50 but only 1 litre cans

 

I ordered mine from demon tweeks.

 

Yep, demon teaks for me too - 01978 664466
Buy 20 litres and get a discount.
