Following.. I always use 0w 30.. Would 5w 40 not be too thick and over heat ?

Totally incorrect. At high heat you want something thicker. Track/ drift car runs 10w60 because it hangs off 7k all day long. People do bottom ends on 10w40, I've yet to on the 60. Just make sure you have adequate drain back to the sump so you don't full the head with oil. *cough* RB26 *cough*

On track these engines run pretty cool. Electronically controlled stat and waterpump drop the engine temp right down when you floor it, it intentionally sheds something like 17 C.

Runs hot for efficiency when pootling about though.

Peter I'd just get it from Opie Oils.
Always good prices and if you tell them you're a member of this forum (others included too) they'll give you a little discount.

Plus you can enter your reg online etc using their site which will show you all available products they have for your car. :wink:
Trader on here too btw: viewforum.php?f=81

Neither of those mention the LL04 BMW spec but Opie list the 5w40 Titanium FST as being LL04 so of the two that's the one you probably want, not the 5w30. If you're planning on giving this to a dealer to save money on a service then you'll need to ensure it is LL04 otherwise they're very unlikely to agree to use it
https://www.opieoils.co.uk/p-60457-cast ... e-oil.aspx
https://www.opieoils.co.uk/p-713-castro ... e-oil.aspx

That deal is cheaper than Opie even with the BabyBMW discount code (BBMW gives 10% off) so worth considering, but if you're not set on getting Castrol you can probably get other good brands just as cheap if not cheaper from Opie

The Castrol website lists Edge Titanium FST 0W-30 for my 2015 LCI.
