Looked at the FAQ section and the comprehensive posting on engine oil that 5w-30 Oil is specified. I also note from my handbook and logo under the bonnet that MINI recommend Castrol. However when I went to my local spares shop who stock Castrol Oils and they didn't stock any 5-30 not castrol or any other make. The guy behind the spares counter said that Castrol Formula SLX 5w-30 is the correct oil for the new MINI. The Bottle states that it's suitable for modern BMWs and Audis so I guess this may cover the MINI as it's a baby Bee Em!

I bought a litre bottle but haven't opened it yet so if it's the wrong stuff I could take it back, I only need the oil for topping up purposes in case the Engine uses any, I've done just under 500 miles of running in so far and it hasn't drunk any yet.

I note that the FAQ post originated from a US MINI2er so maybe its just that 0w-30 is the grade of Castrol available in the UK and the 5w-30 is the US equivalent. After all 0w-30 has a wider viscosity range than 5w-30 so I guess it may be considered a superior grade in any case?

Can anyone give me a definitive answer on whether Castrol Formula SLX 0w-30 is indeed the right oil ffor my UK spec MINI Cooper please.

Thanks
