Mein Auto: 1997 318is
Question Substitute engine oil

Hi there
I have a 1997 e-36 318is/M44 engine (Euro version) BMW, with @16,000 Miles in wish I installed a Downing Atlanta Supercharger.
The car has been serviced by a BMW concessionary since new and they have been using BMW Super Power oil SAE 5W-40, which I understand is synthetic oil, as well as, Castrol is the official BMW oil fabricant supplier (Please correct me if Iím wrong)
My question is: Which Castrol brand oils should be the perfect substitute for the BMW Super Power Oil SAE 5W-40?
Other then the recommended Castrol perfect substitute, please feel free to recommend in addition the top notch Castrol oil you think would be the best one for this car Supercharged M44 engine, which I use on the streets regular drive occasionally, as well as, on Track days too.
Advanced thx for the broad help
