I wouldn't judge oil by the brand anymore. In fact, Ever since the API SM and arguably SL specs came out years ago all you have worry about is price and the fact that it comes from a well known brand.
Like others, just buy any cheap known branded API SN oil that suits your oil interval needs. Usually up to 5k for conventional, 10k for lower priced synths, 15k for top-tier synths.
You can go futher oil intervals, like conventional can do 10k, but you'll need to prove it to yourself with your specific car with oil analysis. Not all cars use oil the same and not all drivers get oil up to temp often enough.
