Royal Purple or Red Line oils???

Waundering if anyone has used either of both oils.

I have used both in Motorcycles -great oils, in fact Red Line makes the best manual tranny fluid period.

That said, at my 2000 mile oil change I am going to use Mobil 1.
Part of the reason is that you can find it in so many places.

Both brands are very good.
