Call me skeptical, given the push for environment stuff. But I like the idea that they're at least aware of the need for a "supercar" oil.
Mobil 1 was great oil 25-30 years agoWhen I raced Bikes 87-95, we used Mobil 1 on all the builds and during the race season. when tearing down the motors they were noticeably cleaner and we never had any oil-related failures. We swore by the stuff.
15w50 has much more of what is missing from the regular 5w30 type M1 oil but is also not as good as something like Redline or Amsoil in my experience.We all want the “best” of everything for our toys, but I’d stick with what my builder/tuner suggests. I run mobil1 15-50 in my v fwiw
