I was surprised to see Mobil1 redcap as a 5w-50 the other day at Wallyword. Are they phasing out the 15w-50 with this new viscosity ?.
What's everyone think of the 5w-50 Viscosity. I always regarded their 15w-50 as a great racing oil , well respected by many road racers as being their most stable oil visc. This 5w-50 sounds like a really large spread of viscosity, I'm concerned they may be sacrificing something by it, unless they've improved the technology of their oils in recent times reducing the need for VII's.
