Actually SHR does use Mobil 1. QS is used by Hendrick which builds engines for SHR, but SHR can use any lubricant they desire. HMS has no control over the engine after the lease to SHR
The Duece has been impressive so far also. If Brad can keep it together he maybe a strong darkhorse. My only feeling is nacar wont let that happen this year. Nascar realizes it's Tony or Gordons turn again
