I spoke with George, the ExxonMobil site supporter. Very nice guy. Here is what he has to say about the oil.
Mike, again thank you for the call on the Mobil 1 R. We put in requests with Mobil regarding availability and should have something by Monday. And certainly will post on Bob's site. I immediately went to the site looking for the discussion but could not find it but will obviously look again, thank you. Obviously I am most interested in having this oil available as we hve supplied the oil to Penske racing for the past year in 5 gallon pails. It *is* an incredible, state of the art oil... It is what Rusty Wallace and all have been running; except Ryan who is running a 1A version of the oil... George Morrison
