IMO, the only reason that you wouldn't get approvals is if you are in the business of basestock shopping, and don't want to have to recertify every time there's a change.
Wait a minute. Don't they limit zddp?
Phosphorous ???
min 600, max 800 for oils that are to be certified against GF-5, so really only 30s, 20s and below...Redline wouldn't be certifying against GF-5 with a 5W30 with an HTHS of 3.7 anyway, as it's clearly not an EC oil,and couldn't meet the economy requirements.
Other than the ILSAC grades, they can play to their heart's content.
There's also no limit for Undetectium, either in the current specs, or on the horizon I believe.
