Vannies!!! Next Oil Change

[MADVAN]

Warning Vannies Be shure from now on you use oil rated CI-4 or higher.
With the use now of 15ppm diesel fuel we do not need the old oil package to combat sulfuric acids. With the loss of sulfer in the fuel the package will cause carbon buildup behined the rings causing Premature failure/wear. This is also wears the cyl bore.

Where do Shell Rotella 15W40 and Valvoline 15W40 fall in relation to this spec?

What about Valvoline full synthetic 5W40?

I've started using that in my 7.3 truck, and ran it once in the 6.0 van.

Manufacturers have changed/or changing to the new api. Have to be on the lookout for old stock and what i consider off road use. The oil's are ok if running 500ppm fuel (off road)
Us 7.3 owners do not need the CJ-4.

I posted this due to Iam one of those long long distance oil changers.

If I understand this right -- should this instead state "should not use" ?

You can use. Just not required.

CJ-4 is superior in most ways than previous oils, and it won't be long before it will be all that is manufactured. It is especially engineered for the new emissions equipment and doesn't really have much relationship to LSD or ULSD. Use it and don't worry about it.
