Detroit has already approved FA-4 back to EPA10 engines (DD13/DD15/DD16).
Post confirmation article or news that Detroit has approved FA-4 for EPA 2010 DD engines. I have not seen that anywhere. As was stated by others, I have only seen that FA-4 is approved for 2017 engines. Engines require different bearing metallurgy to work with FA-4. Even the newest offering by International, the A26 engine, they are factory filling with CK-4, but only will fill with FA-4 per a request by the buyer. Just was involved in a webinar with the lead engineer on that engine and the CK-4 / FA-4 thing was discussed. I got the gist from what was being said, that they prefer the CK-4 over FA-4 for maximum engine life, but recognize that FA-4 would offer a edge on fuel economy. As a commercial truck owner, that says it all. I will only concern myself with CK-4. Risking a $30,000 engine with FA-4 in the hopes that I can save a few hundred a year in fuel. Not the risk I am willing to take. I can actually save more in fuel by better driving practices, lower rolling resistance tires, better gearing, and other things more than any FA-4 is ever going to be able to deliver. FA-4 is a solution in search of a problem.
I know I have run my first complete OCI on my Detroit 60 with Delvace Extreme 10w30 CK-4 and was very pleased with the results. A slight down tick in all wear numbers by a few points and a little lower oxidation. Viscosity remained totally unchanged. A solid performer. Still same 2 qt oil consumption in 20,000 miles as previously with CJ-4.
I've noticed in the past you've been partial to Schaeffer, is there a specific reason you've switched up? They have a few different flavors of CK4 10w30.
Just curious more than anything
