New PC-12 Diesel Engine Oil in Development
Looks like the new PC-12 Diesel motor oil will be released in Jan 1 2027 and the big one could be reduced Phosphorous levels. Can't help but wonder if Ford is going to cry about that at the last minute leading to the release of this oil that it will increase upper valve train wear.
Some highlights that standout to me:
Aftertreatment systems (such as AdBlue systems, diesel exhaust fluid (DEF), and diesel particulate filters (DPF)) must achieve a longer service life. In the USA this will extend out from around 435,000 miles (700,00 km) to 800,000 miles (1,290,000 km)
We have seen reduced viscosities under the API FA-4 standard, where 5W-30 and 10W-30 oils are now common. Under the new PC-12 category, OEM’s are coming to oil manufacturers asking to provide even lower viscosity formulations.
Phosphorous limits will be reduced as part of the new category (Ford are you paying attention to this one)
Summary of (Advertised) Benefits:

Summary of (Advertised) Benefits:
What are the excepted benefits of the spec upgrade?
- Greater Heat Tolerance/Oil Drain Interval (ODI) Extension
- Better Oxidation Performance enables possible increase in fuel economy OR possible increase in ODI
- New Wear Test Ensuring Wear Protection
- Ensures wear protection of low viscosity oils and protection against liner scuffing
- Improved Aftertreatment Performance
- New chemical limits can extend service intervals and service life
- Lower Viscosity = Improved Fuel Economy
- Low viscosity directly enables fuel economy/ Greenhouse Gas (GHG) reduction

If you haven't seen this new video it explains alot of interesting info on oil especially I thought for turbo engines. It's long though, good thing for hotel internet.

Interesting article... looks like for extending OCIs, for more reduction in emissions and more effective, longer longer lasting exhaust aftertreatment systems and also looks like the HD market may see 20 weight oils for the first time.

I don't know why but I find his videos interesting. Glad choosing Rotella T6 "synthetic" as good chose for the turbo engine.

Lovely and it doesn't sound like they are interested in dual tracking either. As mentioned above FoMoCo is going to have a fit...

Lake Speed Jr. will also be the first to tell you that extended drain intervals and lower viscosities are purely an environmental ploy. They are NOT better for the longevity of the engine, but the EPA gives the OEs credits for specifying longer drain intervals and the OEs also get credit for even minor increases in efficiency which is why they are going to oil companies asking for thinner and thinner viscosities.
You can hug trees or you can have an engine that lasts a very long time, but you can't have both. New vehicles are becoming worse with every passing year now, and it's really sad.

I see some are stuck on old engine technology. Engines made today are nothing like their ancestors. Back then engines needed thick oil to help with shear strength as well as sloppy tolerances and mediocre machining methods. Today engine tolerances are so tight that thinner viscosity is needed, machining is super fine, and metallurgy has created some really good alloys that machine to very tight specs and fineness. Oil technology has also kept pace and exceeded some manufacturing with packages to increase shear strength while also building very thin layers. Oil of 0-20 today has shear strength up where 10w30 and higher used to be, and oil longevity itself has greatly increased. Back then you pop the top on an oil can, or stick the funnel in and dump it into the engine, Single weight oils were the norm, and getting 3K out of a change was the norm and changed often because the packages used didn't last long, but today, they have been greatly improved and last 2-3 times as long.
At some point engine oils will be going to 20 or 30K intervals.

doesnt stay tight tolerance as the miles pile up.
the thin oil is part of the miles per hour ratings that builders get ratings for
builders only need the motor to survive the warranty.

I have 181K on a 3.5 Ecoboost, other than the chain needing to be replaced soon, the engine is clean and strong and bet it is all well within new tolerances. Good oil will make an engine last a long time. Still looks like a new engine inside the cover. Still pulls like it's *** it on fire too.

Me too, if I ever get it.
Sure, engines long ago, like Rolls Royce, were hand built and were well machined. However, Today, they are all done by computer so consistency is there from one part to the next, where back in the day, they were machined with gauges and close enough to eyeball. Castings are finer too since the plugs are CNC milled, and automated sand molds on most of them now so they all come out the same. Vast majority of the milling and machining is done by computer and not touched by hand until final assembly, and even some of that is done by computer. Then they are fully broken in before they even leave the assembly line. This last part is key to their longevity, an improper break in of rings can lead to a short lived engine.
