So far the best oil I've ran in my 2024 and 2006 PSDs. Survives the shear!
I've ran this oil originally in my 2006 6 liter PSD, and it survives the typical shear that this engine is famous for under normal drain intervals. My 2024 6.7 HO really likes it and gives me great mileage. This is the mostly synthetic flavor, I'm trying the full synthetic currently to see if there's any improvement over already awesome. I believe so far this oil also outperforms Liqui-Moly Special Tech AA 10w30 diesel oil as well in my 2024. Schaeffer makes some truly impressive lubricants!

Best oil I've found for a 6.0 Powerstroke
As a retired Ford Technician I am very pleasantly surprised by this oil. I have ran Motorcraft and Valvoline for decades. But this oil is amazing actually picked up 2mpg in my 6.0 powerstroke with this oil. Now that I am planning to open my own shop this will be my go to Diesel oil and will run in my personal truck.

Oil is for my diesel
Typically the oil in my diesel turns black shortly after a oil change. (this is normal) The Schrieffer oil is not doing that as quickly. Very happy with the oil. I will review it again at 4000 miles during the my next oil change.

Amazing for powerstrokes with HUEI injectors.
I use it for my 2005 6.0l powerstroke f350. Amazing product, the engine fires right up cold starts hot starts does not matter. My new go to for oil. I bit more money but I don't have to run a Lucas additive anymore.

Not 100% Synthetic
One thing to point out this OTR 10W-30 is (0711CK4-006S) - which is a Semi-Synthetic... The (9012) OTR 10W-30 - (09012CK4-006S) is the 100% Full Synthetic - similar to the formulation of their 9000 5W-40 Full synthetic... I did not realize this until now - I spent 30min looking over Schaeffers website & finally found 2 types of OTR 10W-30... Just wanted to point this out - so buyers who prefer a 100% Full Synthetic was not mislead...
