Finally found some oil for my 3.0.ED
Parks Auto has 1 gal. jugs for 34.99 each; While I prefer the 2.5 gal size, the 1 gal was all they could get in so I got some.
I talk to I corporate guy with NAPA Auto. He said Shell is saying production should be back to normal by September or October 2022. I don't like the other oils. Rotella T6 all the way.
I started with the recommended Mobil1 but quickly changed to T6. And then change the weight per the service update to T6 5w-40. I've got 128k. And using cetane for the last 47k. I just got a pesky recurring engine light related to the fuel rail sensor. It was replaced and that didn't change the issue. Diesel shop ran scan under normal operation and found that the pressures are normal. They think it is a intermittent open in the harness on the sensor signal or intermittent grounding. It will be hours of work to trace that out
