    I was able to find 15w-40 in 2.5 gallon bottles today. $75/bottle! bought two to cover me a couple changes.

      Not sure about the Duramax or Cummins engines but a VERY reputable Powerstroke builder said that almost all of the bad 6.7 Powerstrockes he gets in his shop have some sort of spun bearing. He says that when he has asked what oil they run all of them have said 15w40 even though Ford says to use 5w40. I believe the response he gets from the owners is that 15w40 is the only thing they have ran for 30 years in all their trucks and didnt know any better. The tolerances on these engines are super tight and needs 5w40 to lubricate everything properly.

      He did say that the majority of failures are from folks in colder climates that do the remote start several times while it is idling in the driveway which compounds the issue.

        I started running the tsc brand oil. It meets all the required specifications from Ford. Can get a 5 gallon bucked for about 60 bucks .

          Good info. I had not heard this, but I know not to deviate from specs on a motor where the long block is 10k...

          Dang, not bad. Full synthetic?

          I ended up finding oil. But I paid a premium.

            That's interesting. Duramax here, I personally haven't heard that or seen it in my limited forum browsing. I'm gonna do some digging. I've been running 15w-40 about 95% of the time for the 196,000 miles I'm at. Have used 5w-40 twice when I couldn't find 15w40.

              This builder specifically calls out just the 6.7 Powerstroke. He builds all the other Powerstrokes, Duramax and Cummins but didnt say a word about 15w40 in those engines so I assume the tolerances are not as tight. On the 6.7's he builds he actually increases the tolerances to avoid an issue, I have not figured out why Ford made the tolerances so tight.

                You mean precise??? And why are the others so sloppy?

                    Doesn't DEF have a shelf life?

                      I think he meant oil, but even oil has a shelf life. I'd imagine he has more than a few truck considering 200 gallons is enough for 500,000 miles assuming you can make it 7,500 on an oil change.

                      I am also struggling to find oil filters for my track car now too.

                        I haven’t seen rotella either. I don’t run it in my daily driver anymore. But everything else in the yard gets it.

                          Here’s a list of approved oils. Find a 5w40 (if that’s what you’re looking for) on the list from a reputable brand and you will be fine.

                              Your Jiffy Lube uses Rotella? Nice!

                              I wouldn't trust any of the quick lube places near me, minimum wage high schooler with $10k engine? No thanks.
