It looks pretty good for a break-in oil. Iron, copper, and aluminum are all wear metals and are expected to be higher on a break-in oil.Here are the results of my first factory oil change at 3700 miles. I'd be interested to hear your thoughts.
Nice! I'm looking forward to seeing some data from the Amsoil.I replaced it with the rec'd Amsoil 5w40.
You're correct. According to his UOA report, the oil had a 9.19 TBN. His oxidation was 8 and your oxidation was 9. The factory oil is dropping TBN pretty quickly, but the additive package seems to be holding up. I wouldn't want to take the factory fill to 10,000 miles, that's for sure.Yeah the TBN struck me as being low as well. If I remember correctly Matt H replaced his factory oil at around 1200 miles and TBN was much higher, maybe around 9?
There's only one recommendation from Amsoil and that would be Amsoil European Car Formula 5W-40 Classic ESP Synthetic (EFM). And no, it won't have the MS-12991 on the label.
So hopefully this is a just a stupid issue:
I don't see "Amsoil European Car Formula 5W-40 Classic ESP Synthetic (EFM)" available on amsoil.com, which currently reccomends "SAE 5W-40 FS Synthetic European Motor Oil." The only other European oil listed is a Mid-SAPS.
I imagine the full-SAPS (FS) is just the a rebranding of the "Classic" and the mid-SAPS is the "Improved." Anyone already address the issue? Or am I missing something
EFM is the only oil that is recommended for the 3rd gen EcoDiesel engine. You must be looking at a different model year. Look up 2020 Ram 1500 EcoDiesel and you will see the EFM.
So first oil change, FUMOTO valve to be installed.....
As you may know, oil drain plug partially above crossmember and messes are made in videos.
As you probably figured out, a funnel may help. I think I picked this one up in a set from wally world. Has a lip that sort of sits on some coolant lines.
Red Line 5w40 starts at 7 - it was just over 5 at 10K....TBN of 7 is high after 3700 miles. The oil had a lot of life left. Any TBN over 2 still has active additives neutralizing acids.
Most if not all oils drop TBN fast in the first x thousand miles of an OCI, the longer the interval goes on the slower the TBN continues to drop.Red Line 5w40 starts at 7 - it was just over 5 at 10K....
Of course this oil starts near 11, possibly higher, and is at 7 in less than 4K - be interesting to see how it changed over the next 4K. Whether it’s loaded with soft base overbased detergents, or whether it has a hard based core that suddenly slows the drop...
This is because most use a significant amount of soft based to raise the TBN - Red Line clearly has almost no soft based in their 5w40 blend.Most if not all oils drop TBN fast in the first x thousand miles of an OCI, the longer the interval goes on the slower the TBN continues to drop.
