TSB TSB 18-078-16 - Engine Oil Viscosity Upgrade And Flash Enhancements

[BoostN]

Official TSB is attached here.

This bulletin involves reprogramming the Powertrain Control Module (PCM) and the Transmission Control Module (TCM). It also involves changing the engine oil with new 5W40 engine oil and applying a sticker to the engine oil filler cap. An addendum card will need to be added in the owner's manual

Soooooo....owners of a '15 should ignore this TSB then?

Thanks for posting this. For whatever reason, I did not receive anything from FCA, so w/o this forum, I would not know about the Rotella oil switch. I think I'll forgo the ECU Flash reprogramming. Somehow, I doubt it will either improve fuel economy or engine MTBF.

Forums are great source of information! Glad to have you here Terry.
