No temp change means the engine is running at the optimum temp for this type of motor. 0W40 is only needed for extreme low temp startups. Most Chrysler dealers down south now use 5W40 Pennzoil as the standard oil change.
I change every 10,000mi. Oil test after each change comes back as pristine. All depends on the additive package. I use LIQUI MOLY 5W-40 LEICHTLAUF HIGH TECH in the N/a for last 70,000mi. Most popular brand in Germany over Mobil & Castrol. Tops among Audi and Porsche drivers.

SRT gets Amsoil 5W40 Euro Formula every 10,000mi. And always use the designated fleece filter. Paper filters have been shown to start disintegrating after 3000mi.
Also notice all the 5W40 brands designated under spec 229.5...

My N/A looks like that after 110K. All it takes is Seafoam every other oil change!
