However, in high-performance or towing scenarios, upgrading to a 10W-40 can offer enhanced stability and reduced oil consumption under severe stress. Additive Technology and Modern Formulations Modern oils are complex chemical formulations designed to combat the specific enemies of the Hemi engine, namely deposit buildup and shear stress.
The oil must strike a delicate balance between providing a thick film to protect moving parts in extreme heat and remaining fluid enough to circulate quickly on cold starts. The advanced additive packages found in full synthetic oils are particularly beneficial for the 5.
