Because of the potential for damage to the motor.

Everything I read tells me there is MDS on my 2023 Tradesman hemi. I’ve never heard/felt it kick in, but I just figured it was too subtle for Me. i just heard it on someone else’s truck,and now I’m sure… mine does NOT have it. Am I losing my mind? I was gettin* tired of using tow/haul and...

I read somewhere that this new bore tech went through durability testing and still had the cross hatching, and no lip, after a lot of miles. I get the feeling the Bores will last a really, really long time.
