Few points,
I bought our van in June 14 and we just crossed 22k miles. I am about to complete the fourth Oil Change. The OLM doesn't come on until 9-10k miles.
We drive a lot at highway speed. I drive hard too. Not so much drag racing launches and stuff like that. The RPM range is there to use. Right?
As far as Amsoil price, the OE is $6.99 a quart and does indeed carry the Chrysler certification for my Fantastic Pentastar. This is not the $12 a quart stuff for Long OCI. The OE doesn't have a 25 k OCI. It's to be used with OLM's.
Thanks for the feedback!
