Boy!! you must not be on the Mopar Mailing List (MML). Slick 50 has been a
thread for over a week now. There has been anedoctal testamonial's about how
good it is and horror stories about how bad it is. The testamonials are
things like it reduced my water temperature by x degrees (what I always
wonder is when you have a thermostat controlling the water temp how do you
get a water temperature drop?) and the horror stroies are it plugs up the
oil filter and oil lines. The few independant & scienticially valid
analysis's of this type of stuff have generally concluded that is does not
hurt but also does no good.

Agreeded!!

The oil companies have had what 35-40 years of development work on
multi-grade oils? All there efforts go into these oils and the additive
packages are developed precisely to fight breakdown. I can't see how using
straight weight would be better for your engine, besides I do not think
there are any straight weights that will meet new car specs.

A fine choice!
