I've always run dino oil in the car, albeit maybe not always the best
viscosity for the temp range. Right now running 10w-30. Oil temps have
always been the same, with the temp needle never getter past maybe 1/4 to
1/3 from the left of the gauge (can't remember that temp at this point).
Yes Bernie, same story, different day. I've hesitated on addressing the
issue given the effort/money factor to accomplish said goal. Also heard that
replacing the seals only does not always fix oil consumption problems.
Aggravating the situation...older the car gets the less sense major work
like this makes. And like I'd mentioned...only times I ever see visible
signs of oil burning is on start up and these three long term, traffic
related idleing excercises.
