Or should I say, the "30" flowed better at cold start up.

because oils have viscosity components engineered into them to help them "adjust" to enviornmental changes, but the polymer chains that were part of the additive package  didn't do the job, or should I say they wern't able to handle the adverse temp changes so temp ranges were determined by engine designers and recommended to the public based on testing done at time of manufacture.

Well I know I've changed my cars oil in the dead of winter when the new oil was in a garage that was about 20 degrees and it didn't pour down the funnel too thin. More like molasses.


I know my oil is just as thick sitting in that 20 degree garage in my oil pan. And my old Jeep Cherokees lifters knew it was like molasses in the pan as well.

current synthetic oils do much better compared to petroleum based oils.  have you seen the current  5w-50 oils being offered..   they are a far cry better than there petro based counterparts

I remember doing the summer/winter switch, and I don't anymore.  But if I were worried, I would go toward a 15W-50 or 20W-50 in summer for an old, low clearance engine.  For the stuff we have today, in both oil and engines, the 5W-40 synthetic will do the trick.
