Did they put in a Mann or Mahle oil filter??  Any other brand could cause
the symptoms you described.

Subject: Summer Oil pressure drop + higher temperatures with oil error
(Was: Is 20w50 Oil OK in the winter?)

This new learning amazes me.

Here is something interesting. Last summer I brought Pokey in
for an oil change (yes I know I should be doing it myself but
oil changes are cheap and I find myself too busy sometimes)
and they inadvertently used 10w30. All of a sudden I saw a
drop in oil pressure (maybe to 20 psi on the highway), and
much higher operating themperatures. Hence I went out and
bought an auxillary oil cooler (as yet to be installed).

The season was ending, it got colder out and my temperatures
fell back into acceptable levels. The pressure did not come
back and I was going to look into this over the witer. I was
going to get the oil changed again (hence my original
question - If you did not read my previous post, I was
wondering about using 20w50 in the winter as that is what I
normally run.).

Now forgive me, my mechanical incompetance is surely
showing... but could the change in oil from 20w50 to 10w30
account for this drop in pressure and higher temperatures?

Thanks,
Chris
