Well there'* a few inches of snow here already and it'* in the 20s. I always used to check my oil pressure and it was always basically on the 1st line above 40 on my particular gauge. Whether I was driving at highway speed or idling, the oil pressure stayed almost exactly
Does that sound normal that the pressure barely moved?
Also, now that it'* cold out, I noticed my oil pressure is down to about the line BELOW 40 at times, and when I'm driving it gets up past 40. Is this just due to the cold weather? (The shop might have also used 5W-30 a few weeks ago when they changed my oil.)
Thanks for the help, these questions may seem dumb to some, sorry.
