Escalade oil pressure low when cold, ok hot.
I have a 2006 Escalade ESV 6.0 engine. Oil pressure low when first started.
Very low when temps get to freezing. But when warmed up, the pressure
rises. I thought the sending unit, but changing that didn’t make a difference.
Everything I know is pressure should go down when warm.
This has me stumped.
Changed to different oil and filter too just in case something wrong but no
difference.
