2010 GMC Sierra crew cab 4x4 Z71 - low oil pressure
Is it normal for this sierra to run 39% oil pressure on the highway on cruise control and at
times 20% percent on idle in the city? Doesn't that seem too low? I took it to the dealership
and they said it was normal but it's hard for me to believe that.
Wanted to add that it's a 5.3 liter flex fuel and I recently got it's first oil change.
I have a 2010 sierra z71 flex fule 5.3 as well. although mine is lifted with 35" tires and 20" wheels. My oil pressure has never dropped that low. i would examine it further.
i have the same truck but a 2009 and must oil pressure never drops below normal in the city or on the highway i think your right and its not normal i think your dealership is trying to avoild a warenty claim i would take it to a independent sevice dealer. i hope this is a little bit of help
