i usually see my oil pressure in my 2007 trailblazer at 40. Today i noticed it was above 40 and almost to the next number what can cause this?
Oil sending unit is bad or oil pressure is high. Have it looked at.
have you checked the oil level?
Yes oil level is normal. I have also been smelling a rotten egg smell. Oil pressure is a little below 60 now used to run about 40
