gernal questions

  1. General
    I have recently bought a 2003 Trailblazer LS 2WD I6 non-extended. I was noticing that it ran 2500-2700 RPM doing 60 MPH on the highway and 3000 RPM at 70 MPH. I was wondering it was normal. Or if that it was unusually high. All responces and answer will be greatly apperiated.:hail:
