I have a 2005 GMC envoy and i keep up with the maintenance on it but for some reason whenever i turn it on the oil light comes on and the gauge reads low and when I'm driving and I get up to 75 evrytime it dings and the gaUGE READS LIKE 60 when its normally a little over 40. Any help is greatly appreciated.
