Oil pressure Gage= bad milage
My oil pressure Gage is of the read out high but there are no driving problems what so ever so I assume that it is just broken. My question is would this reading mess with some other sensor that would get me extra bad milage I mean I got 5 less mpg with zero mods. Also how can I fix my Gage and what ever else might be wrong. It is the straight six. My fluids are all fine. ThAnks

Your oil pressure guage sender is right next to your oil filter and they are known for going bad and/or developing leaks. Check that out as a possible cause for your guage not working. It is not connected to any of your sensors so it won't cause mpg to go down. My guess for that problem is that it is just time for a good old fashioned tune up.
