You can not trust the factory gauges. They are glorified idiot lights basically. For example, the oil pressure gauge your refering to is an on/off type of deal. When your truck has 8psi of oil pressure, the needle will move. When you go less than 8psi, it goes to no oil pressure. The needle moves only because of a little ohm resistance thing in the wiring designed to move it so it looks like your pressure is going up and down, but it actually doesnt show whats going on. 10 psi of oil pressure will read the same as 50psi on those gauges.
I would recomend to all to buy some real gauges, these will only show you if something is seriously wrong.
For instance my water temp gauge doesnt even get past the long line before the C for Cold, doesnt even cross that, and my water temp will be 190*
