I have seen on here where people are talking about oil temperature. None of the cars I have owned has ever had a guage like this. So I am going to ask: 1. where would you install one (I know the oil temp will vary based on where in the engine it is)? 2. How do you install it? 3. What should my oil temperature be? I have been looking into this for a while, but can not find any info on how and where to install one. Any help will be greatly appreciated.
