It pretty much tracks the water temperature gauge plus about 20-degrees. It takes much longer to heat/cool than the water temp. I think that the highest that I have ever seen is about 220. It's not a very "fun" gauge to watch but I think that it does provide valuable info. Use the extra tap on the top of the oil filter flange for your sender.
Additionally, once you've got the gauge, you can use a switch to add other sensors to other locations (i. e. rear end, transmission, etc. )
