Reply to "Oil Pressure goes up and down"

Could be oil filter, could be oil gauge, could be engine problems. One suggestion - the only way to know for sure is to install a mechanical oil pressure gauge.

I had flaky readings in my GT5-S, sometimes decent pressure, sometimes not, and I couldn't really establish any pattern. I installed a mechanical pressure gauge in parallel with the stock one and notice that the two readings are as diffferent as night and day.

I've spoken to other people who have noticed significant differences between the stock gauge and a mechanical one. In the end, I left the mechanical gauge permanently installed since it wasn't hurting anything and seemed useful. It's hidden in the engine bay to the passenger's side of the engine screeen.

I'm a gauge watcher as well and it drove me nuts to see low oil pressure. Now I am much more confident and comfortable driving.

IMO it's the only way to know for sure...
