So I have a 92 gt. My oil pressure gauge is stock and it's reading low. I did some searching and found that the stock gauges are pretty bad and notorious of giving false readings. The one thing is that when I drive my car hard and basically keep it at higher rpm the oil pressure will go back up to the middle of the gauge and give a perfect reading. But when I am just cruising and driving normally the oil pressure goes back down. Please help.... thank you! Also I checked the oil and it's at a normal level. It's 10w30 full synthetic.
