Now: Check Gage/Oil Pressure Guage
Well, here's what I noticed tonight. Right when I started the truck, the 'check gage' light was on. Temp and Gas readings were normal. Battery was right in the middle. The OIL pressure was completely rock bottom. I just check the oil 2 hours before, and it was full. I did the automated oil check- says pressure is great (on the computer/console thingy) and had about 77% life in it. Hmmm...
So I started driving, and all of a sudden, the 'Check Gage' light went off, the the oil pressure needle shot up to the middle mark. Then it dropped to the bottom, light came on. It fluctuated back and forth like that couple times really quick- then, just stopped. The light went off, and the needle was in the middle. Soooooo... now I know what the culprit is- what's it mean?
Like I said- just checked the oil, it's up to max, and looks pretty clean for the most part. What would cause the needle to be at rock bottom, ONLY for the first 2 minutes of starting the car? It almost seemed that as the engine revved up to a certain RPM or speed, it started working fine. Any ideas?
Thanks guys!
