So my question is this . I have a1991 5.0. Has 106,000 no. Completely stock. My oil when cold and just started car is about middle of guage . Then as it warms up it goes down. Street driving is still pretty low. Around 1 to 2 notches above red. Then on freeway coasting is a lol highest and giving a little gas goes down a bit. Then when fully warm my needle sits on bottom on red or just above or below it on idle. Then bounces up a little bit then down . Was wondering if it is something internal. But thinking that the miles are low so maybe not. Or maybe it's a lol pressure sending unit. Any ideas?
