Engine Mechanical problem
1994 Chevy Silverado V8 Four Wheel Drive Automatic 379000 miles
I've been getting low oil pressure for about 2 weeks now. For the most part on the highway it is a little low, approw 25, but at an idle goes to almost 0 and the light comes on. In the morning it would take about 10 seconds to get any pressure. Changed the sensor for the gauge and checked with a mechanical gauge no help. Did an oil change and got pressure right away, and good pressure but that went away after an hour on the highway I got off the pressure went to about 2 but when I got into the gas it would go up. So I pulled the oil filter and the new oil was very dark and thin but the oil on the dipstick still looked new. Engine was running good when in the gas and was ideling OK.
