Low Oil Pressure - Engine Loses Power
I have a 2005 F150 Lariat 4X4 with 127,000 miles and the 5.4 motor. Twice in the last 3 weeks I have had a loss of engine power and the Low Oil Pressure Light came on, the Oil Pressure Gauge was at the low position and the engine light was on. I was in stop and go traffic both times going less than 10 mph and pulled the truck to the side of the road. It didnít have any power but I donít believe the engine stalled because I still had power steering and only the oil and engine lights were on. I failed to look at the tachometer to confirm this because I was concerned about the low oil pressure issue and I was in an outside lane each time and basically just turned the wheel and was to the side of the road. I immediately turned the engine off and checked the oil and it was in the safe zone on the dipstick. When I restart the engine it starts up with good oil pressure and runs fine. I change the oil between 3,000 and 5,000 miles and started adding Lucas Oil Treatment about a year ago because it consumed about a quart of oil every 2,000 miles. The outside temperature was 15 degrees or less both times this has happened. Also about a year ago the truck went into Engine Failsafe Mode and lost power, but at that time the low oil pressure light did not come on. I did not see an Engine Failsafe light these last two times but I didnít take much time checking things out, I wanted to get the engine shut down immediately. Any ideas what may be wrong?
