my 93 ford f-150 has a brand new mustang 302 in it .around 2000 miles. and the oil gauge reads normal with gas and low with out gas .when its low its where the neddle goes when its not running . i dont no what to do its not making any funny sounds and has plenty of power. some one please help ! alsowhile running the neddle always stayed in the middle and didnt move . now it moves from low to normal if you give it gas and then back to low if you let off the gas , low is in the red .
