The car doesn't have floating needles on the gages, but once the car warms up a bit, the needle on the oil gage starts to move to the 1/4 position-but when we check the oil its fine. Had the oil changed like clockwork and this only just started to happen-checked all hoses too-what is causing this to move like that?

Hi there,

Get the oil pressure tested with a master gauge, this will give a true indication as to the engine oil pressure. you may just have a faulty sender or gauge, do this test first.
