This is the 1st time I've changed my own oil on this new car....been taking it to the dealership. No this isn't the 1st time I've ever changed the oil on a car, I've been changing it forever on cars and trucks of older models. Somehow though there are no signs whatsoever of light oil droppings or runs like my older cars so I've looked all over and nothing to resemble a plug...no regular looking oil pan with gasket seal that can be identified either??? Anything would be greatly appreciated..BTW this is a 2007 Mazda 3 2.0.
