I'll preface this post by saying I have no clue what I'm doing when it comes to working on my car. I can do basic stuff like change headlight bulbs, replace the battery, install wiper blades, and change a flat, but that's about it. Got my oil changed about two weeks ago and the mechanic told me that my dipstick was totally dry before they filled me up with new oil. Just checked my dipstick today, and once again, it's dry as can be. How the hell is that possible if I just got my oil changed so recently? Is my car leaking oil? There aren't any stains on the floor of my garage where I park, although I do sometimes get a burning smell wafting into the cabin of the car while driving. Could oil be leaking onto the engine block and then burning off? Help please. Oh, and I don't know if it matters, but the car is a 2003 Mazda Protege 5, which just hit 100,000 miles 3 days ago.
