Mobil One and other oil manufacturers recommend checking engine oil levels before driving your vehicle, when the oil is still cold. However, some manufacturers will recommend checking the oil after you've warmed up the engine, so check your owner's manual to find the specific recommendations for your vehicle.
Oil: Oils well that ends well.. When starting a cold engine let it tick over for a few moments to circulate the oil-most engine wear occurs within the first minutes of switching it on. Oil is an often overlooked part of the engine but more internal friction = lower power and more heat produced. too much oil and it will get into places it shouldn't and could start seals leaking or cause other damage the engine ie:- burning oil/broken seals/piston rings. Too little oil will cause premature wear. Always change the filter with the oil.
