Also seeing as I can run it for a long highway run (like my trip to Orlando last time) and no oil burning smell or anything but I have to check it when I fill up because it's gone down a bit. It goes hand-in-hand with the miles driven, doesn't matter if it's 3 months between changes or 2 weeks because of a long trip.
next time you are driving at night check, take off hard and watch your side view mirror.. i always get a small puff of smoke when the RPMs first jump, but its only noticeable at night. only fluid that ever needs to be topped off is the oil, so I assume thats what it is
