How much oil did you have when you started your road trip ?

I change my oil seasonally - Thanksgiving Weekend (snow tires go on too) and usually in March when it's warm enough to work outside comfortably. As far as fluids on the X go....I always top off the coolant during these times and if I'm taking a weekend away in the summer, I check and top off to the *high mark*. In my opinion, and methinks MotorDavid too, ATF is the fluid that tends to disappear in the X.
