I have two track days and many mountain road miles on my GT350. I pulled out 38 ML of oil from the passenger side and the drivers side was fairly dry. Does that seem like a "normal" amount or less? The oil is fine and is right at the top of the 1st cross mark of the dipstick. I "guestimate" about 4500 miles worth of driving and only 1 oil change in between. TIA.
