I have strange problem on my Scag V-Ride Kawi FX engine. The oil has been darkening rather quickly, after only 25 hours it is almost black. Also it appeared to be rather low, almost empty on the dipstick. But when I drained the oil to change it I got almost 2 quarts out, which is what it takes to fill it. Is it possible for the dipstick to somehow give an incorrect reading? Also any thoughts about the oil darkening so quickly. It runs fine other than that.
