oil does turn black fairly quick.i guess some of it would depend on how heavy the oil is and also how hot you run the motor and good of a cooling system you have.if it bothers you try changing the filter between oil changes.that will help to keep it clean and give a fresh quart of oil to add to the could also try some of that engine flush 3 or4 times a yr.all cheap fixes that may help.i use one of micro screens you put on top of your oil filter to keep particles from flowing thru your oil.also you can go to lowes in the hardware section and buy packages of round magnets for a couple of bucks.i put six of them around the drain of my oil pan and tranny pan.remove them before draining oil and reistall.check the oil for all helps cheaply.good luck

What kind of oil? Many synthetics are black when they're fresh...

wide ring end gaps will make oil black a lot faster, there might not be enough combustion gasses getting through the gaps to notice an increase in crankcase pressure but in my experience there will be enough oil contamination to turn it black. Some of the ready to run nonfile fit rings today have some large gaps just to make sure they aren't going to butt when hot. JMO's Bob
