Oil

[MSL]

Ok i have had to add a quart of oil about a month or so after my oil change and now i had to add a half a quart just today. weird thing is where is it going its not leaking i have checked for that and its not burning oil since i would smell it. could it be caused by the oil breaking dow from gas being in the oil. i need to change my fuel pump since that was one suggestion to why i have gas in my oil. but i just wonder where the oil is going if its not from the gas. any ideas.?
