Without knowing if it was completely full since you got it used you can't assume yet that it is burning oil. I found out during my last oil change when leaving that it took 2 quarts of oil low to set off the sensor. I went back to the dealer and they added a quart which shut off the light, however it still read low and took just about another full quart to show as full. I asked how many quarts were put in they said 7 and it hold I believe 8.8. Depending on the mileage on the car I would pay for an oil change as I feel that the 15k intervals is insane. I did one at 1250 miles, one at 3k miles and will do another at 7k.
