If you travel most of your miles on the open highway in a short period of time new modern cars recommend 5,000 - 8,500 mile oil changes. If your trips mainly are around town with a few high speed long trips do not exceed 5,000 miles. The handbook in your glove compartment will give you all the necessary information.

If your not sure when it was last changed, you should change it to be on the safe side. There are tests you can do for the oil, but it's cheaper just to swap it out for new. Also, don't use any fancy engine oil additives. Use better quality oil like synthetic or semi-synthetic.
Check the oil, if it's low add oil, and if it looks dark brown, it's time for an oil change.
Your oil should be changed every 3-5 thousand miles. So if you have not kept track of the mileage I would say if its been more than 4 months get it changed.
If it feels like its dragging then you need oil or get under the hood and check the oil stick
every 3 month
