Oil changes are need approx. every 3,000 miles. Its best to get a tune up. You can do it yourselfvery easy. Oil change: undo dran bolt, let drain, put back bolt to neccisary torque. Change oil filter and refill! Simple. fuel filter can be a little more tricky having to take more things off. Change spark plugs, maybe transmission oil/filter (its over looked more often but could be done every 10000 miles i think?
