My C5 FRC has 51,000 miles on it. I have owned it almost 5 years - bought at 37,500 miles. Have changed the oil faithfully. This will be the 6th season I will be driving it. What other maintenance should I perform. Car is stock with Borla exhaust. Plugs? Wires? Coolant?. Car runs well - 30.9 mpg last road trip - 300+ miles. Keeping car. No desire to sell.

 

Your coolant should've been changed, twice since the car was new. Your brake, power steering, and clutch fluid should have also been changed. I do the power steering and clutch fluid with a turkey baster bulb or syringe, every so often.

I'm assuming you've been changing your air filter. That should be done every 10-12,000 miles.

Check your owners manual for a complete schedule of maintenance items.
