n Check tire inflation regularly: A book should be written on tire pressure alone. This is so important, for optimal braking, improved gas mileage, better ride....the list goes on. Check your manual for your tire pressure (or look on the inside of your drivers door jam—there is a sticker there, too). Make this a habit you do all the time. Use a tire pressure gauge or go to the gas station and check the pressure with their gauge.
n Know your engine oil life: A smooth clean engine will give you longer engine life. Keep track of your oil changes so you know how long yours lasts.
