While driving up a capable off-roader up a mountain and driving an economy car to work may sound like drastically different tasks, both require a good, working vehicle. In both instances, you should make sure that your fluids are topped up and within their respective lifespans, your brakes are in good working order, and that your vehicle's consumable parts are replaced at the prescribed intervals. Whether you're driving through the Rockies or driving thru Starbucks, proper maintenance on your vehicle will decrease the likelihood of a major failure occurring with your vehicle, and also give you piece of mind that your vehicle is ready for the task ahead; whatever that may be.
