What do we mean by preventative maintenance is the key to vehicle longevity? It means replacing fluids and parts when they are worn by age or mileage, not waiting for them to bad first.

Whenever we have a customer with a 10 year old approximately 100,000 mile car and say they have never had to do anything to it, I just cringe. The vehicle has had some oil changes, but not all of the recommended maintenance, and it is just a matter of time before some major work needs to be performed or a major component or system will start having failures. Mechanical parts do not last forever, and a lot of them have done their job at 100,000 miles.

Age, mileage, heat and cold all cause deterioration of vehicle parts. Lines and hoses get brittle and will split open, fluids break down losing their lubricating and cooling properties and can suspend particles in them that can be abrasive to the system they operate in. Coolant loses its pH balance and becomes extremely acidic and will eat away at hoses, gaskets and metal surfaces. Belts crack and get brittle. Electrical components like relays, computers, alternator, starter, solenoids, and emission devices that are abundant on today's vehicles will wear out over time due to the unfriendly environment of heat and cold.

The life expectancy of a vehicle can vary greatly based on many different factors. But if you want a longer life expectancy in your vehicle, regular preventative maintenance is the key to getting the longest life out of your vehicle. Happy Motoring!
