The Evolution of Automobile Maintenance
Cars used to require a steady stream of maintenance, from mufflers to shocks, not to mention various forms of rustproofing. However, it seems that many of these components are becoming less needed due to advances in quality control and engineering. This raises the question: why is this the case, and is it due to better workmanship or simply due to better engineering?
Advancements in Quality Control and Material Science
Quality control has significantly improved over the years. As a result, the understanding of component lifespans has also advanced. Such improvements mean that non-essential maintenance items like rustproofing are becoming less critical. For example, bodies are now better designed, with fewer areas susceptible to corrosion, and factory-applied rustproofing ensures that the vehicle remains protected from the outset.
Another factor is the cost-effectiveness of using better materials. It is far cheaper to use higher-quality steel for exhaust systems and shocks, rather than replace items due to leaks or inefficiencies. This trend means that even if parts do eventually need replacement, their lifespan is longer and their performance remains more consistent.
The exhaust system, for instance, has a longer guarantee now, making it more cost-effective to use better steel. Shocks, too, have improved in design. They no longer leak or lose efficiency as quickly, which means less frequent replacement. In my youth, shocks had a short lifespan and would leak, necessitating a complete set overhaul. However, modern shocks are efficient and last much longer.
Modern Cars and Their Lifespan
The overall quality of modern cars is indeed better, but the material quality has also declined somewhat. The best materials aren't as optimal as they once were, while the average components are a little better than in the past. This counterintuitive decline in material quality hasn't detracted from the overall quality of the car, thanks to advanced manufacturing techniques.
Moreover, the appearance and longevity of cars are much better. Cars that are older typically show minimal signs of rust or damage. They are often in such good condition that it is often not worth the expense of repairing them, especially given the costs involved in regular maintenance and updates like brakes, tires, and registration fees.
In the past, cars required frequent maintenance. However, since the year 2000, most components outside of brakes and tires have remained unchanged. Workshops often advise changing parts prematurely out of habit, but this may not always be necessary.
Disputing the Argument Against Maintenance
It is crucial to challenge the notion that cars do not need certain components like mufflers, shocks, and rust coatings. Cars still rely on mufflers for their exhaust systems and shocks to provide a smooth ride. Rustproofing, although now included in paint, is still a critical component in protecting the car’s body from corrosion.
The advancements in modern engineering and automation have resulted in better overall design and reliability, leading to less maintenance. However, this doesn't mean that regular maintenance is less important. The argument that everything is fine with the current state of maintenance might be misleading, as regular service is still necessary to keep the car running well and to catch any potential issues early.
To drive home the point, I recently replaced the mufflers and shock absorbers in my 2006 Mustang. The next logical step? A paint job. This example highlights that even with improved engineering and materials, some parts will still need periodic replacement, such as in the case of the paint job to maintain the car's appearance and prevent new corrosion from starting.
Hopefully, this article has shed light on the evolution of automobile maintenance and why certain components might seem less critical now, due to better engineering and quality control. It also serves as a reminder that regular maintenance is still essential for keeping your car running smoothly and safely.
