Although neglecting to perform automotive service may seem insignificant, it can have serious implications. The majority of car owners do not understand the importance of regular maintenance for their vehicles, which contributes to many problems affecting an owner's economy in both financial and time related areas due to decreased fuel efficiency, increased costs for repairs and extended periods of down time. In this article we are going to discuss how neglecting to maintain your vehicle affects you financially and with regards to time and why consistent maintenance of your vehicle is such a crucial factor.
The Impact on Fuel Efficiency with Neglected Repairs
Neglecting repairs on a vehicle will cause its fuel efficiency to drop dramatically. Neglect of parts results in those parts functioning improperly resulting in higher fuel consumption.
For example:
A clogged air filter reduces the amount of air that is supplied to the engine; therefore, the engine works harder and the fuel efficiency drops up to 10%.
The worn-out spark plug causes an incomplete burn of fuel, and thus leads to lower gas mileage (approximately 30%).
In addition to affecting your overall driving experience, neglecting small repairs will increase your monthly fuel costs to far beyond what they would normally be. By keeping up on maintenance, you'll have an efficient running vehicle that will save you money each month when you go to fill it up.

Rising Repair Costs
If you let problems get worse by ignoring them, they can eventually turn into very costly problems and what started out as a relatively inexpensive fix could end up costing you a lot of money.
Consider this:
An oil leak may appear minor, however, failing to address this problem will lead to major damage to your engine. Repairing a small oil leak can begin with a bill as low as $100, yet a replacement engine is estimated to be over $4000 when the issue goes unaddressed.
By regularly inspecting your vehicle you can identify these types of problems early on in the process, providing a solution for affordable repairs. Delaying until the last minute increases the likelihood that you will incur higher costs that could have been avoided through preventative action.
Increased Downtime
Vehicle downtime as a result of neglecting to perform necessary vehicle repairs will also increase lost vehicle use time. Once your vehicle is unable to run due to lack of maintenance you may experience an extended period of lost vehicle use. Vehicle downtime can have significant negative impacts on individuals with jobs requiring daily or regular commute trips (e.g., delivery drivers), where even one lost day may reduce the opportunity to earn wages or other benefits.
There are several consequences of down time (or lack of a car), including:
Losing income, especially to those who have to be away from home often due to their job (traveling); if a person's car breaks down one day they will miss out on potential opportunities and/or may lose money.
Being a burden to family members; many people depend on their car to run errands every day, to take kids to school, or in case of an emergency.
By keeping your car well maintained, you will have less chance of having a break-down unexpectedly, and your vehicle will remain reliable and available when you need it.
The Importance of Regular Maintenance
Regular maintenance is crucial in order to avoid any additional costs from repairing issues that arise from neglecting to perform necessary, timely work (deferred repairs). Regular maintenance will include typical maintenance items such as oil changes, tire rotation, etc., and inspection for proper function and safety.
The following are some of the most common maintenance services:
Oil changes every 3,000 to 5,000 miles to maintain a well lubricated engine with longevity.
Tire rotations every 5,000 to 7,500 miles to maximize tire life and promote even tire wear.
In addition to extending vehicle life, adhering to a predetermined maintenance schedule allows the owner to detect any issues prior to escalating into expensive repairs. Most automobile manufacturers have created service schedules to help vehicle owners stay on top of their vehicle’s maintenance needs. In the end, sticking to the manufacturer’s guidelines can save you money in the long run.
Understanding the Long-Term Benefits
In addition to saving money in the short run by performing regular maintenance and making timely repairs, there are benefits that will help keep your vehicle running strong over time. Your vehicle will last longer if it is properly maintained and serviced regularly.
Also:
Reliable vehicles provide an enjoyable and stress-free driving experience when a vehicle runs reliably without unexpected failures.
Well-maintained vehicles typically hold their value longer, which translates into higher resale values for them as well.
Finally, the many advantages of proactively taking care of your vehicle’s repairs and maintenance far exceed the negative consequences of ignoring this important aspect of vehicle ownership.
The Bottom Line
Regular auto maintenance may help prevent costly expenses that are associated with neglecting your car (e.g., higher fuel costs, increased repair costs and lost time). Routine maintenance will also help you save money and time by identifying potential problems early on.
It's obvious that taking care of your vehicle requires ongoing effort. By spending money today on your vehicle, you can spend less money down the line and have an overall better time driving your car. Today, saving dollars and cents is as much about being financially responsible as it is about having a comfortable and reliable way to get from one place to another.
