About a year ago, I realized we were going to need to invest in a new family vehicle. The car that we had was dying fast, and I was worried about my wife getting to and from all of the places that she needed to travel. We started looking around for different places to shop, and I found an auto dealer that was absolutely incredible. I worked with them to negotiate a fair price for the car, and I learned a few tricks along the way. This blog is all about negotiating effectively with an automotive dealer, so that you don't end up with buyer's remorse.

Although you hear that you should change your car's oil periodically, you may keep putting it off. However, not changing the oil could backfire on you, costing you both time and money if your engine becomes damaged by the old oil. Below are four reasons why neglecting to change your car's oil regularly can be hazardous to your engine's health.
Gears Are Worn Down by Friction
From the moment you start your car's engine until you shut it off, the gears are working hard. They rotate together at high speeds to keep your motor running and allow you to travel where you want to go. Because of the high speeds at which they come together, a lot of friction is produced that could eventually break down the teeth. When the motor oil is fresh, it provides a thin coat of lubricant that reduces the amount of friction to let the gears rotate without damaging them.
When the motor oil is old, it becomes thick and is unable to fully coat the metal. Eventually, the friction wears the metal down.
Old, Thick Oil Makes the Engine Sluggish
When the gears become worn down from lack of lubrication, your engine will not be able to run efficiently. Eventually, as the teeth of the gears become damaged or break off, this will be unable to keep the pistons and other moving parts from working properly.
The pistons inside your motor normally move up and down at a steady rate, causing the fuel combustion that keeps your engine running and your car moving. However, when the oil becomes old and the gears no longer work properly, the pistons will start to jerk and become unable to fully ignite the fuel. This will make your engine feel sluggish when you try to accelerate.
Metal Moving Parts Get Rusty
Motor oil does more than just lubricate your engine's internal moving parts. It also helps protect them from moisture and corrosion. When the oil is fresh, it fully coats the metal interior of the motor. This coating acts as a shield from oxidation to keep your engine from rusting.
However, when the oil becomes thick and burnt from extended use, it no longer has the ability to coat the engine. This puts your motor at risk for rust and corrosion. Eventually, the engine may deteriorate to the point that it seizes up.
Engine's Interior Starts to Warp
Rust and corrosion are not the only types of damage your engine can suffer when you keep running old motor oil. Oil also provides protection from the excess heat that your motor produces while running. Between the constant friction of the gears and the combustion of fuel, your engine is exposed to very high temperatures. When you keep your oil changed, the new oil becomes thin under these conditions. The molecules in the oil then absorb the heat, pulling it away from the metal.
When oil gets old, it loses its ability to pull the heat away from the metal in the motor. When you continue to drive your car, the constant exposure to high temperatures will start to melt the metal pieces in the engine, causing them to warp. When the pieces become warped and misaligned, they will no longer be able to fit together to keep your engine running. The motor could seize up, necessitating extensive and expensive repairs.
If it has been a while since you last changed the oil in your car, you could try changing it yourself. However, if you do not have the time, desire, or comfort level to do this, take your car to an automotive shop so they can change the oil and replace the filter for you.
