One thing that we specialize in here at K&M Auto is performing oil changes. There are a lot of places out there that offer oil changes, but none of them can match our speed or effectiveness. A lot of people don’t even know why their vehicles require oil to run properly, and they will often neglect to have it changed until it is too late. Oil is the lifeblood of any car engine. It acts as a lubricant for all of the moving metal parts that are constantly coming into contact with each other. Without a healthy supply of lubricant, these metal parts will rub together, creating tons of friction. All of that friction makes for a lot more heat.
Eventually, the heat will become so great that the metal parts actually fuse together, rendering your engine useless. Unfortunately, oil does not last forever and must be replaced every few thousand miles. Oil is circulated through a filter and into all of the different parts of your engine. It then exits the engine and enters the oil reservoir or sump pan. The oil in the reservoir is then sucked up through the oil filter, and the cycle repeats itself.
As the oil moves through the engine, it picks up tiny particles and debris. The filter will screen out the larger particles, but over time your oil will continue to get dirtier, which will make it a much less effective lubricant. Changing your oil on your own can be a frustrating and extremely messy task. We can change your oil for you quickly and professionally, and you won’t have to deal with cleaning up any oil spills.
With a K & M Auto Repair Service oil change or any other service, you’ll receive a Touch® Courtesy Check. We’ll look inside, outside, under the hood and underneath the car, then explain the findings and give you a written report.
While you’re there, let us perform a Touch® Courtesy Check, which includes a visual check of the following items:

Most cars on the road today use multi-grade oil — one that can work efficiently in cold and hot weather. A multi-grade oil is rated by two numbers, such as 5W-30.
About the oil classification system.
Each engine oil comes with a classification indicating its viscosity, which is its friction or resistance to flow. In a multi-grade oil, the first number indicates how the oil will flow when it is cold. The lower the number, the lighter the oil and the better it will perform at lower temperatures. The second number indicates the thickness of that same oil at high temperatures. For example, a 5W-30 oil will flow as a 5-weight oil at zero degrees Fahrenheit and as a 30-weight oil at 210 degrees Fahrenheit
Why viscosity is a concern.
During cold starting, only a small amount of oil is present in the upper parts of engines. To lessen the friction when upper engine parts, such as the valve train, pistons, overhead cam and cam bearings, scrub against each other, a lower viscosity allows the oil to reach the components more quickly.
Why 5W-30 and 5w-20 oils are so popular.
Many vehicles today leave the factory with 5W-30 or 5w-20 engine oil. Vehicle manufacturers recommend them because they are lighter oils that perform well in a range of temperatures and help improve gas mileage.
Not all motor engine oils are 100% petroleum. Synthetic oils, which are primarily chemically compounded lubricants, are also available. They can provide:
Which oil is right for your car?
The simplest and safest way to find out is to check your owner’s manual…or talk to your Midas mechanic.
Oil filters are designed to trap foreign particles suspended in the oil and prevent them from getting to the engine bearings and other parts.
Your vehicle relies on a variety of fluids to operate its brake, steering, transmission, engine cooling and other systems. When these fluids become degraded or are at incorrect levels, damage to other components may occur…so always follow the manufacturer-recommended service schedule.
Automatic Transmission Fluid
This is typically an oil-based fluid used in a transmission that lubricates and cools the transmission and provides hydraulic pressure to shift gears automatically.
This is the hydraulic fluid used to transmit pressure through the brake lines in a brake system providing stopping power and protecting hydraulic brake components from internal corrosion.
This is the mixture of water and antifreeze used in an engine cooling system to dissipate heat and maintain the engine’s temperature throughout its operating range.
Starting & Charging
The battery starts your car, powers on-board computers and supplies emergency power needs. A weakened battery causes stress on alternators and starters, especially during extreme temperatures. Let Midas test and inspect your battery regularly.
Clean air filters can increase engine performance, boost fuel mileage and reduce engine wear. Cabin air filters can minimize airborne contaminants in the passenger compartment and improve heating/cooling efficiency.
Touch® Courtesy Check
The Midas Touch® Courtesy Check is fast, efficient and covers many items on your vehicle’s preventive maintenance schedule. We’ll conduct a visual check, looking inside, outside, under the hood and under the vehicle, then provide you with a written report.
