Some Of The Automotive Maintenance, Repairs & Services We Offer


At K & M Auto Services, we do auto repair the way it is meant to be done, with honesty and integrity. We own several auto repair centers located throughout Portland, and our team of professional mechanics is trained to repair any foreign or domestic vehicle model. So, no matter what vehicle you drive, you can rest assured that it is in good hands at K&M Auto. From repairing transmissions to performing routine, scheduled maintenance, we are equipped to handle any vehicle issue.

Vehicles used to rely on carburetors to supply the fuel necessary for combustion, but not too long ago the carburetor was replaced with the fuel injector. Fuel injectors improve your vehicle’s fuel efficiency, make your engine run smoother and reduce the amount of harmful emissions produced when you drive. A fuel injector provides a precisely calculated mixture of gasoline and oxygen to your engine. Even with oxygen levels fluctuating wildly, a fuel injector can quickly supply your engine with just the right amount of gasoline that it needs for combustion. There is a lot of heat generated in the engine, and over time carbon residue can build up on your fuel injector nozzles. This residue can interfere with its performance and diminish the fuel efficiency and performance of your vehicle. Rusty gas lines and nozzles can also result in clogged or inefficient fuel injectors. There are a lot of small, moving parts in a fuel injection system, as well as electrical components. If these parts are damaged or not maintained, then your engine’s performance and fuel efficiency will suffer.

At K & M Auto Services, our hardworking mechanics can repair or clean any fuel injection system. We will eliminate any rust on your nozzles or fuel lines, and we will make sure there are no leaks in your system. If it is a problem with your fuel injector’s electronic components, we can take care of that, too. If you have noticed your engine misfiring, a drop in your car’s fuel efficiency, or other signs of poor engine performance, it could be a sign that your fuel injector is dirty, clogged or leaking. If your car is exhibiting these symptoms, bring it to one of our auto repair centers in Portland and we will get it back to normal promptly and professionally.

With a K & M Auto Services 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:

  • Engine air filter
  • Brake fluid
  • Power steering fluid
  • Automatic transmission fluid
  • Coolant/antifreeze
  • We’ll also walk you through your vehicle manufacturer’s recommendations for replacing these vital fluids and filters.

Oil Change – More than You Wanted to Know

Engine Oil
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.

Synthetic Oils
Not all motor engine oils are 100% petroleum. Synthetic oils, which are primarily chemically compounded lubricants, are also available. They can provide:

  • Higher viscosity stability over a wider temperature range
  • Reduced oil thickening
  • Reduced wear and increased load-carrying ability.

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
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.

Brake Fluid
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.

Air Filters
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.
