ENGINE MAINTENANCE

Engine maintenance is vital to keep your car or truck operating at peak performance. It also impacts the longevity of your vehicle's engine. Trust the experts at Mr. Automotive to help you protect your investment. Call us at 520-625-1500 or visit our shop in Green Valley 85622.

These are some of the engine maintenance services we offer.

Diesel
Although diesel engines don't require tune-ups and tend to last longer than gasoline engines, they do require regular maintenance. Typical maintenance tasks include:

  • Changing the oil & filter
  • Changing the air filter
  • Changing the fuel filter
  • Bleeding the fuel system
  • Draining the water separators
  • Refilling the urea injection system

You can count on the experts at Mr. Automotive to help your diesel engine last a long time.

Fuel Injection
Fuel injection is a system for admitting fuel into an engine. Since 1990, fuel injectors have completely replaced carburetors as the primary means of getting gasoline into the engine. A fuel injector atomizes the fuel by forcibly pumping it through a small nozzle (under high pressure). Failure of the fuel injection system means poor performance and ultimately destroys the engine. Make sure your vehicle's fuel injection system is maintained properly. For all your fuel injection maintenance and replacement needs, call 520-625-1500 or visit Mr. Automotive today.

Ignition
An ignition system is a system for igniting (using an electric spark) a mixture of fuel and air in a gasoline engine. A properly working ignition system means a properly starting engine and high performance from your car. For all your ignition system maintenance and replacement needs, call or visit Mr. Automotive today.

Ignition Wires & Cables
Ignition cables also known as spark plug wires are an important part of your car's ignition system. They transfer the spark from the ignition coil to spark plugs that ignite the mixture of fuel and air. The mixture starts the engine. Over time, ignition wires and cables get weak and break down. This makes it impossible for the spark to reach the engine cylinders. This results in the engine misfiring. The car will eventually fail to start. If it does start, it will run poorly. Common symptoms of faulty ignition cables and wires are: poor gas mileage, engine misfires, engine light is on, and engine may vibrate. If your car needs new ignition cables and wires, call or visit Mr. Automotive in Green Valley, AZ 85622. Here, you will have the wires and cables changed by a top-rated mechanic.

Spark Plugs
A spark plug delivers electric current to the combustion chamber from the ignition system. Spark plugs that haven't been changed for a long time can cause ignition problems. At Mr. Automotive, we have automotive experts who will check and replace your spark plugs. For all your spark plug repair or replacement needs, call 520-625-1500 or visit Mr. Automotive today.

Oil, Lube, and Filter
To keep running smoothly, your car highly relies on oil, lube, and oil filters. Oil helps in lubricating, cooling, and cleaning the internal engine components. With time, motor oil becomes contaminated. Your car needs an oil, lube, and filter change every three months (or 3,000 miles). When it is time for a lube, oil, or filter change, take your vehicle to Mr. Automotive in Green Valley, AZ 85622.

Check Engine Light
No one likes to see their car's "Check Engine" light come on. The light could mean a costly problem, like a bad catalytic converter, or it could be something minor, like a loose gas cap. At Mr. Automotive, we can pull the code and diagnose the problem for you. Give us a call at 520-625-1500 or stop by the shop for our expert assistance.

I have used their service for several years now and have always had the most professional courteous service. If there is a problem they go out of their way to correct it for little or nothing. They are very honest and you can depend on them.


-Dennis P.

Outstanding integrity and professionalism. I had not experienced this kind of integrity in a long time. My car problem was mice eating the electrical wires which required finding the breaks and resetting the codes. No surprise charges.


-Anthony O.

Very helpful, professional service. Diagnosed and fixed the problem quickly and efficiently. I would highly recommend.


-Jocelyne C.

Five star service! I was very appreciative of their ability to get me in and out of the shop quickly. I arrived needing a new battery, but had an appointment 45 minutes out... they let me pull right up to the bay and got started. Inside the shop is a great place to wait:) it's set up like a living room, so lots of comfortable seating... there's even a shop dog named Toby that comes to visit. If I need work done again and I'm in the Green Valley area, I'll definitely use this shop again.


-Nikky P.

Excellent service. I dropped my car off for inspection. By the time I got home, they called me with an estimate and said they had the part on the way. Quoted me a price and did not try to upsell me. They said the car would be done the same day and it was. Awsome,friendly service.
