  • "Once again...I would not take my MERCEDES to anyone else!!! GF United is THE BEST and MOST HONEST!!!"

  • "My Experience with dealing with GF United Auto Service was fantastic. I have had bad experiences with other auto shops in the past so I really scrutinized the work done by GF Service was very happy with the work done. Gene Fleshler was knowledgeable, honest and patient. I now have all 2 of my cars under Gene?s care and feel confident that the cars are getting the services they need, not the services that the dealer recommends to fill their pockets. I would recommend anyone to put Gene through the test and let him prove his worth to you as well. "

  • "I have had problem with my Toyota Sienna brake for a long time. The dealer was not able to fix the issue. I took my Van to GF United Service and they did a wonderful job! They gave me a quick appointment and the work was done in few hours and the charges were very reasonable. I felt the owner is honest and very courteous. I would go back again and strongly recommend GF."

  • "Excellent service, excellent prices. Very accommodating and willing to take you on a short notice to get you back on wheels the same day. Will definitely return and for each of my 3 cars!! Best of luck, Gene!"

  • Should I consider using synthetic motor oil?

    Synthetic engine oils are produced through a synthesis process that takes very small molecules and assembles them into larger designer molecules with premium lubricating properties.

  • Time for brake service?

    There are several warning signs that your vehicle can give you before your brakes may reach the point of potential failure or extensive repair. Simply using your sense of hearing, sight and touch may alert you to a potential problem.
    Here are some of the common questions you should ask yourself concerning your vehicle’s brake system:

    • Does your brake warning light come on when you are driving?
    • Is your brake fluid low? Does it appear very dirty?
    • Do you hear a grinding sound or a squealing sound when you apply the brake pedal?
    • Do you feel a pulsation or some sponginess in the brake pedal when it is depressed?
    • Does your vehicle steer or pull to one side when braking?
  • When do I need radiator service?

    Cooling system failure is the number one cause of vehicle breakdowns. Because there are often no visible warning signs of deterioration, radiator and cooling system maintenance service is frequently overlooked by vehicle owners.

    Your engine is constantly burning fuel and therefore gets very hot. In fact, the temperatures inside the combustion chamber may reach 4,500°. It is the job of the cooling system to carry this potentially harmful heat away from the engine to the outside air. To do this, a coolant mixture of water and antifreeze is circulated through the engine block. The coolant absorbs heat from the engine and is pumped by the water pump through hoses to the radiator. Once the radiator transfers the heat from the engine to the outside air, the coolant circulates back to the engine and the cycle begins again.
