    Precision had to order a tire to replace one damaged by a nail in the sidewall. It arrived in a timely manner and was able to be installed on Thursday. I also had my air and cabin filter replaced. I arrived 45 min. early for my appt. and they were able to do the work right away. I appreciate their service and flexibility!

    I've been going to Precision Auto for a long time now. I know the owner personally and he is one of the best mechanics I've worked with. Personally I've been in the automotive industry for almost 14 years now and I've seen my fair share of good and bad mechanics. Aaron the owner is a top notch mechanic and an even better human. He's honest and fair and his team provides good quality service. TJ is the guy you will see when you walk in. He runs the show from answering the phone to setting appointments. Don't let his administrative skills fool you he can definitely wrench on a car. They work on pretty much anything. I've taken my American cars there and our German cars as well. We take our 2016 Mercedes there for oil changes and they did brakes on it as well. They are well versed on all makes and models. I highly recommend the boys at Precision. I can't say enough good things about my experiences with cars there. They also do emission tests there as well. Stop and see them. BONUS INFO: THEY HAVE A PULL TAB MACHINE!!!! Go and try to win at cardboard crack!!! If you win I get 25% of your winnings🤣

Frequently Asked Questions About Precision Auto & Diesel

Should I keep an eye on fluids and filters?

Your car’s engine is full of sensitive and delicate moving parts that rely on fluids like oil, transmission fluid, and coolant to function well. If you don’t keep an eye on these fluid levels or periodically change the filters, these delicate parts could face irreparable damage. Your car’s brakes also require brake fluid to transfer the force to the brakes to slow or stop your vehicle. It's possible for brake fluid to lose its effectiveness or for leaks to occur. If you experience abnormal brake performance, make sure to have your car checked. Coolant or antifreeze prevents overheating and freezing of the engine's cooling system. Like brake fluid, recommended service intervals vary by manufacturer and can range from roughly a few years to a recommended check during every scheduled maintenance service. Keep an eye on your coolant level to ensure there aren't any leaks. If you ever see the engine temperature warning light turn on, there might be something wrong with your coolant or the amount of coolant remaining.

When should I have my automotive parts replaced?

Your vehicle’s brakes should be examined at least once a year to identify any wear and tear and need for repair. Brake pads and rotors typically last anywhere from 35,000 to 60,000 miles, depending on how often you stop while driving and how thin or thick the rotors and pads are initially. Your car’s battery typically lasts 4 or 5 years, depending on outdoor temperature, driving frequency, and overall use – among other influences. To maximize battery life, keep your battery clean; don't leave your car unused for an extended period, and don't forget to shut off the interior lights and headlights when your car isn't in use. Driving with bad headlights can be very dangerous. Restoring your headlights can have it looking like new and can shine up to 3 or 4 times lighter when driving. You can slow oxidation caused by heat, sunlight, pollution, and harsh chemicals by parking in a garage when possible.
