They didn't just recommend services--they explained why each one mattered. Services performed: - Oil Change - The foundation of engine health. Keeps everything lubricated and running smooth. - Front & Rear Differential Service - Crucial for vehicles with AWD or 4WD. This keeps your wheels turning properly and prevents wear in the gears that transfer power from the engine. - Automatic Transmission Service - Ensures smooth shifting and protects against costly transmission failure. - Fuel Treatment - Cleans out the fuel system, improves mileage, and helps the engine run cleaner and stronger. Selena was fantastic--friendly, knowledgeable, and efficient. David backed it up with solid mechanical insight. Together, they made sure I understood what my vehicle needed and why. Hours that actually work for real people: - Monday-Friday: Open until 6pm - Saturday: Open until 5pm - Sunday: Open until 4pm When no one else was open, they were. That alone makes them a gem. They've taken over some of the old oil change shops in town and brought real service back to the area. All of this came out to around half a grand, which is a great price considering the scope of work and the long-term protection it gives my engine. I'm confident driving cross-country now, and I'll definitely be back. --- Want me to tailor this for Yelp or Google, or add a punchier headline?

The tech showed me the crack and then, after going inside they used their price sheet in their computer to give me a price for the repair based on the make and model of my vehicle, the replacement parts and the time it would take for the repair. Estimated time was three hours and they said they'd have it all done before the end of the day. (It was after 11 am at the time.) I got a call around 4 pm that the car was done. Nice. Great. They treated me well and I felt they were honest with me about everything and finished the work well before the end of the day. I'd definitely recommend taking your car here to be repaired.

There is a reason why there is a full line and a low line on the oil stick. But they will lie to your face. Both locations over the years have done shady business. Don't get ripped off or told somethings wrong or need to be changed out on your vehicle. This place will rob you and take your money while sleeping good at night. No integrity at both locations.

Grease Monkey opened at 8am and I called right at opening. At arrival all employees were very friendly and very informative. They didn't charge me to diagnose the issue and would only charge me on repairs. Matt was amazing and took the time to point out a few things and asked me to drive the car around for a while and bring it back to make sure everything was good. I will definitely be coming here if needed when I visit my daughter at Utah Tech. I'm also bringing her car and recommending them to her follow students. I couldn't have had a better experience at a mechanic shop.

I want to give a huge shoutout to Ryan from R&J Mobile Mechanics. I was in Zion for a few days…read morewhen, unfortunately, my battery light came on. The next morning I drove about 30 minutes down the mountain to AutoZone to have the battery tested. It turned out the battery wasn't holding a charge, and I was told the next thing to check would most likely be the alternator. I called multiple mechanics and mobile mechanics in the area until my brother found Ryan. At first, there wasn't much he could do because we had to emergency order an alternator from Vegas. I was able to get a warranty replacement battery from AutoZone and continue my plans for the day. The following evening around 5:30 PM, Ryan came out and was able to take care of the repair. He even helped order the correct alternator through AutoZone for me. He showed up on time, checked every possible option, and took the time to properly troubleshoot the issue instead of just guessing. After testing everything, we determined the alternator was the most likely problem. The installation only took him about 40 minutes. Afterward, we tested everything multiple times using different meters and code readers, took the vehicle for a test drive, and made sure everything was working correctly. I was nervous at first because there was still a strange noise after the repair, but Ryan took the time to troubleshoot it further until everything checked out. The battery light was gone, all tests passed, and I was able to safely drive over 350 miles back to California without any issues. I really appreciate Ryan's professionalism, honesty, and willingness to help while I was stranded away from home. If you're ever in the Zion area and need a reliable mechanic, I highly recommend R&J Mobile Mechanics.
