Signs Your Car Needs Some Care

- Squealing, grinding, knocking or clunking noises
- Fluid spots under the car: oil, coolant or transmission fluid
- The car pulls, vibrates or the steering feels loose
- Rough shifting, hard starts or loss of power
- Warm air from the AC or a burning smell
- Worse fuel economy than usual

How Often Should You Get Auto Maintenance?
Most vehicles benefit from routine maintenance every 5,000–7,500 miles, depending on your manufacturer and how you drive. Stop-and-go traffic on Sunset Boulevard, short trips, towing and Utah’s hot, dry summers and cold winters all count as hard use. Follow your owner’s manual, and use this as a guide for the most common services:
| Service | Typical interval |
|---|---|
| Oil change | 3,000–7,500 miles depending on oil type |
| Tire rotation | Every 5,000–8,000 miles |
| Brake inspection | Every 10,000–15,000 miles or once a year |
| Alignment check | Yearly and with new tires |
| Tune-up | Every 30,000 miles or three years |
| Transmission fluid | Every 30,000–60,000 miles |
| AC check | Every 1–2 years, before summer |
Stop by any time and we’ll put together a maintenance plan for your vehicle.

What Auto Repair Costs at Master AutoTech St. George
We don’t guess at prices. We inspect first, explain what we find and give you an estimate before any work starts, so you approve the cost up front. The check engine light scan is free, and you can request an estimate online. What drives the price is the part that failed, the labor to reach it, your vehicle and the parts grade you choose.
