Oil Filter FAQs
How often should oil filters be changed?
Consult your owner's manual to determine the maintenance interval for your vehicle's oil filter. Some manufacturers recommend that the oil filter be replaced every time you get your oil changed while others recommend every other time.
Why is water leaking on my foot on the driver's side?
The most common cause is a blocked air conditioning drain hose. This is a simple repair at Greg's Auto Service and Repair. There are other possible causes of water dripping on your foot on the driver's side of the car including a broken door seal or leaking heat exchanger.
Why is my car leaking a sweet-smelling fluid?
If there is a sweet-smelling fluid leaking from your car, the most likely culprit is leaking coolant or antifreeze. A coolant leak can become a serious problem. If your vehicle gets too low on coolant or antifreeze, it will overheat and may cause engine damage.
FAQs About Automobile Squeaks, Squeals and Rattles
Why are my wheels making a chirping sound when I accelerate?
The most common reason why your car's wheels make a chirping or squealing sound, especially during acceleration is a bad wheel bearing. If you notice a grinding or grating noise coming from your wheel this can also be the sound of a wheel bearing beginning to fail. If you are in St. Louis, St. Charles, Maplewood, Clayton or the surrounding area, come by Greg's Auto Service and Repair and we can diagnose the problem quickly.
Why does my car make a noise when I turn the steering wheel?
If your car makes strange sounds or clicks when you turn the steering wheel the most common cause is a low steering fluid. Over time the steering fluid decreases and air enters the steering mechanism causing unwanted noises. Come to Greg's Auto Service and Repair to top off your fluid reservoir with power steering fluid. The noises should start to go away immediately. If the sound returns quickly your car could be leaking steering fluid. Our professionals in St. Louis can help you diagnose and repair leaks quickly and affordably.
Why is my car making a squealing noise?
It may be a slipping fan belt. Listen for a few warning signs such as a squeaking or chirping noise. Those noises are usually caused by misalignment of the belt and the pulley. If you come by Greg's Auto Service and Repair in St. Louis our professional auto repair technicians can realign it to stop the noise and fix it before your fan belt completely breaks.

What Our Customers Are Saying
I'm a 28-year-old female professional, who has spent many years as an extremely WARY customer of auto shops. This sense of distrust was a result of a myriad of bad experiences with mechanics who took advantage of my lack of knowledge for cars. HOWEVER, I would HIGHLY RECOMMEND putting your faith in Greg's Auto Service and Repair. This is a remarkably well-run business, operated by an owner who actually cares about his customers - not an ounce of greed in this man's heart. My car was in dire need of good attention, and that's exactly what it got. I'm so thankful I stumbled across his business, and I wouldn't take my car anywhere else after working with Greg and his wife Marsha. What a team! This is a MUST-GO repair shop.

I've never met a more honest repair shop. They are fantastic. Fast. Reasonable and they don't try to sell me something I don't need. My friends turn me on to Greg's and I'm really happy they did. If you want to feel safe, looking for a mechanic, then I recommend Greg's Auto.
