Vehicle Tips

According to recent studies, 5 percent of all motor vehicle fatalities are clearly caused by automobile maintenance neglect.
Vehicle Tips

The cooling system should be completely flushed and refilled about every 24 months. The level, condition, and concentration of coolant should be checked. (A 50/50 mix of anti-freeze and water is usually recommended.)
Vehicle Tips

Never remove the radiator cap until the engine has thoroughly cooled. The tightness and condition of drive belts, clamps and hoses should be checked by a pro.
Vehicle Tips

Change your oil and oil filter as specified in your manual, or more often (every 3,000 miles) if you make frequent short jaunts, extended trips with lots of luggage or tow a trailer.
Vehicle Tips

Replace other filters (air, fuel, PCV, etc.) as recommended, or more often in dusty conditions. Get engine drivability problems (hard stops, rough idling, stalling, diminished power, etc.) corrected at a good shop.
Vehicle Tips

A dirty windshield causes eye fatigue and can pose a safety hazard. Replace worn blades and get plenty of windshield washer solvent.
Vehicle Tips

Have your tires rotated about every 5,000 miles. Check tire pressures once a month; let the tires cool down first. Don't forget your spare and be sure your jack is in good condition.
Vehicle Tips

Check your owner's manual to find out what fuel octane rating your car's engine needs then buy it.
Vehicle Tips

Keep your tires inflated to the proper levels. Under-inflated tires make it harder for your car to move down the road, which means your engine uses more fuel to maintain speed.
Vehicle Tips

Lighten the load. Heavier vehicles use more fuel, so clean out unnecessary weight in the passenger compartment or trunk before you hit the road.
Vehicle Tips

Use the A/C sparingly. The air conditioner puts extra load on the engine forcing more fuel to be used.
Vehicle Tips

Keep your windows closed. Wide-open windows, especially at highway speeds, increase aerodynamic drag and the result is up to a 10% decrease in fuel economy.
Vehicle Tips

Avoid long idling. If you anticipate being stopped for more than one minute, shut off the car. Contrary to popular belief, restarting the car uses less fuel than letting it idle.
Vehicle Tips

Stay within posted speed limits. The faster you drive, the more fuel you use. For example, driving at 65 miles per hour (mph) rather than 55 mph, increases fuel consumption by 20 percent.
Vehicle Tips

Use cruise control. Using cruise control on highway trips can help you maintain a constant speed and, in most cases, reduce your fuel consumption.
Vehicle Tips

Keep your engine tuned. A fouled spark plug or plugged/restricted fuel injector can reduce fuel efficiency as much as 30 percent.
Vehicle Tips

Inspect the engine's belts regularly. Look for cracks or missing sections or segments. Worn belts will affect the engine performance.
Vehicle Tips

Have the fuel filter changed every 10,000 miles to prevent rust, dirt and other impurities from entering the fuel system.
Vehicle Tips

Change the transmission fluid and filter every 15,000 to 18,000 miles. This will protect the precision-crafted components of the transmission/transaxle.
Vehicle Tips

Inspect the suspension system regularly. This will extend the life of the vehicle's tires.

What our clients say about us?

Reviews and comments from our satisfied customers

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.

Sonia H.
Wonderful service. We have had several of family cars repaired at Greg's. Trust and fast service.

Wilma S.
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.

David P.
People there are extremely nice! When I walk in or call them you instantly feel like a friend that you've known for a few years. That's how well they treat you, you never feel like just a business opportunity it's more of friendship. Highly recommend you go to them for service if you ever need it.

Corey H.
I came to know Greg when he was working for another shop. Loved his attitude from that day. Asked for him a few months later, but found that he had opened his own shop. I have had work done on my cars by this new shop for many years now, mostly on stuff too hard to do on my own. And he is honest, stands behind his work, reasonable price, friendly and punctual. He keeps you up to date, and there are no surprises sprung upon you. And I know of others who are his repeat customers for those very reasons. I do not typically go around recommending businesses, but for this one, I will do so. Take your car to him, and I am sure you will be happy. Everybody needs to know a good, honest mechanic.
