Diamond Certified Researched Articles on A-1 Performance Auto Repair

researched article

An A1 Performance Auto Repair technician works on a customer’s car.

A1 Performance Auto Repair is a Sunnyvale-based general repair shop that specializes in emissions work (smog testing, certification and smog-related repairs), computer diagnostics and electronics systems. The company’s services range from engine and transmission work to brakes, power steering and fuel injection systems. It also does minor mechanical work, oil changes, routine maintenance, and front and back end repairs (excluding front end alignments).

Cliff Do established A1 Performance Auto Repair in 2000. Mr. Do has many years of experience as an auto mechanic, and he says he’s proud to be at the helm of an entirely family-owned and operated business. He stays aware of industry trends and continually educates himself to remain current with new technological advancements.

A1 Performance Auto Repair services all vehicle makes and models, and it only uses original equipment replacement parts, which, along with labor, are backed by a 12-month/12,000-mile guarantee.

“We consider all our customers to be part of our extended family, and we treat them as such. Because of that, they've remained very happy with our service over the years. They continue to bring their cars to us, and they recommend us to their families and friends. That's the best advertising a business can ask for.”

Follow basic maintenance tips to help keep your car on the road and out of the repair shop.
Auto repairs are sometimes inevitable, but by consistently taking care of your car’s most basic parts and systems, you can often avoid common wear-and-tear problems. Consider the following tips for effectively maintaining your vehicle:

Tires
A car tire inflated to 35 pounds per square inch (psi) can lose one psi every month or for every temperature change of 10 degrees Fahrenheit. Find the recommended psi level in your owner’s manual or on a sticker on the driver’s side door jamb. Rotate tires every 6,000 miles to prevent uneven wear and have the alignment checked if the car pulls to either side while driving.

Engine oil
Follow your vehicle’s manufacturer guidelines to determine how often you should change the oil—typically, it’s every 3,000 to 4,000 miles, or three to six months. Cliff Do, owner of A1 Performance Auto Repair in Sunnyvale, says this rule varies with the type of oil your car requires. “With the new synthetic oils, you can go 7,000 to 10,000 miles between changes. Either way, make sure you don’t go too long without an oil change, because you risk damaging your car.”

To check your car’s oil level, park on a level surface and turn the engine off. Open the hood, remove the dipstick, wipe it clean with a cloth or paper towel and return it to the oil reservoir. Remove it again to see if the oil level is within the acceptable range marked on the dipstick. If you have to add oil, make sure you don’t overfill—too much oil can damage the engine.

Transmission fluid
Look for a reservoir marked ATF (automatic transmission fluid) and follow the same steps as monitoring the oil level—only this time, keep the engine running. You should change transmission fluid every 30,000 miles or so, but follow the manufacturer’s recommendations to be certain.

Engine coolant
Most engine coolant or antifreeze should be replaced every 30,000 miles (two to three years). Newer formulas, however, can last up to 50,000 miles. To check the coolant level, turn the car off and wait for the engine to cool. Locate the coolant reservoir (usually a translucent plastic tank) and check the level of the coolant against the full and low indicators.

Power steering fluid
Power steering fluid should be changed every three years or 50,000 miles. If your car has a power steering fluid reservoir, check the level visually; otherwise, follow the dipstick method. Low power steering fluid may indicate a leak, so have your mechanic take a look.

Air filter
Change your air filter every 12,000 to 15,000 miles. A clean air filter can improve gas mileage and reduce harmful emissions.

Fuel filter
Replace the fuel filter every year to help prevent debris from clogging your car’s fuel line.

Windshield wipers and wiper fluid
Windshield wiper care is one of the most neglected basic car care tips. Replace the wiper blades every six to 12 months or whenever the rubber becomes worn. Check the wiper fluid reservoir every week or so and keep it full.

Headlights and brake lights

With your car turned on and parked, have someone walk around to confirm all your lights are working—headlights, brake and tail lights, turn signals, etc. Replacing bulbs in modern vehicles can be a challenge, so consider having a mechanic do the job (especially replacing and aiming headlights). A mechanic will also know the difference between a blown fuse and a burned out bulb.

Maintaining customer satisfaction is a crucial aspect of any business, but it's even more important for auto repair companies that have earned the prestigious Diamond Certified award. For A1 Performance Auto Repair, preserving a high level of customer satisfaction is dependent upon treating each person who comes to its Sunnyvale shop like family–a personalized business approach that's endeared the company to its clientele base. "I believe our attitude is the reason we've been so successful," says owner Cliff Do. "Almost all our business comes from repeat customers. If they come in once, our quality service ensures they'll come in a second time and refer us to others."

A1 Performance Auto Repair provides routine maintenance services and repairs for all types of domestic, European and Japanese vehicles. In addition to working on engines, transmissions and electrical systems, the company handles diagnostics, smog testing and repairs, oil changes and more. "Unlike some of our competitors, we believe in doing the job right the first time and giving detailed explanations of our work," says Mr. Do. "For example, if we have to replace a part, we keep the old one, show it to the customer and explain why it had to be replaced."

One of the most distinguishing features of A1 Performance Auto Repair is the vast amounts of industry experience and education possessed by Mr. Do and his employees. "I'm an ASE Master Technician, and all our technicians are ASE-certified, which means they've undergone rigorous training and testing on the latest industry trends and equipment," he says. "Our customers can feel confident that their cars are being serviced by skilled, qualified technicians."

Cliff Do: A Dynamic Development

By James Florence, Diamond Certified Resource Reporter

SUNNYVALE – Cliff Do’s career as an auto repair professional started small, but it developed gradually as he worked his way up from the basics to the big leagues. “I’ve loved auto repair since I was a kid,” he says. “As a teenager, I worked on motorcycles and scooter bikes, and from there I moved to diesel and gasoline engines. I was never satisfied doing just one thing; rather, I wanted to learn how to work on all types of cars, from dom...
