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.

Kudos to Katie! From the call response to in person soft talk. She is just amazing. Went there for an oil change today. Little wait time and job done. The thing that i like more there is no one wasted the time talking nonsense about recommended services like most dealerships and service stations do it these days. I live 18 miles away from them, definitely i am going to have my car for general service and oil changes in future as well.Thank you so much everyone, specially Katie.

This has been my auto shop for about 15 years now. Sully is one of the nicest and most thorough mechanics I have ever met. I fully trust him with all of our car needs. I have to mention how incredibly sweet and super friendly the new office manager Katie is. She guided us through a major car repair and answered all of our questions and was so pleasant along the way! There's not that many trustworthy places left nowadays, you will be in good hands coming here!
