Normal vehicle usage causes various parts of your engine to lose their efficiency because of under-the-hood temperature and vibration.
Tuning a car up in today’s technologically sophisticated world is a different process. The exact methods will vary by make and model of your car, but common steps taken include:
- Changing the air and fuel filters to improve the car efficiency
- Replacing spark plug electrodes as they wear down
- Cleaning and decarbonizing the throttle body and fuel system. Oil vapors from the positive crankcase ventilation system lead to carbon build up.
The Import Master will also check fluid levels, inspect the engine elements and make minor adjustments necessary to improve performance. Since computers are such a large part of the functioning of the vehicle, often there are no adjustments to make.
In addition to performing a tune-up, keeping tires properly inflated improves gas mileage by 3 percent. A clean air filter can improve fuel efficiency by as much as 14 percent on older vehicles and also helps the environment, as do regular oil and oil filter changes. Air filters are usually inspected during an oil change, which should be performed regularly as recommended in the owner’s manual. Tire pressure should be checked monthly.
For most models, it is the number of miles driven that matter. On average, tuning is done every 30,000 miles – in other words, at the 30,000 mile mark, the 60,000 and again at 90,000 miles. Some models need it done more frequently, some less often. The owner’s manual will give specifics on when different types of maintenance are due.
It’s a good idea to consider a tune up before you take a road trip, and maybe even after, depending on how many miles you put on your vehicle.
