What is a Tune-Up? And How Do I Know When I Need One?
Most people think of tune-up as changing the spark plugs and wires, but there is often more to it than that. You may need the air filter and fuel filter replaced, adjustments to the valves and/or replacement of the valve-cover gasket, fluids may need topping off if necessary
Even if your car runs fine you should still have a tune-up performed as recommended in your owner’s manual, 12 months/12,000 miles is typical. Not all components of the tune-up will be necessary at every tune-up.
If you’re ever in doubt, check your vehicle manual to learn what maintenance is needed, and when, before you schedule a tune up.
You should also be aware of changes in your car’s normal behavior. Listen carefully; perhaps drive with the radio off so that you can hear engine noises more clearly.
The good news is that barring other major mechanical issues, keeping your car tuned up can dramatically improve performance and it has been shown that replacing your filters may impact the longevity of your vehicle more than any other factor.
Preventative maintenance is a good investment.
