the computer of the vehicle controls the valve timing, ignition timing and fuel delivery. Malfunctions on a vehicle can be camouflaged by the computer, whose function is to keep the engine running as efficiently as possible for as long as possible. It will signal a Service Engine Soon, or Check Engine Light when it detects a problem. But it will try to compensate for that problem at the same time, so the vehicle will still run fairly decent.
On today’s cars it is best to perform tune-ups based on mileage. The vehicle’s manufacturer has mileage based intervals for replacement of these parts and other maintenance services. These are designed to be performed preventatively so that the parts do not fail prior to replacement. Some common mileage intervals and maintenance.
Recommended is as follows:
Every 3,000 miles:
Replace oil & Oil filter.
Inspect air filter – replace as needed
Check and top off all fluids
Check tire pressure (fill as needed)
Every 7,500 miles:
Replace wiper blades.
Every 15,000 miles:
Replace fuel filter & Replace cabin air filter.
Every 30,000 miles:
Replace automatic transmission fluid
Replace automatic transmission filter
Flush cooling system
Replace pcv valve (recommend whenever spark plug replacement interval is)
Replace spark plugs (vehicles with non platinum spark plugs)
Fuel Injection and Carbon Clean Service
Every 50,000 miles:
Replace fluids for:
Every 60,000 miles:
Replace pcv valve
Replace spark plugs (this includes vehicles equipped with platinum spark plugs)
Replace spark plug wires
Replace timing belt (this varies per manufacturers specifications on your vehicle)
The consequences of waiting for parts to fail can be, lack of performance, loss of gas mileage, hard starting issues and etc. For example, if the tune up parts, like the spark plugs get completely worn it can cause the vehicle to misfire and can also cause a hard starting issue. These conditions can cause damage to the exhaust system of the vehicle. If your vehicle has an inline fuel filter it can get plugged over time and can cause fuel pump failure.
So, we recommend following your manufacturer’s specifications on tune-ups and other maintenance, based on mileage intervals. This will help to maintain a new vehicle’s warranty and also add longevity to the life of your vehicle. If you have any questions or comments feel free to contact us at www.peterscreekautomotive.com.
