Questions about Tune-up Service
Troubleshooting Guide
How often should I replace my car’s air filter?
Most manufacturers recommend replacing the engine air filter every 12,000 to 15,000 miles, but this can vary based on driving conditions. If you frequently drive on dusty roads or in heavy traffic, you may need to change it more often to keep your engine breathing clean. Contact Preferred Automotive if you need help checking the concern.
What are the signs my air filter needs to be replaced?
Common signs include reduced fuel efficiency, sluggish acceleration, or a dirty, clogged filter when visually inspected. You might also notice unusual engine sounds or even a check engine light if airflow is severely restricted. Contact Preferred Automotive if you need help checking the concern.
Is there a difference between an engine air filter and a cabin air filter?
Yes. The engine air filter keeps dirt and debris out of your engine, while the cabin air filter cleans the air you breathe inside the car. Both should be checked regularly and replaced as needed. Contact Preferred Automotive if you need help checking the concern.
How often should I change my oil?
Most cars need an oil change every 3,000 to 5,000 miles, or as recommended by your manufacturer. Newer vehicles and synthetics can go longer. Contact Preferred Automotive if you need help checking the concern.
What happens if I delay my oil change?
Old oil loses lubrication properties, which can lead to increased engine wear and costly repairs down the road. Contact Preferred Automotive if you need help checking the concern.
Do I need to change my oil filter every time?
Yes. It’s best to replace the oil filter with each oil change to remove contaminants and keep your new oil clean. Contact Preferred Automotive if you need help checking the concern.
What does preventative maintenance include?
It often covers oil changes, fluid checks, belt and hose inspections, brake checks, and tire rotations — all designed to catch problems early. Contact Preferred Automotive if you need help checking the concern.
How often should I schedule preventative maintenance?
Following your vehicle’s maintenance schedule, usually every 3,000 to 10,000 miles depending on services, helps avoid major issues. Contact Preferred Automotive if you need help checking the concern.
Can preventative maintenance really save money?
Yes. Finding small issues early prevents bigger, more expensive repairs and keeps your car running reliably longer. Contact Preferred Automotive if you need help checking the concern.
What’s included in a car tune-up?
Tune-ups can include replacing spark plugs, inspecting filters, checking ignition and fuel systems, and ensuring your engine runs efficiently. Contact Preferred Automotive if you need help checking the concern.
How do I know if my car needs a tune-up?
If you notice rough idling, reduced fuel economy, difficulty starting, or sluggish acceleration, it might be time for a tune-up. Contact Preferred Automotive if you need help checking the concern.
How often should I get a tune-up?
Most cars need a tune-up every 30,000 to 50,000 miles, but check your manual for exact intervals. Contact Preferred Automotive if you need help checking the concern.
