Signs You Need the Service
Modern cars often have monitors, but physical signs still matter. If you are unsure when your last car oil change was, watch for these warnings that your oil is struggling to protect your vehicle and maintain fuel efficiency.
- Dark or Gritty Oil: Fresh oil is amber; black, textured oil is saturated with contaminants.
- Engine Noise: Knocking or ticking sounds indicate a lack of proper lubrication.
- Exhaust Smoke: Blue or gray smoke suggests oil is burning inside the engine.
- Oil Smell: A burnt oil scent inside the cabin usually points to a leak dripping on hot engine parts.
Frequently Asked Questions
What type of oil should I use for my car?
Your owner’s manual provides the best guidance on the type of oil recommended for your specific vehicle. Our technicians can also help determine whether conventional, synthetic blend, or full synthetic oil is the best choice for you.
Can I extend the time between oil changes if I use synthetic oil?
Yes. Synthetic oil generally lasts longer than conventional oil and can often go between 7,500 and 10,000 miles between changes. However, you should always follow your manufacturer’s guidelines.
What happens if I don’t change my oil regularly?
Over time, old oil breaks down and becomes contaminated, reducing its effectiveness. This can lead to sludge buildup, poor engine performance, reduced fuel efficiency, and even engine failure.
How can I tell if my car needs an oil change?
Common signs include dark, dirty oil on the dipstick, a burning oil smell, decreased fuel efficiency, unusual engine noises, and the oil change or check engine light turning on.
