Can I still drive my car if it says oil change required?
Yes, you can still drive your car if the oil change indicator light is on, but it's important to get the oil changed as soon as possible. Ignoring the oil change light can lead to serious engine damage over time.
Understanding the Oil Change Indicator Light
The oil change indicator light, also known as the maintenance required light or change oil light, is a warning signal that your car's onboard computer system uses to alert you that it's time for an oil change. This light typically turns on after a certain number of miles or hours of engine operation, indicating that the oil has degraded and needs to be replaced.
Driving with the oil change light on is generally safe in the short term, as long as you get the oil changed within the next few hundred miles or so. However, continuing to drive with old, dirty oil can lead to increased wear and tear on your engine's components, potentially causing more serious problems down the road.
Potential Consequences of Ignoring the Oil Change Light
- Increased engine wear: Old, dirty oil loses its lubricating properties, which can cause increased friction and wear on engine parts like the pistons, bearings, and crankshaft.
- Reduced fuel efficiency: Dirty oil can reduce your car's fuel efficiency, leading to higher fuel costs and increased emissions.
- Engine damage: In extreme cases, neglecting an oil change can lead to engine seizure or failure, which can be an expensive repair.
It's important to note that the specific mileage or time interval for an oil change can vary depending on your car's make, model, and driving conditions. Consult your owner's manual or speak with a trusted mechanic to determine the recommended oil change schedule for your vehicle.
Tips for Maintaining Your Car's Oil
- Check the oil level regularly: Make a habit of checking your car's oil level at least once a month, and top it up if necessary.
- Change the oil on time: Follow the manufacturer's recommended oil change interval, which is typically every 5,000 to 10,000 miles or every 6 to 12 months.
- Use the right oil type: Check your owner's manual to ensure you're using the correct oil type and viscosity for your car.
- Consider synthetic oil: Synthetic oils can provide better protection and longer service intervals than conventional oils.
By staying on top of your car's oil maintenance, you can help extend the life of your engine and avoid costly repairs down the line.
What happens if a car says oil change is required?
It signals that your car's engine oil needs replacement, which many of us tend to postpone. But what happens if you don't get your oil changed? The answer is simple yet startling — engine damage, reduced performance and potentially expensive repairs.
Can you drive with the oil change warning?
No, you should not drive with the oil change or low oil pressure light on, as it can cause severe engine damage and lead to costly repairs. The light indicates a problem with oil pressure, and continuing to drive can cause friction, heat, and potential engine failure. Pull over immediately, turn off the engine, check the oil level with the dipstick, and add oil if it's low. If the problem persists or the light is for low pressure, have the car professionally inspected.
What to do immediately
- Pull over and stop: As soon as it is safe, pull to the side of the road and turn off the engine.
- Check the oil level: Wait a few minutes for the oil to settle, then use the dipstick to check the oil level.
- Add oil if needed: If the level is low, add oil. If you don't have any, you should call for a tow, as driving without sufficient oil is very dangerous.
- Do not ignore it: If the light is for low oil pressure, it indicates a serious issue that needs to be addressed by a mechanic right away.
Dangers of ignoring the light
- Engine damage: Low oil pressure means the engine's moving parts are not getting enough lubrication, which can cause them to grind against each other, leading to severe internal damage.
- Engine failure: Driving with low oil can cause the engine to seize, leading to a complete breakdown.
- Voided warranty: Driving with the oil light on can void your car's warranty, meaning you would be responsible for all repair costs.
Is it okay to drive when a car needs an oil change?
Driving a short distance past the scheduled oil change is usually low-risk, especially with modern synthetics; repeatedly ignoring intervals or driving far past them increases wear, triggers deposit formation, and can lead to expensive engine damage.
How long can you drive on an oil change required?
You should change your oil as soon as possible after the "oil change required" light comes on, ideally within a few hundred miles, but driving a little longer is unlikely to cause immediate damage if you're not experiencing other symptoms. It is best to avoid driving for extended periods, especially if you have to drive long distances or in severe conditions.
What to do
- Check your owner's manual: This will provide the manufacturer's recommended interval, which is the most reliable source.
- Monitor oil level: If the light comes on, check your oil level and add oil if it's low.
- Schedule an appointment: Book an oil change at your earliest convenience.
- Note the time/mileage: Be sure to get the oil changed before the recommended interval is exceeded in the future.
Risks of delaying an oil change
- Accelerated engine wear: Oil lubricates and cools engine parts. Old, dirty oil can't lubricate properly, leading to increased friction and wear.
- Overheating: The engine may run hotter due to increased friction.
- Sludge buildup: Old oil can turn into a thick sludge that clogs oil passages and causes major engine problems.
- Corrosion: Old oil can contribute to the corrosion of engine parts.
- Oil leaks: In severe cases, the increased pressure and heat can lead to oil leaks.
