Do I really need to change synthetic oil every 6 months?
As a car owner, you may have heard various recommendations regarding oil changes, particularly when it comes to synthetic oil. With years of experience in car maintenance and repair at Kevin's Autos, I want to clarify the necessity of changing synthetic oil every six months and provide you with the insights you need to make informed decisions about your vehicle's maintenance.
Understanding Synthetic Oil
Synthetic oil is engineered to provide superior performance compared to conventional oil. It offers better protection against engine wear, improved fuel efficiency, and enhanced performance in extreme temperatures. However, the question remains: how often should you change it?
Factors Influencing Oil Change Frequency
While the traditional guideline suggests changing synthetic oil every six months, several factors can influence this recommendation:
- Driving Conditions: If you frequently drive in stop-and-go traffic, extreme temperatures, or on short trips, your oil may degrade faster.
- Vehicle Type: Some vehicles, especially high-performance models, may require more frequent oil changes due to their engine design and usage.
- Manufacturer Recommendations: Always refer to your vehicle's owner manual for specific oil change intervals, as manufacturers often provide tailored guidelines based on extensive testing.
- Oil Quality: The quality of synthetic oil can vary. Higher-quality oils may last longer and provide better protection, potentially extending the time between changes.
General Recommendations
In general, many modern vehicles can go longer than six months between synthetic oil changes. Some manufacturers recommend intervals of up to 7,500 to 10,000 miles, depending on the factors mentioned above. However, it's crucial to monitor your oil level and condition regularly.
Conclusion
While changing synthetic oil every six months may be a good rule of thumb for some drivers, it's essential to consider your specific driving habits and vehicle requirements. Regular maintenance checks and staying informed about your vehicle's needs will help ensure optimal performance and longevity. If you're ever in doubt, don't hesitate to consult with a trusted mechanic at Kevin's Autos for personalized advice.
Frequently Asked Questions
Does synthetic engine oil have a shelf life?
Answer. ExxonMobil recommends a five-year maximum shelf life for engine oils, including Mobil 1™ synthetic motor oil.
What happens if I go 6 months without an oil change?
When your oil isn't changed regularly the pistons will start to cut into the piston chamber creating metal shavings. The metal shavings will start to spread into the other chambers causing more damage ultimately ceasing the entire engine.
Does full synthetic oil need to be changed every 6 months?
“While synthetic generally holds up better and can serve for more miles, it is equally important to not extend oil changes beyond the time interval recommended by the manufacturer, typically six months or a year if it is a motor that is not driven many miles or on many short trips.”
Does oil really go bad after 6 months?
Yes. It should be changed no later than 6 months or after the amount of miles the manufacturer recommends, whichever comes first. Unopened it can last up to 5 years. At some point, the additives that help keep the engine clean and prevent oxidation (rust) of the metals begin to separate from the oil.
What's the longest I can go without an oil change?
5,000 to 7,500 miles
It used to be that an oil change was needed every 3,000 miles. However, engine technology has improved greatly over the years. Due to this, cars can generally go 5,000 to 7,500 miles before needing an oil change.
Can you go 10,000 miles with synthetic oil?
In general, though, modern cars can manage 5,000 to 7,500 miles between oil changes. If your vehicle calls for a blended or full synthetic oil, you can push that to 10,000 miles.
How often should you change fully synthetic engine oil?
The duration a car can run on full synthetic oil without an oil change can vary based on several factors, including the manufacturer's recommendations, driving conditions, and the type of engine. Generally, full synthetic oil can last between 7500 to 15000 miles (approximately 6 to 12 months) before needing a change.
Is it necessary to service a car every 6 months?
However, if you don't put many miles on your car, most automakers recommend an oil change service every 12 months, even if the maintenance reminder hasn't come on. Older cars have service intervals based on mileage.
How long will synthetic oil last in a stored car?
Even in a car that's rarely driven, oil doesn't enjoy an infinite lifespan. The rule of thumb is about six months—despite oil's typical shelf life of five years.
Is it bad to change synthetic oil too often?
If you're changing your oil more frequently than necessary, it won't help your car. It doesn't harm it either, but you're wasting money, time and resources. Keep in mind, too, that throwing away oil that's still usable puts a strain on the environment.
