How often do I really need an oil change?
The recommended frequency for oil changes can vary, but most experts suggest changing your engine oil every 5,000 to 7,500 miles, or every 6 to 12 months. However, the exact interval can depend on factors like your driving habits, vehicle type, and oil quality.
Understanding the Need for Regular Oil Changes
Engine oil plays a crucial role in keeping your vehicle running smoothly. It lubricates the moving parts, reduces friction, and helps prevent wear and tear on the engine. Over time, the oil breaks down and becomes less effective, which can lead to increased engine wear and decreased fuel efficiency.
Regularly changing your oil is one of the most important maintenance tasks for your vehicle. Neglecting oil changes can result in serious and costly engine problems down the road.
Factors That Affect Oil Change Frequency
While the general recommendation is to change your oil every 5,000 to 7,500 miles, there are several factors that can influence the optimal oil change interval for your vehicle:
- Driving Conditions: If you frequently drive in stop-and-go traffic, tow heavy loads, or operate your vehicle in extreme temperatures, you may need to change your oil more often.
- Oil Type: Synthetic oils generally last longer than conventional oils, so you may be able to extend the interval between changes if you use a high-quality synthetic oil.
- Vehicle Age and Mileage: Older vehicles or those with higher mileage may require more frequent oil changes to ensure optimal engine performance and longevity.
- Manufacturer Recommendations: Always refer to your vehicle's owner's manual for the manufacturer's recommended oil change interval, as this may differ from the general guidelines.
By considering these factors and following the manufacturer's recommendations, you can ensure that your vehicle's engine is properly maintained and running at its best.

How often are oil changes actually needed?
between 5,000 and 10,000 miles
Most modern vehicles recommend oil changes between 5,000 and 10,000 miles, with many falling in the 7,500-mile sweet spot. Luxury vehicles often have longer intervals; for example, many BMW and Mercedes models can go 10,000 miles between changes.
Is $100 for an oil change normal?
An oil change costing $100 is not standard but can be justified depending on the vehicle and oil type. A basic conventional oil change typically costs between $35 and $75, but a full synthetic oil change can easily fall in the $65 to $125 range. The price will also vary based on location, the specific vehicle's needs, and any additional services included.
Factors that influence the cost
- Type of oil: Conventional oil is the cheapest option, followed by synthetic blends, and then full synthetic oil, which is the most expensive but lasts longer.
- Vehicle type: Some cars require more oil, specific filters, or specialized synthetic oils (like those for European cars), which can increase the price.
- Labor costs: Labor rates vary by location, and modern vehicles may have more complex engines or larger oil pans that increase the complexity and time of the job.
- Additional services: Many service centers offer add-ons like tire rotations, fluid top-offs, or inspections, which will increase the total cost.
How to determine if $100 is reasonable
- For a full synthetic oil change: If you drive a vehicle that requires full synthetic oil, a price of $100 is within a normal range, especially at a dealership or for a premium service package.
- For a conventional oil change: A $100 price for a conventional oil change is likely too high and may be a sign of upselling for additional, unnecessary services.
- Compare quotes: It is always a good idea to compare prices from different service centers to ensure you are getting a fair price for the service your car needs.
Can you go 2 years without changing oil?
No, you should not go two years without changing your car's oil, as it can cause serious engine damage. Even if you drive very little, oil breaks down over time and collects contaminants, and most manufacturers recommend changing the oil at least once a year, or at the very latest, every 15,000 miles for newer cars with synthetic oil. You should always consult your car's owner's manual for the specific recommendation for your vehicle, as factors like driving habits, vehicle age, and oil type can affect the required frequency.
Why you should not skip oil changes
- Oil degrades over time: Engine oil doesn't just get dirty from use; it also breaks down chemically over time, especially when exposed to air and moisture, which can lead to the formation of sludge and a loss of lubricating properties.
- Contaminants build up: Over time, the oil will trap dirt, metal particles, and other debris from the engine. A two-year interval allows these contaminants to build up to levels that can cause significant wear on engine components.
- Reduced lubrication: As the oil degrades, it can become thinner or thicker, reducing its ability to properly lubricate and cool the engine's moving parts. This can lead to increased friction, overheating, and eventual engine failure.
What to do instead
- Check your owner's manual: This is the most crucial step, as the manufacturer provides the definitive service schedule for your specific make and model.
- Use the time-based interval: Most modern vehicles recommend an oil change at least every 12 months, regardless of mileage.
- Change your oil and filter regularly: The most reliable way to protect your engine is to follow the manufacturer's recommendation for both mileage and time, and always replace the oil filter when you change the oil.
Do time intervals with oil really matter?
Time is a factor: Even for vehicles with low mileage, oil degrades over time due to oxidation and condensation. Most manufacturers recommend changing oil at least once a year, regardless of miles driven.
