Consequences of Delaying Oil Changes
Reduced Engine Performance and Inefficiency
What happens if you disregard an oil change? Delaying this car service can lead to several consequences, including:
- Reduced engine performance – without fresh oil, your engine won’t have enough lubrication, causing contaminants to damage components.
- Inefficient gas mileage – fresh oil provides lubrication that allows the engine to run efficiently without consuming excessive gasoline.
- Overheated engine – oil helps keep the engine cool by passing through a cooler.
Increased Costs and Engine Wear
Using oil for too long, or through dirtier conditions means it needs changing more frequently. Motor oil changes are crucial to keep the engine clean, to run efficiently, and to reduce metal wear. When oil deteriorates, it can gel, solidify and form sludge, leading to a buildup of debris and loss of lubricating properties, increasing the rate of engine and component abrasion.
Oil Change Intervals
Cars can typically go 5,000 to 7,500 miles before an oil change is necessary. With synthetic oil, you might be able to go 10,000 or even 15,000 miles between changes. Always check your vehicle’s manual for manufacturer recommendations.
Understanding Oil Change Frequency
Typical Mileage for Oil Changes
- Cars can usually go 5,000 to 7,500 miles between oil changes.
- With synthetic oil, we can extend that range to 10,000 or even 15,000 miles.
Dangers of Overdue Oil Changes
- Engines may overheat and wear excessively.
- Debris may damage engine parts, or sludgy oil may cause the engine to fail.
Oil Longevity
- With modern lubricants, recommended intervals are 5,000 to 7,500 miles.
- Full-synthetic motor oils might extend that up to 15,000 miles between services.
Can Oil Last 2 Years?
- The shelf life of conventional motor oil is up to five years under optimal conditions.
- It is generally not recommended to go 2 years without an oil change due to the risk of oil breakdown and engine damage.
When to Change Oil: Mileage vs. Time
Mileage Guidelines
- The average oil change interval is around 3,000-5,000 miles, depending on oil type and driving conditions.
- Some vehicles can go further, up to 7,500-10,000 miles, but always consult your manual.
Yearly Changes and Engine Health
- Manufacturers typically recommend yearly oil changes for driving 6,000 miles or less.
- For those driving greater distances, up to 15,000 km (about 10,000 miles), an annual check is advisable.
- Keep in mind that factors such as oil type and driving conditions may affect these intervals.
General Recommendations
- While advanced vehicle systems may extend intervals, two years without an oil change is typically too long.
- Err on the side of caution and change oil earlier than later to minimize engine damage risk.
Why Regular Oil Changes are Essential
Lifespan of Motor Oil
- Most motor oils will be effective for about 5,000 miles before replacement is needed.
- Engine oils do expire and it’s best not to extend beyond 2-5 years to avoid engine harm.
Prevention and Maintenance
An ounce of prevention is worth a pound of cure. Regular oil changes are crucial for keeping your car in top condition. Check your vehicle’s manual for specific oil change needs, as they can vary based on different factors.
