When to Change Your Car’s Oil: A Comprehensive Guide

Anh Tuan, a grocery store owner in Hanoi’s Old Quarter, always took pride in his Dongfeng truck—his reliable partner for five years. Recently, he noticed the engine becoming sluggish and louder than usual. A trip to his trusted mechanic revealed a neglected oil change, a consequence of Tuan’s busy schedule.

Tuan’s story highlights the importance of regular oil changes. But how often should you change your car’s oil? This guide provides essential information.

How Often Should You Change Your Car’s Oil?

Regular oil changes are crucial for a smooth-running engine, maximizing its lifespan and performance. However, knowing the right time isn’t always clear.

Experts recommend changing your oil based on either time or mileage, whichever comes first.

Time-Based Oil Changes

Generally, oil changes are recommended every three or six months, depending on the oil type:

• Mineral oil: Change every 3 months or 3,100 miles (5,000 km).
• Semi-synthetic oil: Change every 6 months or 4,700 miles (7,500 km).
• Fully synthetic oil: Change every 6 months or 6,200 miles (10,000 km).

Mileage-Based Oil Changes

Besides time, mileage also dictates oil change frequency:

• Heavy city driving with frequent stops: Change every 1,900-2,500 miles (3,000-4,000 km).
• Moderate driving with less traffic: Change every 3,100-4,300 miles (5,000-7,000 km).
• Heavy loads, long trips, or mountainous terrain: Change every 1,900 miles (3,000 km).

Note:

• These figures are guidelines. Always consult your car’s owner’s manual for manufacturer recommendations.
• Replace the oil filter with every oil change for optimal filtration.

Factors Affecting Oil Change Intervals

Beyond time and mileage, several factors influence oil change timing:

• Oil type: Synthetic oil lasts longer than mineral or semi-synthetic oil.
• Driving conditions: Harsh conditions like extreme temperatures, dusty roads, or frequent flooding necessitate more frequent changes.
• Driving habits: Aggressive driving with rapid acceleration and braking degrades oil faster.
