Essential Car Maintenance: A Guide to Changing Key Components

Proper maintenance is the cornerstone of ensuring your vehicle’s longevity and optimal performance. At Bharat Auto Solution, we understand the importance of keeping your car in peak condition. Here’s an informative guide on when to change critical components like engine oil, air filters, brake oil, spark plugs, coolant, and the timing belt.

Engine Oil: Every 5,000-7,500 Miles

Engine oil is the lifeblood of your car, lubricating the engine’s moving parts and reducing friction. Over time, oil degrades and loses its effectiveness. To keep your engine running smoothly, it’s recommended to change the engine oil every 5,000 to 7,500 miles. Regular oil changes prevent engine wear, improve fuel efficiency, and extend the life of your vehicle.

Air Filter: Every 12,000-15,000 Miles

The air filter prevents dust, dirt, and other contaminants from entering your engine. A clean air filter is crucial for maintaining proper airflow and combustion. Over time, the filter can become clogged, reducing engine efficiency and performance. To ensure your engine breathes clean air, replace the air filter every 12,000 to 15,000 miles.

Brake Oil: Every 20,000-30,000 Miles

Brake fluid is vital for the hydraulic braking system in your vehicle. It transfers force into pressure, ensuring your brakes function effectively. Over time, brake fluid can absorb moisture, leading to reduced braking efficiency and potential system damage. To maintain safe braking performance, change your brake oil every 20,000 to 30,000 miles.

Spark Plugs: Every 30,000 Miles

Spark plugs ignite the air-fuel mixture in the engine’s cylinders, powering your vehicle. Worn or fouled spark plugs can lead to misfires, reduced fuel efficiency, and poor engine performance. To keep your engine firing on all cylinders, replace the spark plugs every 30,000 miles.

Coolant: Every 30,000 Miles

Coolant, or antifreeze, regulates your engine’s temperature, preventing overheating and protecting against freezing in cold weather. Over time, coolant can become contaminated and lose its effectiveness. To ensure your engine stays at the right temperature, flush and replace the coolant every 30,000 miles.

Timing Belt: Every 60,000-100,000 Miles

The timing belt synchronizes the crankshaft and camshaft rotation, ensuring the engine’s valves open and close at the right times. A worn or broken timing belt can cause severe engine damage. Depending on your vehicle’s make and model, replacing the timing belt every 60,000 to 100,000 miles is recommended.


Regular maintenance is essential to keep your car running smoothly and safely.
