Should Car Services Be Done Every Year or Based on km Traveled?
Maintenance is a critical part of owning a car, ensuring optimal performance and longevity. Most manufacturers in India recommend servicing at least every 6 months, but the decision to base services on time or distance traveled is nuanced. Typically, service intervals are based on the distance driven, with frequent small runs even at low mileage requiring more frequent attention.
Why Mileage Matters
Many professionals in the automotive industry recommend basing services on the distance the car has traveled. This is because lubricants degrade over time and distance, regardless of how often the car is used. For example, low mileage cars may still experience reduced lubrication properties as lubricants tend to deteriorate even with infrequent use. This can lead to increased wear and tear on the engine components, including the crankshaft and oil system.
Condensation, fuel combustion by-products, and carbon all contribute to oil contamination, reducing its useful life. While daily use can help burn off some of these contaminants and the filter can capture particles, the oil does not remain "as new". The additives in the oil start degrading once the oil has run in the engine, a process that continues regardless of usage. Oils can also turn acidic over time, which is another reason to change the oil every 12 months, independent of the odometer reading.
Extreme Situations and Environmental Factors
The type of usage and the climate where you live significantly impact how often you need to service your car. In extreme conditions, such as those found in deserts with high temperatures or in harsh environments with frequent hard driving, shorter service intervals may be necessary. For instance, an older car or one operating in desert conditions with summer temperatures of 105°F (40°C) could need servicing every 3000 miles or three months.
The choice of oil also plays a crucial role. Synthetic oil, for example, may require longer service intervals, approximately every 7500 miles or six months. However, aggressive driving, dusty conditions, temperatures over 32°C or constant temperatures below 5°C, and shorter mileage all necessitate more frequent servicing. The type of oil you use (synthetic, semi-synthetic, or regular non-blended) can dictate the appropriate service intervals.
The Role of the Automobile Manual
Despite the importance of following manufacturer guidelines, the best source of information is the owner’s manual in your glove box. It provides specific recommendations based on the make and model of your car, taking into account factors such as usage patterns, driving conditions, and oil type. Always refer to and follow the recommendations in your manual for the most accurate and tailored advice.
Regular maintenance, whether based on time or distance, is crucial for the longevity and reliability of your vehicle. By adhering to the right service intervals, you can ensure that your car runs smoothly and perform optimally, even in challenging conditions.
