Cars clocking 1,00,000 kilometres on the odometer used to be a sign that the car has approached its end of life. 1,00,000 km mileage meant that the wear and tear have taken its toll on every part of the car. But, with technological advances, the cars manufactured today have greater durability and reliability. So there is no need to panic, you can still drive that to the 2,00,000 km mark comfortably. All you need to do is take proper care of the car at the 1,00,000 km mark which in turn will help you go the extra 1,00,000 km. Almost all the advice you need is available in the owner’s manual, as it provides MTBF(Mean Time Between Failures) for all the car parts. MTBF provides with a mileage mark at which certain parts needs to be replaced. Below is the list of things that needs to be taken care of for the vehicle to perform better in future and to avoid any breakdowns.


Tyres have high wear and tear since its the only part of the car that is touching the ground. If you are still using the original tyres it needs to be replaced as the tread might not be deep enough for proper on-road grip. As the car has high mileage under its belt the wheel alignment needs to be checked and corrected if necessary. Misalignment of wheels will cause numerous problems. It will lead to high wear and tear on tyres, undue pressure on suspension and also affect how the vehicle handle. All of these combined will result in more expensive repairs in future. All of this can be avoided by a simple check of wheel alignment.


Fluids are the lifeblood of the car. It is present in almost all moving parts. It provides for lubrication and smooth functioning of all parts. As the vehicle racks up mileage dirt and debris starts to accumulate in the fluids, so it’s absolutely necessary to replace the fluids at recommended mileage mark. At the 1,00,000 km mark, it’s important to use High-Mileage oils, these are tailor-made for the vehicles which have reached 1,00,000 km mark. These are specially designed to recondition seal and stop leaks, and also to clean the sludge from an older engine. Another fluid that needs to be replaced is the Transmission fluid. Transmission fluid lubricates the transmission and helps cool it down. As the car has high mileage the transmission fluid may have reached its performance limits. You will face difficulty shifting gears, loud transmission noise, fluid burning smell or leaking transmission fluids. If the transmission is damaged then its a very high-cost repair, so to avoid it just get the transmission fluid replaced. Brake fluid is also important for the proper functioning of the car. Since most modern cars have hydraulic brakes and clutch. They operate at a very high temperature and protects major components from corrosion. So it’s replacing it will help in the longevity of the car. Last but not the least the Coolant needs to replaced. As it helps in keeping the engine temperature at a working condition, thus increasing the engine life.

Timing Belt and Hoses

Timing belt plays a critically important role in engines performance. In simplest terms, it controls when the camshaft and crankshaft rotates and cylinder valves open and close. It needs to be replaced at the manufacturer recommended interval which is generally at the 1,00,000 km mileage mark. If it is damaged during driving it may damage other parts leading to very high repair cost. Hence its very important to get it replaced at the recommended time. Also, there are belts and hoses which are all made of rubbers and play a vital role in cars functioning. Even though the rubbers are designed to work at high temperatures it is of absolute importance to notice any damage to it and replacing it if necessary.

Shocks, Struts, Exhaust System, Catalytic Converter, and Oxygen Sensors

Shock and Struts are wear items. Apart from providing riding comfort they play a crucial role in handling and stopping distance of the car. Since the car has clocked high mileage the exhaust system will get clogged, narrowing the exhaust passage which in turn puts pressure on the engine to work hard to push the exhaust gases through, hence lowering the fuel mileage. Oxygen sensors and catalytic converter are part of the emission system. Oxygen sensor help in peak performance of the engine regulating emissions and catalytic converter traps and converts harmful pollutants. All the above needs to be checked and replaced accordingly.


There are 4 different types of filters in a car. These are Engine Air filter, Cabin Air filter, Oil filter and Fuel filter. Engine Air filter as the name suggests it filters the air that is taken in by the engine for combustion. Anything that has an influence on the combustion will have a direct impact on the fuel efficiency as well. This filter prevents any abrasive particles such as dust and dirt present in the air from getting into the engine. If the vehicle is used in a high pollution area it is advised to clean and replace it regular intervals, since high pollution means higher dust particles. Next is Cabin Air filter which looks after the air quality inside the cabin. It filters out any dust particles and pollens thus protecting the passenger’s health. Now, moving to the fluid filtration Oil filter plays a key role. Oil filter plays a much more important role than the air filter in protecting the engine. Oil is needed to lubricate and cool the engine, as the engine consists of moving parts. And with any moving parts, there is bound to be friction which further results in metal shavings. So when the engine oil is cycled back the Oil filter blocks the metal shavings getting back into the engine which may cause damage to the engine. Another fluid filtration component is the Fuel filter. Fuel filters are different in petrol and diesel engines. The common purpose of the Fuel filter is to help the performance and lifespan of the engine. The petrol and diesel filters differ in the function that is the petrol fuel filter simply removes impurities that come with petrol that is put in the vehicle, whereas diesel fuel filters play a much bigger role in preventing corrosion by removing any build up of water inside the engine. These trivial parts may seem benign but any failures of these parts will cause heavy damage to the car in the long run.So it is recommended to check them properly and if needed have them replaced.

Spark Plug and A/C

The plasma of the spark wears out with time and thus requires more energy to fire up. Its necessary to replace the spark plug so that the car starts up with ease. And A/C is very important in places with high temperature, as it makes the ride comfortable. A/C works on thermodynamics but let’s not get into the science of it. If you are one of these people who prefers a cold breeze inside the cabin it’s absolutely important to get compressor clutch as it plays a vital role cooling of the air that is pushed into the cabin. Also, check with the service centre if it needs to be recharged. Recharging the A/C will result in better performance, providing cooler air inside the cabin at a much efficient rate.

Taking care of these important parts will help you and the car a long way without any hiccups. Once you made sure that these parts are functioning properly getting to the 2,00,000 km mark will be a breeze. You will be safe from any unexpected breakdowns and high repair costs.
