Lifetime gear oil isn’t infinite
Nowadays car manufacturers say that the transmission oil is life. That however doesn’t mean it will last the life time of the car. Like every fluid, the transmission oil’s properties also change with time as it is subjected to a heat cycle. The frequency to change the gear oil is mentioned in the service manual and varies from car to car. Also remember the fact that the oil deteriorates not only with mileage, but also with age, so please make sure you adhere to what is mentioned in the manual.
Driving through waterlogged roads can damage clutch & gearbox
Unlike the engine which is completely sealed, the gearbox & clutch assembly are just bolted on. So when you drive through roads having high levels of water, there is a possibility of water seeping into the clutch & gearbox. This will make it tougher to operate the gears till the water dries. The water also shortens the life of the transmission fluid.
Do NOT crank your car if stuck in water
When it rains in India, roads get water logged. Mostly everyone has to wade through water to make it to their destination. While wading through water, if your car shuts down, don’t try cranking it unless the water level is below that of the silencer. If you try cranking a car when stuck, water will enter into the engine via the exhaust and could cause it to seize.
Cracked alloy wheels can’t be repaired
Most cars nowadays come equipped with alloy wheels. Given how bad our road conditions are, they may crack if subjected to severe impact. Once an alloy is cracked, it cannot be repaired. Small bends could be repaired, but not many people repair them. Steel wheels on the other hand do not crack, they only get bent & can be repaired.
Under inflation of tyres cause more tyre bursts than over inflation
Unlike what most people would think, if your tyres are under inflated, they have more chances of bursting than if your tyres are over inflated. When your tyres are under inflated, the contact area of the tyre with the road increases, which means the friction too will increase. With this increased friction, the heat in the tyre will also increase. If you drive for long distance, especially on cement roads, the tyres will heat up a lot & will eventually burst.
Incase of over inflation, a tyre won’t burst if it is just a little over inflated. If it is over inflated by a lot, then as the temperature rises, the air will expand putting excessive pressure on the tyre and increasing its temperature which will eventually burst if used over long periods of time.
