“Buying a new vehicle is a different thing and maintaining one is entirely different”, this is a free of cost friendly advice which anyone of us can easily come across after we buy our new set of wheels. We definitely agree on this piece of counsel and also at our end recommend following proper maintenance practices.
What most of the owners are concerned when it comes to maintenance? Talk to any owner and tell them that the tyres or battery or brakes or some minor electronics of their vehicle are not proper. They will take it with a pinch of salt and give a response of “will get it repaired” in an ignoring attitude. Now change the name and tell them that you found something wrong with the engine and the owner for once will sit and listen to what you have just said. What’s the reason for this attention? Haha, two they are; engine life concern and the costs of repairs. It’s a fact that engine repairs simply cost a bomb if are required to be done.
We are not telling you a hundred or two of practices (some are really weird) which will keep your engine going on and on but will emphasize on the easiest to follow which will enhance the engine life at its best. “Regular servicing and don’t revv high” is all we have to say. Getting your vehicle serviced at right intervals and properly is the first mantra and sedate driving without high revving is the second.
What is high revving? High revving is basically referred to high RPM driving of the engine. The concept is simple, higher the RPM means a higher engine speed, which in turn results in higher friction and heat losses and this finally results in a lower component life. No false hopes or information, but the Naked Truth is that higher RPM you drive on, lower gets your engine life. Where to find the engine RPM? Well, most of the modern vehicles do come with a tachometer with readings like 1,2,3 and so on along with the speedometer and these numbers when multiplied with the multiplication factor mentioned on the meter converts into the engine speed.
Engine life factor is what gives exact insight of the situation and can be given as:
Engine Life Factor (ELF) = (100,000/Maximum RPM x Compression Ratio)
In the above equation, the terms 100,000 and compression ratio are fixed and all that can be changed is Maximum RPM. Since Maximum RPM for any engine depends more on the user at the time of driving because all manufacturers can do is lock the maximum RPM at a specific number, but the engine speed solely depends on the driver.
Example: Two people are driving at 60 kph in their car, one is driving at 4000 rpm in 3rd gear while other is driving at 1500 rpm in 5th gear with an engine having compression ratio of 10. So the ELF for first and second will be 2.5 and 6.66 respectively. This way, one can find that the car being driven at a lower engine speed is having a higher engine life factor.
All in all, driving in higher gears not only give you an advantage in terms of lower fuel consumption but also gives an enhanced engine life. That’s what we call true double protection and that also without doing anything much different than what you regularly do; driving!
