Many people like to drive in most casual way as possible. These are the driving habits that effect the health of your car badly. The top worst driving habits to avoid are mentioned below:
1. Sudden Acceleration
Though it may thrill, it puts heavy load on the car's mechanical components and it burns a lot of fuel, too. Sudden acceleration increases speed of the car quickly and may also need you to suddenly slow down the car soon after reaching a high speed, which may be achieved with sudden or harsh breaking; this is also not very healthy for car's breaking system.
2. Moving Before the Engine is Warm Enough
Waiting for 30-60 seconds after starting the car is a good idea. It allows the engine oil to circulate fully throughout the engine and also warm up. Moving the car immediately after starting the engine should be avoided as it is harmful for the engine.
3. Sudden Shift from Reverse to Drive
Many of us have done it and it may sound like efficient driving. It may be saving a few seconds of your time, too, but suddenly shifting gear from Reverse to Drive can damage your car's gear system. Hence it is highly recommended to let the car to come to a complete stop before shifting from Reverse to Drive or Drive to Reverse.
4. Keeping the Fuel Tank Low
You may ask 'how can it really matter whether the fuel tank is low or full?' It does actual matter for some cars. In fuel tanks for some cars, two fuel pumps are fitted - one at the tank surface and one higher than that. Both the pumps are running together at all the times. If you keep the tank low in fuel, the upper fuel pump will not be pulling in fuel and thus may get dry enough and damage. Therefore, it is a good idea to keep at least half of your fuel tank filled with the fuel all the times.
5. Not Using the Parking Break
It is highly recommended to always use the parking break when you park your car. Putting the gear in 'Park' mode does stop the car from moving but it puts a lot of pressure on a little piece of metal in the transmission system, which may wear out quickly or even break. So, always use your vehicles's parking break when you park your car.
6. Carrying Too Much Weight
When the car is heavily loaded, a lot of stress is put on the car's suspension system brakes as well as the engine. Make sure to load your car with weight that will not pull down the car too much.
7. Continuous Use of Breaks
People often use continuous breaking while going downhill. This generates too much heat in the car's breaking system, and cause risk of wear or break-pad breaking. The alternative and better solution is to shift into a lower gear
These were the top 7 bad driving habits that you should avoid. Hope you found these useful.

Diesel Engine vs Gasoline Engine
Are Diesel Engines Efficient vs Gasoline Engines? The rivalry between the gasoline engines and diesel engines has been there since the birth of both the engines, and the trophy of this competition keeps on changing its winner. This cat and mouse race between both the major types of internal combustion engines does not seem to end, as both the engines have their pros and cons. It now depends upon the user to select the engine as per the use requirements. However, still the factor of efficiency can be termed as a gauge to appreciate one kind of engine over another. The modern times are witnessing now the enhanced efficiency of gasoline engines over the diesel engines.
Highway Usage Edge
When both the gasoline engines and diesel engines are compared with regards to the factor of efficiency at higher speeds, especially for long distance travelling, the efficiency of the diesel engines has always been appreciated over the gasoline engines because at higher speeds higher compression ratios coupled with lean fuel burning due to rich air in the mixture has always given the diesel engines an inherent edge over the gasoline engines.
Future of Gasoline Engine
This inherent edge in diesel engines could not be overcome except for revolutionary introduction of the hybrid fuel gasoline engines. However still as a whole diesel engines enjoy the efficiency edge over the gasoline engines. The modern times though are witnessing the minimization of this edge of diesel engines over gasoline engines and the future of gasoline engines is expected to be much brighter than the diesel engines. It is also due to the stricter emissions regulations which are making diesel engines proving to be less efficient due to the exhaust of diesel engines, and this gap of efficiency between the two engines is expected to close within the current decade.
Newer Technology in Gasoline and Diesel Engines
Newer technology being introduced in the gasoline engines is ever changing at a very fast pace amalgamated with lots of versatility such as variable valve lift timed ignition, gasoline direct injection, multi-port fuel injection systems and introduction of turbochargers have added a lot to the efficiency of gasoline engines. Also affiliated improvements in the electronics and metallurgy have further enhanced the efficiency of gasoline engines. Further research towards lean burn combustion and the innovation in the technology of homogeneous charge compression ignition further decreases the gap between the efficiency of the diesel engines and gasoline engines. Research on shifting of gasoline engines on more energy dense fuels is also underway which can further prove to be a milestone in taking an edge over the more

When to Replace Car Tires with New Tires?
Cars are directly dependent upon tires for their movement as humans are dependent upon shoes for the same. Hence car tires play a crucial role in numerous driving phases, may it be drifting, normal driving, acceleration, deceleration, braking action, aiding suspension and steering response; car tires are the major component which are there playing their role in every movement of the vehicle and bearing all the load and all types of frictions upon them directly. It is therefore very necessary that to buy car tires the tires selection be done with due consideration for achieving a safe and comfortable drive. Now the question of the questions is that how and when to replace the car tires which are worn out, as the tires should be regularly checked for their wear and tear. Some of the best tips to determine whether it's time to buy new tires are mentioned below:
Car tires should be inspected on regular intervals may it be weekly or monthly but must be checked. One important aspect about the car tire
May it be hard wearing car tires or environmentally friendly car tires, almost all of the good quality car tires are manufactured with wear indicators embossed in between the threads base. Car tires should be regularly checked for the wear in accordance with the wear markers, when tires tread is about to reach the level of the wear marker, replace the tires as after that the car tires are no more road worthy and should not be blamed for any accident. Hence the tires should be replaced when there is around 3 mm of car tire tread is remaining, to be on the safer side.
Life of the Tire
Almost all of the car tire manufacturers claim that the life of car tire is five years from the date of manufacturing. It is also mentioned on the side wall of the tires. The tires should be thus immediately replaced when that date is over, even though if the wear in the car tires may not be that much. As after that the car tires performance is compromised and safety concerns too. The manufacturing date is mentioned as a four digit number in which the first two numbers indicate the week of manufacturing and the second later numbers indicate the year of the car tires.
This guide explained when car tires should be replaced. Hope you found it helpful.

Spark Plug Function
Engines which are the main driving force of the modern day vehicles comprise of two main types, depending upon the type of the fuel being used in the engine. Hence the engines can be categorized as spark ignition (Petrol) vehicles and compression ignition (diesel) vehicles. And the most important part in the petrol vehicle which ensures constant sustainable life to the petrol engine cars is the spark plug which is the sole agent responsible to ignite the petrol and make it burn which in turn will generate the power for the petrol vehicles. Best spark plugs available in the market are used for getting the optimum performance of the cars. The Spark plugs are therefore the most crucial part of ignition system of cars. Also since the spark plugs are one of the directly exposed to combustion parts of the engine, the spark plugs are designed to bear high temperatures of combustion while an engine is running.
Spark Plug Construction
There are following three main parts of a spark plug
- Center electrode
- Ground electrode
- Insulation between two electrodes
Moreover, there is a body shell, the sealing ring and the gasket washer. The insulator between two electrodes, play an important role in maintaining temperature. Outer insulation prevents hot gases from leakage. Spark plug wires attach it with engine and make it the part of whole ignition system.
If continuous ignition occur in spark plug, it would be difficult to control temperature of central electrode as it is constantly increasing. Therefore for maintaining certain temperature level, Spark plug gaps are important. There must be some resistance in combustion to make spark gaps possible.
Therefore a best spark plug should have following characteristics.
- Should maintain certain (engine operating) temperature
- Insulation among electrodes
- External insulation
- Supports reasonable spark gaps
Spark plugs require proper maintenance and need to be replaced for smooth functioning of car engines. One must know spark plug symptoms to know when to replace a spark plug. There are some simple steps that one can follow to check whether spark plug needs to be replaced or not.
Due to ignition process exhaust gases are released, which is the main source of accumulation of carbon gases on spark plug, which in result make it covered with black color (carbon accumulation). This is the indication that the spark plug should be cleaned or replaced if the engine is not delivering the optimum performance, as the direly required spark plug replacement increases the engine efficiency.
In a nutshell the spark plugs and spark plug wires are two decisive things that require proper maintenance and are the backbone of engine efficiency. After certain time intervals these must be replaced to enjoy power of the acceleration on petrol.

After buying a brand new vehicle, its major expense is of fuel, which can be gas, petrol or LPG etc. We are always concerned to save fuel of our car. As fuel prices are increasing, it will be an art that how car owners mange their fuel requirements, without disturbing their budget and travel routines. The following tips will help you save car fuel and increase fuel economy.
Avoid over speeding:
Speed above to certain limit can increase fuel consumption exponentially. Moreover, over speeding is negatively linked with gas burning up. You can verify the fact that fuel consumption is less when you are driving your car with medium speed like 60-70 kms/hour, as compared to high speeds.. Hence for smart car fuel economy avoid rash drives, useless racing or simply over-speeding.
Check and maintain tire pressure:
With the time, tires lose air pressure and sturdiness. Old tires have more rolling resistance; this leads to more fuel consumption. Make all tires of your car checked by accurate gauge regularly. Continuous running of car also heats up the tires. You can also overcome this thing by using tube-less tires but with these tires it does not mean these do not require tire pressure checks.
Don't use unnecessary accessories:
If you have equipped your car with some extra accessories, AC can be an example; fuel burning will then be greater. This can be major issue for small cars. Therefore, for good car fuel economy additional facilities and extra load should be avoided.
Changing gears again and again will tend to vary RPMs (Resolution per minute) which automatically use more fuel. Maintaining car speed is best tool to save care fuel efficiently and effectively.
Cheap fuel and filling stations:
In under developed courtiers you would observe large variation in petrol quality from one filling station to other. Impure petrol is dangerous for your vehicle as well as it can increase fuel consumption as well. Always refill the fuel by well known filling station. You must be satisfies about quality of petrol. Cheap fuel will definitely be of poor quality. Be careful! It's the matter of your convenience.
Check air filter:
Unclean air filter halts flow of air into the engine. It is quite easy to check how old and dirty air filter is. Simple remove the filter and place in sunlight if light is not passing through it, you need to change it .A dirty air filter restricts the flow of air into the engine, which harms performance and economy. Dirty filters damage environment too.
Car care fuel economy is totally an art. If you are good at it, you would enjoy all your drives with little regard to inflating fuel prices.
