Car Mileage Tips:  Everyone runs after car mileage but most people have problems regarding mileage. In such a situation, you need to know about speed.

Engine Type: Diesel engines generally give better mileage than petrol engines.

Transmission: Cars with manual transmissions generally give better mileage than cars with automatic transmissions.

Tire Pressure: Properly inflated tires provide better mileage.

Driving habits: Aggressive driving (rapid acceleration and braking) can result in poor mileage.

Generally, most cars get the best mileage at a speed of 80–100 kilometers per hour (50–62 mph). At this speed, the engine is running at its most efficient rate and air drag is minimal.

Here are some additional tips that can help you improve your car's mileage:

Drive slowly and avoid sudden braking or acceleration.

Reduce the use of air conditioning.

Get your car maintained regularly.

Avoid getting stuck in traffic.

Carry light luggage.

It is also important to note that mileage does not depend only on speed. Other factors listed above also play an important role. By making slight changes in your driving habits, you can improve the mileage of your car to a great extent.
