Your Maruti Alto used to give impressive mileage. But now, every trip seems to burn more fuel than before. If this sounds familiar, you are not the only one. A drop in mileage is one of the most common concerns among Alto owners, especially after a few years on the road.
In this blog, we will explore five real reasons your Alto might be consuming more fuel than usual. These are not assumptions. These are common, verified problems that many Alto drivers in India face. We will also guide you on the spare parts to check or replace to improve fuel efficiency.
Your engine needs clean air to function properly. A clogged air filter restricts airflow, which leads to inefficient fuel burning and poor mileage.
With time, dust and pollution clog the filter, especially in city driving conditions.
Replacing the air filter is one of the simplest ways to restore lost mileage. You can find Maruti Alto-compatible air filters online in both genuine and aftermarket options.
When spark plugs wear out, they fail to ignite the fuel-air mixture efficiently. This leads to incomplete combustion and wasted fuel.
Over time, plugs lose their edge and get covered in deposits that reduce spark quality.
If your Alto has crossed 30,000 kilometers or is over three years old, it may be time to replace the spark plugs designed for Maruti Alto. They are inexpensive and easy to install.
A failing fuel pump may not deliver fuel at the correct pressure. That can cause your engine to run lean or rich, both of which hurt fuel economy.
Fuel pumps wear down with age. Dirt can also block the internal filter, restricting fuel flow.
Look for signs like hesitation or loss of pickup. If your Alto shows these symptoms, a fuel pump replacement may be the fix you need.
Newer Alto models use an oxygen sensor to manage fuel injection. When this sensor fails, the fuel-air mix gets distorted, leading to lower mileage.
An incorrect signal from a dirty or failing sensor causes the engine to run rich, using more fuel than necessary.
If your car has crossed 50,000 kilometers, it’s worth checking the oxygen sensor. You can replace it with a Bosch sensor compatible with the Alto to restore fuel efficiency.
Your tyres directly affect how much effort your engine needs to move the car. Under-inflated or oversized tyres reduce mileage significantly.
Incorrect tyre settings increase resistance on the road and decrease fuel efficiency.
Check your tyre pressure twice a month and stick to the recommended size for optimal fuel economy and safety.
A drop in mileage is frustrating, especially if you rely on your Alto for daily travel. But the solution is often easier than expected. From spark plugs to oxygen sensors, small parts can make a big difference in fuel efficiency.
The best part is you do not need to visit multiple stores. You can buy Alto spare parts online from trusted sources like Autozilla and get them delivered to your doorstep.
Take care of your Alto, and it will reward you with better mileage and fewer fuel stops.
