Your Car Is Secretly Burning More Fuel Than It Should

Cover image

Fuel prices aren’t exactly cheap these days. Even with Budi95, it still makes sense to be careful with fuel consumption because quotas and subsidies can change at any time. A fuel-efficient car can help reduce your running costs, but no matter how efficient your car is, poor maintenance will eventually make it consume more fuel than it should.

Signs You Should Have Your Fuel System Checked

Some people believe there’s a big difference in fuel economy between RON95 and RON97. While there can be some variation, it’s usually not the biggest factor.

In reality, fuel efficiency is often affected by a combination of smaller issues that add up over time. Things like incorrect tyre pressure, a dirty air filter, old engine oil, faulty oxygen sensors, brake drag, or inconsistent fuel injection can all quietly hurt your fuel economy. These are the silent killers of fuel efficiency.

If you're experiencing any of the symptoms below, it may be time to have your car inspected by a professional:

  • A full tank doesn’t last nearly as long as it used to
  • The car feels sluggish when you press the accelerator
  • The check engine light comes on
  • The engine sounds rough while idling
  • A burning smell near the wheels or brakes
  • In a hybrid vehicle, the engine keeps running even when the battery should be handling idle operation

Even if you’re not experiencing any of these issues, regular inspections are still worthwhile. Preventive checks can help identify small problems before they turn into costly repairs. For added convenience, you can bring your vehicle to BGarage for a professional inspection.

What Does BGarage Check?

BGarage technicians are trained to identify issues that affect fuel efficiency. You don’t have to wait until something goes seriously wrong before getting your car checked.

During the inspection, technicians may examine:

  • Tyre pressure and tread condition
  • Engine oil level and condition
  • Fuel and air filters
  • Battery voltage
  • Brake system condition
  • ECU fault codes and vehicle diagnostics

Why These Components Matter

Tyre Pressure

Underinflated tyres create more rolling resistance, forcing the engine to work harder and burn more fuel. They can also affect handling and braking performance.

Engine Oil

Old or incorrect engine oil increases internal friction within the engine. Using the right oil and replacing it on schedule helps the engine run smoothly and efficiently.

Air Filter and Spark Plugs

A clogged air filter or carbon-covered spark plugs can disrupt the air-fuel mixture. This often results in sluggish acceleration, reduced performance, and higher fuel consumption.

ECU Fault Code Scanning

Modern vehicles rely on numerous sensors to keep the engine running efficiently. Sometimes, a sensor can detect a problem before you notice any symptoms. Components such as the oxygen sensor, MAF/MAP sensors, ignition system, EGR, DPF, hybrid systems, and more can reveal underlying issues that may be affecting fuel economy.

What about diesel and hybrid car?

Whether you drive a petrol, diesel, or hybrid vehicle, regular inspections are important.

For diesel owners who have recently started using B15 biodiesel, there’s generally no need to worry. Vehicle manufacturers have stated that compatible engines are designed to handle the fuel. However, timely maintenance remains essential, particularly when it comes to checking fuel filters, injectors, EGR systems, and DPF components.

Hybrid vehicles are also not immune to efficiency issues. While they are designed to save fuel, neglected batteries, motors, or electrical systems can reduce the effectiveness of regenerative braking and force the engine to use more fuel than necessary.

BGarage Inspects, Then Recommends

BGarage's echnicians don’t guess, they inspect.

Every vehicle is checked thoroughly to identify the real cause of excessive fuel consumption. Once the root issue is found, recommendations are made based on what actually needs attention, whether that means repairing or replacing a specific component.

That way, you only spend money where it matters.

A fuel-efficient car starts with proper maintenance. If your vehicle feels sluggish, burns through fuel too quickly, or simply doesn’t feel as efficient as it used to, bring it to BGarage for an inspection and get to the root of the problem.
