If you’ve ever asked yourself, "Which is more fuel-efficient, diesel or gas?" or "Which is cheaper in the long run?"—you’re not alone. Filipino car buyers and sellers often weigh these fuel types carefully, especially as fuel prices continue to fluctuate and electric vehicles (EVs) enter the market.

3 Key Takeaways

1. Diesel cars are generally more fuel-efficient, but petrol (gasoline) cars may be cheaper to maintain long-term for city drivers.
2. Ownership cost varies by usage—diesel is ideal for long-distance drivers, while gas suits occasional urban use.
3. EVs are emerging as a cost-effective and eco-friendly alternative—ideal if you plan to future-proof your purchase.

Fuel Types in the Philippines: Gas vs Diesel

In the Philippines, most vehicles run on either gasoline (commonly called “gas”) or diesel. Both fuels are readily available, but they serve different purposes depending on the car type, usage, and even location.

1. Gasoline (Petrol): Commonly used in small cars, sedans, and compact SUVs.
2. Diesel: Preferred for larger vehicles such as pickup trucks, vans, and SUVs used for long-distance travel or commercial purposes.

Why Do We Have Different Fuel Types?

Gasoline engines and diesel engines are built differently:

1. Gas engines use spark plugs and are generally quieter, smoother, and cheaper to maintain.
2. Diesel engines rely on compression ignition, offer more torque, and are more fuel-efficient over long distances.

The key reason for this separation is efficiency vs. refinement. Diesel provides better mileage, while gas provides smoother acceleration and is more responsive in traffic.

Which Is More Fuel-Efficient in the Philippines?

Diesel engines usually get 20% to 35% better fuel economy than gas engines. That means fewer refills and lower fuel cost per kilometer—ideal for high-mileage drivers like those in logistics or frequent travellers between provinces.

However, gasoline engines are more efficient in stop-and-go city driving and are often lighter, making the cars cheaper upfront and easier to maintain.

Total Cost of Ownership: Diesel vs Gas

Let’s compare key points over a 5-year ownership period:

*Prices fluctuate based on oil market trends and government subsidies.

What About Electric Vehicles (EVs)?

EVs are becoming more accessible in Metro Manila and other urban hubs. They offer zero fuel cost, minimal maintenance, and are often exempt from certain taxes and road restrictions. However, limited charging infrastructure and higher upfront costs remain key challenges.

That said, if your driving pattern is predictable and urban-focused, EVs could soon become a more viable and cost-effective alternative to gas or diesel.
