Fuel-Saving Tips: Diesel vs Gasoline (2026)
By Richard Cuagdan, Mitsubishi Sales Executive ·
Quick answer: These fuel saving tips work whatever you drive. Fuel prices in the Philippines are adjusted almost every week, so habits matter more than timing. Keep tires at the right pressure, accelerate and brake smoothly, cut extra weight, keep up with PMS, and avoid rush hour. Choose diesel for heavy loads and high mileage, gasoline for light city driving.
On October 20, 2026, oil companies rolled back gasoline prices by at least ₱4.30 per liter, while diesel went up by ₱2.60 per liter. Prices remain above the levels seen before the Middle East conflict that began on February 28. In short: diesel ↑, gas ↓, and next week could be different again. The one thing you control is how much fuel you use.
Why prices move every week
Pump prices in the Philippines are adjusted weekly and generally follow world oil prices and supply conditions. That's why diesel and gasoline can move in opposite directions in the same week. Check the Department of Energy's weekly price adjustments before you plan big trips.
7 habits that cut fuel use
Check tire pressure
Under-inflated tires waste fuel. Use the pressure on the door jamb, checked when tires are cold.
Smooth acceleration and braking

Remove extra weight
Unload what you don't need. A trunk full of unused stuff is extra weight every trip.
Keep up with PMS
A clean air filter, fresh oil and a properly tuned engine help efficiency.
Plan your route
Combine errands and avoid rush hour. Idling in traffic burns fuel without moving you.
Don't idle unnecessarily
If you're parked and waiting a long time, turn off the engine when it's safe and allowed.
Keep a steady speed on the expressway
Steady cruising is more efficient than constant speeding up and slowing down.
Diesel vs gasoline: who should choose which
- Choose diesel if you carry heavy loads, haul cargo for a business or rack up high mileage. Diesel engines deliver strong pulling power for work.
- Choose gasoline if most of your driving is light, short city trips and you want a quieter, simpler daily car.
L300 vs Mirage G4: two different jobs
The L300 runs a 2.2L turbo-intercooled diesel (4N14) with a 5-speed manual, built for deliveries and hauling. The Mirage G4 uses a 1.2L gasoline engine and is a light, compact sedan for daily commuting. The right choice is the one that matches your work and route.

Frequently asked questions
Why do fuel prices change every week in the Philippines?
Oil companies adjust pump prices weekly, generally following movements in world oil prices and supply. On October 20, 2026, gasoline was rolled back while diesel went up.
Is diesel or gasoline better?
It depends on use. Diesel engines suit heavy loads, hauling and high mileage, like an L300. Gasoline suits lighter, shorter city driving, like a Mirage G4.
Does tire pressure affect fuel consumption?
Yes. Under-inflated tires increase rolling resistance, so the engine works harder. Follow the pressure printed on your driver's door jamb.
Does using the aircon use more fuel?
AC adds load to the engine, so it uses some fuel. Keep it serviced and park in the shade so it doesn't have to work as hard.
