Even in Australia, colder weather can quietly chip away at your fuel economy and engine performance. It’s not just about temperature… It's about how winter conditions change how your engine runs, and how fuel behaves.
Here’s what’s really going on under the bonnet in winter - and how Proma's fuel treatments can help you drive smarter, cleaner, and further.
Here are some results from tests conducted that show the effectiveness of the MBL8.
Why does winter hurt your fuel economy?
1. Cold engines burn more fuel
Engines run less efficiently until they reach
optimal temperature - and in colder months, that takes longer. The result? More fuel burned
during warm-up, meaning reduced fuel economy from the moment you start the car.
2. Thicker fluids = harder work.
Quick runs to the shops or school drop-offs don’t
give your engine enough time to warm up - so you stay in that inefficient “cold running”
mode the whole way.
3. Shorter trips make it worse
Engine oil and fuel thicken slightly in colder
weather, increasing internal resistance. That forces your engine to work harder, which
increases fuel consumption and hurts your fuel economy.
4. Moisture in your fuel system
Colder temperatures increase condensation in your
tank, which can lead to water contamination and fuel degradation. This not only impacts
performance but can also compromise your fuel economy.
