Petrol vs E10
E10 is usually cheaper per litre, though it has slightly less energy content than regular unleaded.
Petrol vs Diesel
Diesel often costs more per litre but may offset that through lower consumption in some vehicles.
Premium vs Regular
Premium fuels cost more and only make sense when the vehicle actually requires them.
LPG economics
LPG can be cheaper, but its value depends on your vehicle setup and driving pattern.
What does a tank really cost you?
Compare the real cost of each fuel for your car and your driving — in dollars, not adjectives.

Picking the right grade matters more than picking the cheapest
Using the wrong octane saves a few cents per litre but can void warranties or hurt long-term economy. Match the grade your owner's manual specifies.
U91 — standard unleaded
For most older Australian petrol cars and many newer commodities. Cheapest mainstream grade. Some 2018+ cars list 95 as the minimum — check your manual before downgrading.
E10 — 10% ethanol blend
Usually 2–3c/L cheaper than U91 but slightly less fuel-efficient (~3% reduction). Most cars built after 2000 are compatible. Older or carburettor-fed engines should avoid it.
P95 / P98 — premium
Required by most European cars, turbocharged engines and high-compression sports cars. P98 is the highest octane available at most stations. Using P95+ when not required is wasted money.
Diesel — fleet and SUV
Diesel engines only. Tracks crude oil and freight demand more closely than petrol, so its cycle behaviour is very different — usually no weekly cycle, just gradual moves with wholesale prices.
