Question 1

Is diesel always cheaper to run?

Accepted Answer

Not always. Diesel vehicles get 15-25% better mileage, but diesel fuel often costs $0.10 to $0.30 more per litre. At 1,500 km/month, diesel can save around $23/month, but at lower distances the savings shrink or disappear.

Question 2

Does this include maintenance costs?

Accepted Answer

This calculator compares fuel costs only. Diesel vehicles typically cost $200 to $500 more per year in servicing due to injector and particulate filter maintenance, but their engines often last 50,000+ km longer.

Question 3

What about hybrid or electric vehicles?

Accepted Answer

This tool compares only petrol vs diesel. Hybrid vehicles typically use 30-50% less fuel than petrol, while fully electric vehicles eliminate fuel costs entirely but have charging costs of roughly $0.03 to $0.10 per km.

Question 4

At what mileage does diesel become worth it?

Accepted Answer

Most drivers see diesel savings above 15,000 to 20,000 km per year. At 20,000 km/year with typical prices, diesel can save $250 to $400 annually on fuel alone, which helps offset the higher purchase price.

Question 5

How do I convert between km/L and MPG?

Accepted Answer

Multiply km/L by 2.352 to get miles per gallon (US). For example, 14 km/L equals about 33 MPG, and 18 km/L equals about 42 MPG.
