Frequently Asked Questions
Is diesel cheaper than petrol per mile?
Diesel vehicles typically achieve 20-30% better fuel economy than petrol vehicles, offsetting higher fuel prices. On average, diesel costs 10-25% less per mile despite being $0.20-$0.50 more expensive per gallon.
What is good diesel mileage?
Good diesel mileage varies by vehicle: Cars (45-60 MPG), SUVs (30-40 MPG), Pickup trucks (25-35 MPG), and Commercial trucks (8-12 MPG). Modern diesel engines are significantly more efficient than older models.
When does diesel make sense over petrol?
Diesel is economical if you drive 15,000+ miles annually, do frequent highway driving, haul heavy loads regularly, or plan to keep the vehicle 5+ years. The higher purchase price is offset by fuel savings and longevity.
How much does diesel maintenance cost compared to petrol?
Diesel maintenance costs 10-15% more due to expensive oil changes, fuel filters, and DEF fluid. However, diesel engines last 2-3x longer (200,000-500,000 miles), making long-term costs competitive.
