Four Wheel Logic

Diesel trucks are worth it for heavy towing and long miles, but light-duty drivers may not recover the extra purchase and running costs.

Yes, diesel trucks suit heavy towing and long miles, while gas trucks fit lighter loads, lower upfront price, and more casual mixed driving.

Diesel pump nozzles are wider than gas nozzles on most car forecourts to reduce misfueling.

Yes, diesel engines usually deliver better fuel efficiency than comparable gasoline engines, especially on long highway trips.

Yes, diesel engines usually run more efficiently than gasoline engines, with higher thermal efficiency and lower fuel use in steady, high-load driving.

Diesel engines usually deliver better fuel economy than similar gasoline engines, especially on long trips and under load, but gains depend on use and model.

No, diesel engines are not always easier to work on; basic service stays simple, but modern fuel and emissions systems add complexity and cost.

Diesel engines are better for long-distance towing and efficiency, while gasoline engines suit lighter cars, short trips, and lower upfront cost.

No, diesel engines are not cleaner overall; they burn less fuel per mile in some trips but create more toxic NOx and fine particles than most gasoline cars.

Diesel engines can be better for high-mile drivers, but petrol and hybrid options suit short trips, low NOx zones, and low-maintenance needs.
