Petrol or Diesel?

Petrol or Diesel?
16 January 2015

For an off- roader, a powerful engine is of less importance than one might think. The old Land Rovers had small engines, but their off-road reputation is enviable. This is because the engines, although small, could deliver their power and torque at very low rpm, and this is what is important when driving off-road. But what about petrol vs diesel engines?

Petrol Advantages:

  • Quieter
  • More powerful than similar sized diesel engine
  • More mechanics understand petrol engines
  • Easier roadside maintenance and repairs
  • Less expensive to maintain, repair or overhaul.

Petrol Disadvantages:

  • Develops maximum torque at a higher rpm
  • Higher fuel consumption
  • Non-availability of petrol in certain areas (especially unleaded)

Diesel Advantages:

  • Torque characteristics - maximum torque at low rpm
  • Excellent engine braking characteristics
  • Normal electrical problems caused by wading are non-existent
  • More economical - longer range
  • More readily available in certain remote areas

Diesel Disadvantages:

  • More noisy
  • Less power than similar sized petrol engines
  • Limited roadside maintenance and repairs
  • Fewer mechanics understand diesel engines
  • Expensive repairs and maintenance
