Diesel engines have the highest thermal efficiency of all internal combustion engines which means they tend to be more efficient than petrol engines.
Efficiency aside, there are other factors that make diesel engines different to petrol engines;
Because diesel engines suffer from carbon build up which can cause damage to the engine – it’s important to stick to a regular service schedule, so any problems can be identified early. Neglecting to do so can lead to very expensive repairs.
Diesel vehicles have a different type of plug called a Glow Plug….What’s a glow plug?

Yes. Oils that are created for use in diesel engines are different to oils for petrol engines, they have extra additives to help clean the engine and more.
You might have a worn or damaged turbo charger shaft seal, which could lead to bigger problems.
While certain models can be initially more expensive than a petrol vehicle and cost slightly more for quality servicing, in the long-term, diesel vehicles usually use up to 30% less fuel and have a longer engine life as well as lower CO2 emissions and greater towing abilities.
