Best answer: Will a diesel engine last longer than a gasoline engine?

Diesel engines do last longer than petrol ones. Diesel is a light oil and when burned and used as fuel by the vehicle it lubricates the parts of the engine. This prolongs the life of the engine. … While diesel engines typically last longer they are more costly to repair.

How many miles can a diesel engine last?

1,000,000-1,500,000 miles

What is the advantage of a diesel engine over a gasoline engine?

On average, diesel engines are more fuel efficient than gasoline vehicles because they generate more power from less fuel due to their higher compression rating. With the addition of modern high-pressure fuel-injection systems, it is possible to get even better fuel economy.

Which is better gasoline or diesel engine?

Putting Gasoline in Diesel Fuel

Let’s say you accidentally drop a small amount of gasoline into your diesel fuel. … This means the diesel fuel will prematurely ignite in the diesel engine, which can lead to engine damage. Gasoline contamination can also damage the fuel pump and mess up diesel injectors.

Is buying a diesel a bad idea?

Modern diesels are just as clean as equivalent petrol engines in terms of NOx emissions. Diesels generally produce lower amounts of CO2. Diesels achieve excellent fuel economy at motorway speeds. It can absolutely be worth buying a diesel car depending on what you use the car for.

Excessive warm-up times can really sap the diesel fuel used, so avoid idling to help save fuel. Use shore power when you can.

Should you drive a diesel hard?


Why diesel engines have more torque?

The higher turbo boost pressure, high compression ratio, and greater heat content of the fuel all add to the generation of cylinder pressure that is substantially higher than in gasoline engines too, but it is this continued injection of fuel that really makes the big torque numbers for diesels.

Why do diesel engines accelerate slower?

Diesel engines are generally heavier than their petrol counterparts making them slower. … As a consequence of a higher compression ratio (longer stroke), diesel engines produce more torque which means you get more acceleration off the line.
