Efficient Alternatives to Petrol – Part One

Nowadays there are a multitude of engines and fuel sources for our vehicles. Each has their upsides and downsides. This article is meant to be a reference in helping you choose the best powertrain/energy source for your lifestyle. Today, we discuss the merits and drawbacks of diesel.



Drop for drop, diesel fuel contains 50% more energy than petroleum. Although typically more expensive than petrol engines, diesel engines achieve higher fuel economy, especially on the highway, than their conventional counterparts. If you plan on keeping your car for many years and your driving involves a significant amount of highway commuting, then a diesel engine should make your short list. A real world example would be the VW Golf TDI, which achieves 18.6L/km on the highway – just a hair short of a comparable hybrid.

Driving Characteristics:

Diesel engines produce much more torque (the force that throws you back into your seat when you accelerate – than petrol powertrains). This is a boon when driving in the city, where glass-smooth pull can really help you fill holes in traffic. On the whole, however, diesel engines produce less horsepower, and are slower to 100 KPH than petrols. Its important to note that diesels tend to not be as refined as petrol offerings; more vibrations pass through the cabin, especially at idle.


In theory, diesel powertrains tend to be more durable than petrol engines. Unfortunately, in practice – in Israel – gas stations and garages  often water down their diesel supply which drastically reduces the life of the engine compared to petrol and can be expensive to repair. Regarding emissions: manufacturers have many different ways of meeting countries’ emissions requirements. The most common involves spraying a diesel exhaust fluid catalyst into a vehicle’s exhaust flow. This fluid, know as DEF or ADBLU, needs to be refilled every several thousand kilometers in order to for your diesel vehicle to be emission-compliant. Mercedes-Benz in particular are known for their line of very reliable, very efficient diesel engines.

In the next installment, we will discuss the pros and cons of hybrids, and their presence in the Israeli market.
