Key Differences

Derv is specifically formulated for the use in road vehicles with diesel engines, focusing on characteristics like low sulfur content and cetane number to reduce emissions and improve engine performance. On the other hand, diesel can refer to any fuel used in diesel engines, not limited to road vehicles but also including applications in marine, industrial, and heating systems.
While DERV is tailored to meet strict regulatory standards for vehicles, including additives that enhance performance and reduce wear, diesel fuel, in its broader usage, may have varying specifications depending on its intended application, such as different sulfur content levels or cetane numbers.
Derv's pricing and taxation are often governed by regulations aimed at road transport, making it sometimes more expensive due to environmental levies. Conversely, diesel fuel used for other purposes, like heating or in off-road machinery, may have lower taxes, reflecting different environmental and economic policies.
In terms of availability, DERV is predominantly found at public filling stations, readily available for commercial and private road vehicles. Diesel, however, can be sourced from a broader range of outlets, including those catering to industrial or agricultural needs, where the specifications might differ from road-vehicle fuel.
Derv's composition includes additives to lower the freezing point and improve ignition quality, catering to the demands of modern road vehicles. Diesel for other uses might not have these specific additives but could include others that are suited for the particular engine or application it serves.

Compare with Definitions

Derv

DERV includes additives to improve engine efficiency and reduce wear.
The latest DERV formula helps my car start better in cold weather.

Diesel

Diesel's energy content varies depending on its source and grade.
Industrial diesel engines require fuel with a high energy content.

Derv

Subject to road fuel taxation, DERV is slightly more expensive.
Filling up with DERV costs more due to environmental taxes.

Diesel

Diesel for marine engines often has a different formulation.
Our boat requires marine diesel, which is different from what trucks use.

Derv

A diesel fuel variant for road vehicles, designed to meet automotive standards.
My truck runs smoothly on DERV due to its high cetane number.

Diesel

Bulk purchasing options are available for industrial diesel needs.
Our company buys diesel in bulk for our fleet of construction machinery.

Derv

Available at most service stations, DERV is easily accessible.
I can find DERV at any nearby fuel station.

Diesel

A fuel type used in diesel engines, not specific to road vehicles.
The diesel generator powers the entire building during outages.

Derv

DERV's low sulfur content helps in reducing emissions.
Using DERV has significantly lowered my car's emissions.

Diesel

Heating oil, a form of diesel, is used in furnaces and boilers.
We stock up on heating oil before winter each year.

Derv

(UK) Diesel fuel for motor vehicles.

Diesel

An internal combustion engine in which heat produced by the compression of air in the cylinder is used to ignite the fuel
A diesel locomotive

Derv

Diesel oil used in cars and lorries with diesel engines; from d(iesel) e(ngine) r(oad) v(ehicle)

Diesel

A diesel engine.

Diesel

A vehicle powered by a diesel engine.

Diesel

Any of various fuels used to power diesel engines, especially one derived from petroleum.

Diesel

To continue running after the ignition has been turned off, as when an open throttle supplies fuel to an engine that is still sufficiently hot to ignite it.

Diesel

To drive a diesel-powered vehicle
We dieseled through the countryside.

Diesel

To refuel a diesel-powered vehicle. Often used with up.

Diesel

A fuel derived from petroleum (or other oils) but heavier than gasoline/petrol. Used to power diesel engines which burn this fuel using the heat produced when air is compressed.

Diesel

(countable) A vehicle powered by a diesel engine.

Diesel

A rider who has an even energy output, without bursts of speed.

Diesel

Diesel

(slang) A particular cannabis hybrid.

Diesel

To ignite a substance by using the heat generated by compression.

Diesel

(automotive) For a spark-ignition internal combustion engine to continue running after the electrical current to the spark plugs has been turned off. This occurs when there's enough heat in the combustion chamber to ignite the air and fuel mixture without a spark, the same way that heat and pressure cause ignition in a diesel engine.

Diesel

A type of internal-combustion engine in which the air drawn in by the suction stroke is so highly compressed that the heat generated ignites the fuel (usually a heavy oil), the fuel being automatically sprayed into the cylinder under pressure. The Diesel engine has a very high thermal efficiency.
