Should a person be found using this untaxed diesel fuel for a typically taxed purpose (such as "over-the-road," or driving use), the user may have to pay a heavy fine.
High compression ratios and throttleless operation generally result in diesel engines being more efficient than many spark-ignited engines.

Such synthetic diesel has 30 percent lower particulate emissions than conventional diesel (US- California).
That car and a later Cummins Diesel Special are on display at the Indianapolis Motor Speedway Hall of Fame Museum.
Special low temperature diesel contains additives that keep it in a more liquid state at lower temperatures, yet starting a diesel engine in very cold weather still poses considerable difficulties.
Modern diesel engines for propeller-driven aircraft are manufactured by Thielert Aircraft Engines and SMA.
Engines running on diesel also provide more torque and are less likely to stall as they are controlled by a mechanical or electronic governor.
Petroleum-derived diesel is composed of about 75 percent saturated hydrocarbons (primarily paraffins including n, iso, and cycloparaffins), and 25 percent aromatic hydrocarbons (including naphthalenes and alkylbenzenes).
There has been much discussion and misinformation about algae in diesel fuel.
The term DERV ("diesel engined road vehicle") is used in the UK as a synonym for unmarked road diesel fuel.
Use of biodiesel also results in substantial reductions of unburned hydrocarbons, carbon monoxide, and particulate matter compared to either gasoline or petrodiesel.
On August 23, 2006, the British-based earthmoving machine manufacturer JCB raced the specially designed JCB Dieselmax car at 563.4 km/h (350.1 mph).
Chemically, most biodiesel consists of alkyl (usually methyl) esters instead of the alkenes and aromatic hydrocarbons of petroleum derived diesel.
The use of biodiesel blended diesel fuels in fractions up to 99 percent result in substantial emission reductions.
The density of petroleum diesel is about 0.85 kg/l (7.09 lbs/gallon(us)), about 18 percent more than petrol (gasoline), which has a density of about 0.72 kg/l (6.01 lbs/gallon(us)).
Poor quality (high sulfur) diesel fuel has been used as a palladium extraction agent for the liquid-liquid extraction of this metal from nitric acid mixtures.
The exhaust emissions of particulate matter from biodiesel have been found to be 30 percent lower than overall particulate matter emissions from petrodiesel.
Diesel-electric locomotives are used predominantly on most railroads worldwide, except in areas such as a high percentage of the European continent where overhead electrification permits use of electric locomotives.
Synthetic diesel may also be produced out of natural gas in the gas-to-liquid (GTL) process or out of coal in the coal-to-liquid (CTL) process.
At least one study has observed that short-term exposure to diesel exhaust does not result in adverse extra-pulmonary effects, effects that are often correlated with an increase in cardiovascular disease.
Diesel combustion exhaust is a major source of atmospheric soot and fine particles, constituting a portion of air pollutants implicated in human heart and lung damage.
In 1931, Dave Evans drove his Cummins Diesel Special to a nonstop finish in the Indianapolis 500, the first time a car had completed the race without a pit stop.
Other states, such as North Carolina, tax biodiesel (in any blended configuration) the same as petrodiesel, although they have introduced new incentives to producers and users of all biofuels.
Another rare disadvantage of diesel engines compared to petrol/gasoline engines is the possibility of runaway failure.
After winning the 12 Hours of Sebring in 2006 with the diesel-powered R10 TDI LMP, Audi won the 24 Hours of Le Mans, too.
Their greater economy is due to the higher energy per-liter content of diesel fuel and the intrinsic efficiency of the diesel engine.
