Does diesel give more mileage than petrol ? Report Abuse. The reason diesels give better mileage is that less of the energy in the fuel is turned into heat which has to be got rid of via its cooling system,it revs a lot slower and the fuel can be metered a lot more accurately as it does not have to be mixed with air before it injected into the combustion chamber.o, you get more mechanical work from equal amount of fuel. Diesel engine gets more power from the same amount of fuel than it petrol counterpart. It means you have better mileage. Their notorious loudness is not an issue any more, modern diesels are almost equally quiet as petrol cars.

2014 Chevrolet Cruze diesel review: 50 mpg, 700 miles between fill-ups from a decent compact Sexy it isn’t, useful it is. The Chevrolet Cruze 2.0TD is your basic, well-made compact sedan that comes with a diesel engine. The Cruze turbodiesel gets 50 mpg on the highway and that translates to 700 miles between fill-ups. A 12,000 miles-a-year Cruze diesel might wind up refueling twice a month instead of three times with a gas engine.

Diesel Fuel and Gasoline Costs Gasoline is taxed at 18.4 cents per gallon, and diesel at 24.4 cents per gallon. That’s been true for years and explains why diesel has sold for an average of 1.3 percent more than gasoline over the time period covered by the EIA’s figures.It does not explain why the spread has gotten so wide recently, however.or the most recent week, ending May 19, regular gasoline sold for a national average of $3.79 per gallon at the pump, while diesel was $4.50. The price spread reached a record 22.4 percent in favor of diesel during the week ending March 24, 2008.

Hydrolock Due to their higher compression ratios, diesel engines have a much smaller final combustion chamber volume, requiring much less liquid to hydrolock. Diesel engines also tend to have higher torque, rotating inertia, and stronger starter motors than gasoline engines. The result is that a diesel engine is more likely to suffer catastrophic damage.

- A similar sized diesel will easily get 18 MPG or better. This is part due to the chemical properties of diesel fuel and gasoline. Diesel has more potential energy in it than gas does, so it takes significantly less diesel fuel to get the same amount of released (useable) energy.Much longer engine life.his is part due to the chemical properties of diesel fuel and gasoline.

- With cleaner diesel fuel and new engine technologies, today's diesel cars are actually about as quiet, smooth and clean as their gasoline counterparts. Combined with more off-the-line oomph (more low-end torque) and greater fuel efficiency (by about 30 percent), the case for diesel has never been stronger.

Close encounter with rare 25-foot basking shark in Puget Sound: âI didnât really feel scared, just excitedâ Basking shark spotted in the Puget Sound near Edmonds. Basking shark spotted in the Puget Sound near Edmonds. PUGET SOUND — A local family’s fish tale is making headlines across the country after a rare sighting of a 25-foot basking shark. The shark swam right up to the family’s boat, so they turned off the motor and just watched. The family got the show of a lifetime. “I didn’t really feel scared, just excited,” said Grace Coale who spotted the basking shark.

Tips for Increasing Diesel Engine Performance Perform periodic upgrading to the parts of the diesel engine. Installation of cold air intake systems will provide higher performance rates. In order to increase the combustion rate of the engine, install cold air intake system such that the air that flows into the engine is cooler than the air inside it.

10 Reasons You Should Buy A Diesel Car The price premium over a gasoline car is lower than for a hybrid or electric car. Per figures from LMC Automotive, cars running on diesel cost $2,500 more than the cars with a gasoline internal combustion engine, on average. For a hybrid, the difference is $4,100. For a fully electric car, it’s $13,000.

Can jet fuel be used in diesel engine semi trucks and farm tractors? Yes, it can. Jet fuel has less lubricity than Diesel #2 but with an additive such as Lubribore or Stanadyne Lubricity enhancer, your injectors and HP pumps will be happy. Jet fuel also has less BTU's (heat energy) per unit than Diesel #2 meaning that you will feel less power at a given throttle position.est Answer: It is possible to do this, but it's not a good idea. Jet fuel-kerojet (kerosene) - has chemical properties such that it does not combust at the same temperature and pressure in a diesel engine than diesel fuel does.

Understanding Diesel Fuels But there are a few kinds of diesel fuel: Just as gasoline is rated by its octane, diesel fuel is rated by its cetane, which indicates how easy it is to ignite and how fast it burns. Diesel fuel is safer than gasoline because its vapors don’t explode or ignite as easily as gasoline vapors.

How Diesel Engines Work Diesel fuel evaporates more slowly because it is heavier. It contains more carbon atoms in longer chains than gasoline does (gasoline is typically C9H20, while diesel fuel is typically C14H30). It takes less refining to create diesel fuel, which is why it used to be cheaper than gasoline.

Consumer Reports finds small turbo engines don't deliver on fuel economy claims By now, we've tested many cars with these engines, and lots of competitors with traditional, naturally-aspirated powerplants, big and small. Generally, the turbocharged cars have slower acceleration and no better fuel economy than the models with bigger, conventional engines. Looking at EPA fuel-economy estimates (calculated based on laboratory tests), some of these cars' turbocharged engines seem to have an advantage.

- In fact particulate emissions from petrol cars are so low that they are not routinely measured. Emissions from Diesel Vehicles. Diesel fuel contains more energy per litre than petrol and coupled with the fact that diesel engines are more efficient than petrol engines, diesel cars are more efficient to run.
