The Great Diesel Vs Petrol Car Argument

So you are presently considering buying a new car, with the current economic climate all the signs are that you should consider a diesel engine for its fuel cost. What about the price of buying them, aren't petrol driven cars are so much cheaper in the long run? There seems to be a lot of confusion on the subject with many arguments both for and against both types. At the end of the day it comes down to what you are looking to gain when considering your next engine.Technological developments, especially with diesel engines mean that they are nowadays just as powerful and explosive out of the blocks and as powerful as most of their petrol cousins. Performance should not, therefore, be a real issue unless you are looking at very speedy models.Where diesel engines are more beneficial is in relation to green issues, fuel consumption and economy. They have a higher compression ratio and burn fuel more efficiently and diesel is still cheaper to purchase. The additional high cost of purchasing a diesel car however, may deter many customers though. Although the fuel savings are a bonus it will take several years before you see any realistic savings when you purchase a diesel car.If you have environmental concerns, then diesel cars make more sense. They produce less CO2 and their greater efficiency mean they use about 25% less fuel than conventional petrol cars, as well as generating less exhaust heat too.If you start buying diesel engines and continue to do so, then ultimately over a lifetime you will save money but the economics of the two engines mean that petrol is a better buy in the short term but over a longer period diesel will prove more economical.

Diesel vs Petrol Generators, Which Fuel Is Best

Petrol generators and diesel generators are the most common generator types available these days, but which fuel is best? Here we'll be looking at the pros and cons of petrol generators as well as diesel choices to help you decide on the right fuel and generator type for your needs.Petrol Generators

These generators use an extremely accessible fuel source which you can buy at any petrol station (of course!). If you already use these generators you'll know that this is a simple fact but one which should not be overlooked. The convenience of using these types of generators should not be underestimated.These generators also use a high quality fuel which performs well and very reliably, unfortunately it's quality makes it a little pricey. Most of us are already aware of the rising petrol prices these days.

There are a few other disadvantages to petrol generators too. Petrol is highly flammable which makes it dangerous if you intend to stockpile it for future use (it also has a short 12 month shelf-life so you'll need to watch out for that too). It is not the most efficient of fuels either. These generators perform well, but do gulp down a lot of fuel.Diesel Generators

Unlike petrol generators, diesel generators use a relatively non-flammable fuel, making it safer to store. Diesel is just as easy to get hold as fuel for petrol generators but it also has a slightly longer shelf-life (18-24 months).Diesel generators have notoriously long lives. 20,000 hour lives are relatively normal for liquid-cooled 1800 RPM engines. They are steady and reliable, taking long periods of use very well. They are also cheaper to run than the generators discussed above as diesel is less expensive than petrol.On the downside, diesel generators tend to be much noisier, heavier, less portable, higher maintenance and the initial cost of the equipment itself can be more expensive than purchasing petrol generators.So Which is Best?Realistically, the answer is that it depends. There are pros and cons to both generators, the best fuel for you really depends on what you will be using your generator for and when and where you intend to use it. Petrol generators are much more convenient if you're looking for portability and performance, whilst diesel is better if you're looking for rugged, sturdy drive.Diesel has the edge in terms of price and shelf-life but this is reasonably marginal as prices fluctuate and the shelf-life difference only has a few months in it. It really just depends on the kind of generator you want to run.If your concern is environmental, neither generators are particularly good! Diesel emits NOx, CO2 and soot whilst petrol gives out HC and CO smog. Their production processes vary slightly, petrol takes more energy to produce, but really, in the end, it is a case of a rock and a hard place - you may want to check out propane gas if the environment is your area of concern!

Petrol or Diesel – the pros and cons

Most people who have been driving for some time have a preference for either diesel or petrol engines. Whilst diesel engines have tended to triumph over petrol engines for their fuel efficiency, petrol engines have offered a quieter and smoother drive. However engineering developments have meant that the latest diesel engines can now be considered on par with most petrol engines. Turbo chargers and common rail injection means that diesel cars start quicker and offer a more pleasant drive. And it is not just the engines that have been updated; diesel fuel has also been modified so that it is no longer as smelly or difficult to refuel with. And diesel fuel still offers more mileage for your money when compared to petroleum. So now the decision about whether to choose petrol or diesel engine for your next car might be a tricky one. Comparing the cost to buy and maintain is a good way to help make that decision easier. For example, the purchase price of a brand new diesel car will typically cost you more than a similar car with a petrol engine but you should be able to sell the car for more when the time comes.

Your motor insurance premiums is not necessarily dependant on whether you have a diesel or petrol car but as diesel cars cost a little more you will be insuring a more expensive vehicle, which could make a difference to the amount you pay. Both diesel and petrol engine cars should cost around the same amount to service, however diesel engines may require more oil changes than petrol, which will come at an extra cost. You should also consider the price of road tax, which is now based on official measures of CO2 emissions. Diesel engines are more fuel efficient and therefore they tend to produce less CO2 emissions which means you could pay less for road tax than you would for a petrol car. However, Diesel engines do tend to produce more toxic emissions, which are not so good for the environment. When starting your car diesel engines warm up faster then petrol, which means that if you make short journeys during which your engine has hardly any time to warm up, than a diesel would be better. But if you are spending more time driving around in traffic filled towns then a petrol car would suit your needs better. Fuel consumption for motorway driving is very similar for both petrol and diesel cars, so there is not much to difference between them in this case, but diesel cars are better for towing as they have more torque.

You should remember that petrol and diesel are not the only options available. You can also buy cars that are built as hybrids, which have been designed to have a small petrol or diesel engine as well as an electric motor. It is the electronics in the car, which can run off the electric motor dependant on how much power is required. At the moment Hybrids are cheaper to run than pure diesel or petrol engines but at present they are more expensive to buy. So the main choice is still between petrol and diesel engines and that is a tricky decision to make. Rochelle Martinez, Freelance Web Content Article Writer for three years.
