engine oil comparison

The most basic criterion for a car owner is to consider the engine's money-saving features. In this area, the diesel engine fares better. Gasoline engines use fuel and air to create combustion. The diesel engine, on the other hand, relies solely on air compression and can attain combustion all by itself, thus doing away with spark plugs and tune ups. This means that diesel types get better fuel economy because of their self-combustion abilities. The diesel fuel, because of its high fuel density, allows diesel-engine drivers to save twenty to thirty percent in fuel consumption. Furthermore, in terms of fuel price, the diesel fuel is cheaper compared to the gas fuel.

However, when pitted against each other for initial affordability, the gasoline engine easily wins. Diesel engines, by known fact, are much more expensive that the gasoline-run ones. This is probably so because of the diesel engine has a stronger torque power compared to that of a gasoline engine. The former has enough torque to haul heavy equipment and can very easily ascend steep terrains. Because the diesel engine was built to sustain added stress of higher compression and cylinder pressure, diesel engines have a longer road life compared to gasoline engines.

But the diesel engine is not without its quirks and shortcomings. Motorists find the diesel's noisy and rattling run very annoying. Gas engines are far more capable of giving a smooth and relaxed ride as they only vibrate. Gasoline engines perform better in terms of acceleration. Because diesel engines do not have their own spark plugs, it is more difficult to get these engines to start up. This is hard to especially during winter season where the cold weather slows down the rise and combustion of the diesel fuel. There are, however, turbo-diesel variants that are said to deliver quicker acceleration.
