Diesel and Petrol carsDo you have a plan to buy a new car or any vehicle? Before getting one just think which engine you are going to choose, either a diesel engine or a petrol/gasoline engine? Both engines have their own pros and cons. Most of them may be unaware about those things.

These are the most listed pros and cons of diesel engine and powered vehicles ever, but still a lot of people are loving diesel engines and vehicles. But increasing fuel price and most of the time equal to the price of petrol or gasoline removes all these fuel economy related advantages. Most of the trucks, industries and factories using this fuel in high amount making this one more demand wrapped fuel. Most of them refusing to buy a diesel car because it is heavier, more smoke producing, funny smelling, noisier with vibration and costlier than petrol powered ones.

Getting confused with the selection of diesel or petrol engine still. I may suggest a diesel vehicle only if some one ask with me. Because even if you purchased a low cost petrol car or vehicle, within one year itself you may have to spend too much money for fuel and other terms of work to make your petrol car well stable. So why cant you buy a new and little more costly diesel car which is economically friendly too with less pollution. All automobile giants still preferring a diesel engine for their latest models including the Volkswagen rolled out the Touareg V10 TD and Chrysler Jeep Liberty powered by a diesel engine.
