Petrol engine vs diesel engine : Which is the best?

  Engines are all about revolutions, and they tend to reach their peak power - or fun point - at a higher number of revolutions. They provide the thrill of a wind-up; as the revs rise and you fang through the gears, speed is added. In theory, this makes them racier and more engaging. Diesel engines produce grunt in the form of torque at much lower revs. Many people have wondered what type of fuel will be best suited for their upcoming vehicle. Each has advantages and disadvantages. One of the most important decisions to make when purchasing a car is whether to go with a petrol or diesel engine. While there is no simple solution to this, the following points can assist you in making a decision. Cost: Cars with diesel engines are more expensive than those with petrol engines. The price difference between petrol and diesel car variants will be greater. This is because the registration fee for a diesel vehicle is higher than that of a petrol vehicle. Mileage: The mileage of a diesel en...

What causes engine oil degradation?

  Automotive engines are being engineered to be more dynamic, quicker, and powerful as technology advances. However, these advancements come with their collection of problems, the most serious of which is oil degradation. Many types of equipment failures may be caused by fluid deterioration. A lubricant in use is exposed to a variety of conditions that can degrade it. Here are some causes of engine oil degradation :  Oxidation: The reaction of oil molecules with oxygen molecules is known as oxidation. It may cause viscosity to rise. Also, there will be the formation of varnish, sludge, and sediment. Additive degradation and base oil breakdown are also possible outcomes. You will notice a rise in the acid number when an oil begins to oxidize. Furthermore, oxidation can cause rust and corrosion on the equipment. Thermal Breakdown: One of a lubricant's key problems is the thermal breakdown. The temperature of a lubricant is one of the most important things that one should conside...
