Today in a car shop I heard a conversation between a seller and a buyer, the seller offered him polyalphaolefin oils with a viscosity of 0W20, when I heard their cost, of course I was very amazed, what kind of golden oils are they?
Well, you need to start with the fact that it is fully synthetic Engine oil 0w20 they have very specific characteristics and minimum viscosity, it is too liquid for most old cars, so this oil is used in new Japanese and American cars or racing cars. These vehicles have a special engine design that requires high fluidity lubrication due to the compression and torque values. High quality 0w-20 synthetic oil is generally formulated to protect engines even at peak loads. 0w-20 oil also improves fuel economy and even engine efficiency.
