With performance claims that synthetic oil is better than mineral-based oil, car owners today search for the best synthetic blend oil for cars on the market. Synthetic blends claim to reduce engine wear, improve gas mileage and increase horsepower. Some may be surprised to learn that this product has been around for more than 50 years. True, they continue to upgrade and improve blends to meet requirements of autos today, but historically synthetic oil has been around since World War II when the Germans used it on the eastern front because it didn't freeze like conventional oil in the harsh winter weather. This is because synthetic oil molecules are more uniform in size and shape. This quality also makes synthetic blends better able to withstand extreme engine temperatures. However, be sure to check your car's owner's manual to find what type of oil is best for your car and chose a multi-grade with the narrowest span of viscosity appropriate for the temperatures you are going to encounter.
