I have heard that it is better to make your own SYNTHETIC BLEND of MOTOR OIL, rather then buying one that has already been blended. Is this so?
Yes! You can take conventional motor oil and mix it with a full synthetic motor oil. The reason why it is better to make your own is that the blends on the market do not tell you what percentage of the product is synthetic. To qualify as a synthetic blend the oil has to have a very small amount of synthetic in it. Synthetic oils are compatible with conventional motor oils. Making your own allows you to put in as much synthetic as you want!
