Consider synthetic motor oils
It is important to remember when considering synthetic motor oils that the oils sold at your local auto parts store as synthetic are actually what the author of the Motor Oil Bible calls “pseudo-synthetic basestocks.” These are petroleum basestocks that have been put through a super intensive refining process called “hydrocracking.” This involves changing the molecular structure of the basestock, resulting in a basestock which has many of the qualities of a synthetic basestock, so much so that motor oils made in this way can be legally sold as “synthetic.” While these outperform traditional petroleum oils, this is something that must be weighed when buying “synthetic” motor oil. You may want to spend the extra money to get a truly synthetic motor oil.
