Synthetic Blend Oil Versus Synthetic Oil

Here is a quick compare between synthetic blend oil and fully synthetic motor oil.

Synthetic Oil

Synthetic oil is derived from refined crude oil that is chemically modified to produce a higher level base stock. Other raw materials such as methane, carbon monoxide, and carbon dioxide may also be used. The oil is termed synthetic because these natural ingredients are chemically recombined to yield synthesized-hydrocarbon molecular chains of more consistent size and shape than those found in even the highest-quality conventional motor oil. Compared to conventional motor oil, synthetic oil offers improved protection at low temperatures, enhanced high temperature durability, reduced oxidation, fewer contaminants, and reduced engine wear.

Synthetic Blend Oil

Synthetic blend oil is a blend of regular petroleum-based oil and synthetic oil. It is also sometimes called “semi-synthetic”. Synthetic-blend oils are designed to provide many of the benefits of fully synthetic oil, but at a reduced cost.  However, not all synthetic blends are created equal. Some only contain a small percentage of synthetic components resulting in products that sell for a premium relative to conventional oil but provide little or no benefit in terms of lubrication qualities. Unfortunately, most manufacturers do not publish the synthetic oil percentages on their product containers so it is difficult to perform product comparisons.
