When To Buy Synthetic Oil

By Sally Delacruz


High-performance vehicle owners are very familiar with the need for lubrication strong enough to resist temperature extremes without breaking down. Made primarily from organic compounds and hydrocarbon derivatives, these laboratory-designed engine oils differ radically from standard petroleum products. Although many drivers are aware that there is an alternative, most have questions regarding when or even whether to buy synthetic oil.

When the German war effort was in danger of losing its oil supplies during World War II, a substitute was hastily developed to keep the machines moving. Human conflicts often speed the development of technology, and these products are one example of an unintended but positive outcome. Over seventy years later the same basic manufacturing principles are used to make a variety of lubricants, from pure synthetics to blended products.

Crude petroleum today is relatively abundant, but the price remains high due to increased world demand. Like many human improvements on nature, making a synthetic derivative can actually drive prices higher, as much double the cost of a routine oil change. In an era when personal income shows very little real growth each year, many commuters are already pushing their financial limits just buying gasoline.

Potential users assume that a lubricant not derived from crude oil does not present the same environmental hazards, but that is only true up to a point. While not actually a refined petroleum product, it still has certain properties of hydrocarbons, and can have a measurable impact on air quality levels. Even with these additional costs and less healthy by-products, synthetics are increasingly recommended by auto makers as better vehicle maintenance.

In the early days, advertising campaigns for these products stressed questionable claims regarding additives and performance. While that did little to curry public favor, the fact remains that the agencies were actually correct in their overall assessments. Because important internal atomic structures are modified during the manufacturing process, individual molecules become nearly equal in size, creating a superior lubricant.

Being more homogeneous in size cuts friction, resulting in increased horsepower, while reducing overall wear and tear. Not only does this extend the life of a car or truck, but it also decreases the amount of gasoline a vehicle uses over the years. These lubricants flow normally during the coldest days of winter, while fully protecting the engine if the weather and hard driving create extended high temperatures.

Artificial compounds have a greater resistance to oxidation and thermal degradation, both of which can transform clean oil into dark sludge. This makes the intervals between recommended changes about twice as long, compensating somewhat for a higher shelf-price. Special additives resist acidic erosion, and help maintain viscosity in nearly all situations, making them perfect for engines with tightly engineered tolerances.

Even when not specifically necessary, using these products can help a vehicle run better and longer. While it is advisable to heed the advice of the manufacturer regarding oil use, mixing synthetic and standard products will not cause damage to most engines. Having a cleaner running vehicle benefits everyone, and until the time comes when hydrocarbon-based lubricants are no longer needed, synthetics are an excellent choice.
