Synthetic oils

The above post is a good example of what synthetics are about. Quality synthetics and quality conventional oils will do what they are designed for. But synthetics will provide an extra measure of protection with HP, mileage and extended life of the engine as a bonus even if nothing compromises the protection the oil provides, like parts failure, pressure loss, etc. Aircraft are a perfect example of where that "extra" protection/insurance/durability is needed. Should there be a problem at 20,000 feet, one can't simply pull over and call a tow truck.

In a passenger or race car application, if you want an extra measure of "insurance" with the additional benefits mentioned, quality synthetics are the way to go to protect your investment. Insurance-wise - "standard coverage" fulfills some peoples needs just fine while "full coverage" works well for others. It just depends on your needs.
