Synthetic oils are more resistant to oxydation and acids, increasing service life. Some users have started monitoring the quality of of their oils as they are used so that they are only replaced when necessary.

A petroleum product's "cloud point" is the temperature at which solids become visible in petroleum products. Synthetic oils have a lower cloud point than conventional oils making them suitable for use in severe cold.

Synthetic oils reduce friction more than conventional oils. This improves fuel economy and power while reducing part wear.

Synthetic oils are also more resistant to burning, lowering oil use and engine soot. Many high-performance and low emissions engines now require synthetic oil to ensure engine sensors stay clean.


Can I Use Synthetic Oil In Motorcycles Or Other Equipment With Wet Clutches?

Yes. Early synthetic oils would reduce friction to a point that these wet clutches wouldn't engage. Newer motorcycle-specific oils let these clutches work normally while providing the performance expected from synthetics. Friction modifiers are available to make gear oils compatible with limited slip and locking differentials.


Can I Use Synthetic Oil In An Older Engine?

Yes. Exposure to oil causes rubber gaskets to swell and remain flexible. Early synthetic oils were less effective causing leaks in engines; newer oils have additives that allow them to maintain or surpass the seal preservation qualities of conventional oil.


What Do I Need To Do To Switch To A Synthetic Oil?

Conventional oils can be replaced by synthetic oils that have a similar weight and service classification. Synthetic and conventional oils can be mixed, but the life of the oil won't be longer than straight conventional oil. While it is possible to extend oil life past manufacturer's specifications with careful monitoring, oil filter life will not be extended.
