The best answer will be found in your Owners Manual!

Conventional Oil:

Conventional motor oil has been used in automobiles since since the first Model-T in 1908.  Back then conventional oil was as "crude", literally just like the name implies. Over the years, additives were added to conventional oil that are necessary to keep your car running at its best. These additives provide heat tolerance and breakdown resistance that engines need to run efficiently and economically. Conventional oil is inexpensive and some refer to as the less effective oil. Yet, this couldn't be farther from the truth. Although it is true conventional oil requires more frequent oil changes, it is also true that it is recommended by millions of auto service professionals around the world.

Generally speaking, conventional oil should be used for most older engines because it is denser. Older engines tend to have larger gaps between parts. And using a thicker oil will assist in preventing leaks.


Synthetic Oil:

Synthetic oil was created in a lab decades ago and has been prolonging motor oil life for a long time.  Most modern auto manufacturer's recommend synthetic oil for any of their new autos. Synthetic oil takes significantly longer to break down than traditional oils, so engines can go further without an oil change.  It better lubricates parts under extreme temperatures as conventional oil.  It also performs better in stop and go traffic.  It truly has more benefits than conventional oil, but these benefits sometimes come at a hefty price. Synthetic oils are more expensive.
 
If you have an older engine synthetic oil can seep through gaps and create leaks, and many mechanics have complained that older engines became much less efficient when using synthetic oil.
Why is it important to get your an oil change at regular intervals?
  • engine runs at optimum efficiency
  • proper grade can improve mpg by as much as 2%*
