Default Re: Engine(oil) Additives(treatments)

Hopefully the "chemist" (Gold2006) will clarify the difference but from what I've read (do we trust the Internet?), I'll stick to full synthetic in all me cars.

What is the difference between synthetic oil and synthetic blend oil?

A fully synthetic oil is made to provide a much purer base oil, with less waxes and with a uniform ideal particle size to help increase the oils viscosity level. Added to this ideal base oil is a combination of more technically sophisticated additives than are used with the conventional oils.

Semi-synthetic oils are an alternative to buying a pure synthetic oil. These combine a certain quantity of synthetic base oil with a conventional base oil in order to provide a high quality oil which can be used to gain some of the protection benefits of a fully synthetic for slightly older vehicles. However semi-synthetic engine oils do not typically include all the synthetic oil's advanced additives.


BTW: Gold2006 was last on the forum Yesterday so hopefully he will see this thread. I'll drop him a PM.
