What is synthetic gold, and what is it used for? the question relates to my vw beetle which I had serviced.?
Answers:
The artificial production of gold is the age-old dream of the alchemists. It is possible in particle accelerators or nuclear reactors. Since there is only one stable gold isotope, Au-197, nuclear reactions must create this isotope in order to produce usable gold.

Gold synthesis from Mercury
Gold obtained by mining has copper and silver as impurities. Gold of higher purity can be made through the photoneutron process:
Mercury198 + 6.8Mev gamma ray > 1neutron + Mercury197 (half-life 2.7 days > Gold 197)
These energy levels allow a more efficient neutron source than the Spallation Neutron Source.

Gold synthesis in an accelerator
Gold synthesis in a particle accelerator is possible in many ways. The Spallation Neutron Source has a liquid Mercury target that will be transmuted into Gold, Platinum and Iridium, which are lower in atomic number.

Gold synthesis in a nuclear reactor
In a nuclear reactor gold can be manufactured by irradiation of platinum or mercury. Since platinum is more expensive than gold, platinum is economically unsuitable as a raw material. Only the mercury isotope Hg-196, which occurs with a frequency of 0.15% in natural mercury, can be converted to gold by neutron capture, and following K+- decay into Au-197 with slow neutrons. Other mercury isotopes are converted when irradiated with slow neutrons into one another or formed mercury isotopes, which beta decay into thallium. Using fast neutrons, the mercury isotope Hg-198, which is contained to 9.97% in natural mercury, can be converted by splitting off a neutron and becoming Hg-197, which then disintegrates to stable gold. This reaction, however, possesses a smaller activation cross-section and is feasible only with un-moderated reactors. It is also possible to eject several neutrons with very high energy into the other mercury isotopes in order to get the Hg-197. However such high-energy neutrons can be produced only by particle accelerators.
its oil also known as black gold
I's a synthetic motor oil.
Its the engine oil.
Synthetic engine oil, and rather than being called premium or extra, or some other meaningless name, they called it Gold
Motor oil.
It's synthetic engine oil.
Its a fully synthetic oil that conforms to Audi and Volkswagen spec.It was obviously a main agent as you were over charged.Mick
