What does each oil additive chemical do?

[zerosoma]

Did a google search and didn't come up with much.

I'm wondering in those tests, when they show all the numbers, what does each chemical/additive do?

Like this VOA from some old Syntec I found :

Code:


Aluminum 0

Chromium 0

Iron 1

Copper 0

Lead 0

Tin 0

Molybdenum 2

Nickel 0

Manganese 0

Silver 0

Titanium 0

Potassium 0

Boron 1

Silicon 4

Sodium 5

Calcium 1053

Magnesium 926

Phosphorus 786

Zinc 918

Barium 0





SUS @ 210 70.7

Flashpoint 400 F

Fuel % 0.0

Antifreeze % 0.0

Water % 0.0

Insolubles % 0.0

TBN 10.8




I know Moly is a friction reducer and wear additive, but what do the rest do for your engine?

Thank you!

so this sample would indicate that the oil is good for cleaning and suspending deposits, and using the zinc for an anti-wear property?
