Does Castrol Edge 10W30 contain sodium?

[rustypigeon]

My used oil analysis came up high in sodium when using Valvoline Synpower. Valvoline of course contains sodium, but my level was about 650ppm, which is higher than the amount Valvoline uses.

I did a leakdown test and could not find any evidence of a headgasket leak. I did a coolant system pressure test and found no obvious leaks other than a tiny radiator leak that has existed for 20 years.

If Castrol Edge does not contain sodium, I would like to give it a try to see if my levels remain elevated.

Valvoline is the only major brand that uses sodium additives.

Sodium is a metal. It is not salt.

looks like they use either boron or sodium, but never both

well...

from the link posted above:

Sodium can be an additive in oil. Components such as Engines require to be lubricated in order to prolong their life. One of the most critical properties of an oil is its ability to suspend undesirable products from thermal and oxidative degradation. Detergents and Dispersants play a key role in keeping things in suspension. Detergents are metal salts of organic acids in the form of carbonate. Detergents contain reserve base that is designed to neutralize acids from forming salts. Common metals that can be used to make neutral or basic detergents are sodium, potassium, magnesium, calcium and barium.

Basically sodium is a metal and has nothing to do with this post. Thanks for adding nothing

The question I have is why do only a few major brands use sodium as an additive? It seems like most of them try to keep the amounts down, except for Valvoline.

Valvoline is loaded with it, yet they use little to no boron or moly. It seems strange that one company would go so far against the grain of what others are doing, I wonder if that's a good thing or not? I've always considered that a bad thing, maybe it isn't?

When I spoke to Brandon like 3 months ago on the phone; he said that they are using sodium and other additives that do the same things as Moly that are cheaper than moly. I believe that too. Moly isn't the be all or end all additive as I like boron in Quaker State Conventional and Motorcraft and Kendall oils
