"Controlled phosphorous and low chlorine" additive

[vinu_neuro]

Molakule,

For the newer Euro oils, Castrol mentions that it's using "controlled phosphorous and low chlorine additive technology," that they're saying is better for cats. and oxygen sensors. Is this something that only Castrol is using and or does everyone use this and Castrol decided to market it. And is it effective in that goal?

What about Dogs?!?!

Controlled phosphorus simply means that they are using a low volativity ZDDP.

The chlorine is a esterified chlorine but I wouldn't use it in any of my formulations.

In an oil burner, would controlled phos end up being as bad as something like what's in M1 0W-40 (assuming they don't also use it)?

I'll answer my own question. It seems catalyst P exposure through oil consumption and volatization are completely different. It seems low-volatility just refers to chemical volatility (eg. normal service with no oil consumption).
