Oil Tech: Valvoline VR1 Racing "Ashless Additves"

[outrun]

Okay this again is a multi tier question. Here are my baseline assumption(s) & parameters:

A) Internal Combustion Engines, Gas Turbines, etc consume lubricants; rate variable

B) In our street engines, assuming a leak free system, that lubricant infiltrates and exits the combustion chamber causing what I will call "burning."

1)So even if I run a Redline, Amsoil ASL, Premium XXX, etc does the burnt off metal rich (Ca,Z,P) remnants of these leave deposits on the piston tops, exhaust valves, and possible intake valves?

**I know at least for weed-wackers etc you have "ashless oils" added proportionally to the fuel.

Is Valvolines forumulation truly ashless?? Could this be off use to engine that burns 1qt/3000 miles?? Does ashless imply a non ZDDP additive pack?

Thanks! Engine cleanliness is kicker PAO or not

it contains ashless additives, some of them are ashless, some are not.

Reminds me of the Fuchs GT1 0W20 oil which uses no ZDDP whatsoever!

Just as a PSA, VR1 comes in synthetics too. I was surprised to see it locally.

Not all ashless additives are ashless?

The statement does not exclude additives that may contain ash, only indicates that ~some~ of the additives are ashless. Someone could argue otherwise, but I don't think they are bound to the narrow interpretation.

Think they are referring to ASHLESS DISPERSANT oil additives. They use that tech in aviation oils all the time. No biggie. Just a dispersant.
