Ash content corrolations to Pre-Ignition

Vex, I read a few more articles about preignition on high performance outboard and air cooled aircraft engines. They only promote Ashless Oils.

It seems like Valvoline makes an ashless oil that may be a good rotary oil.

VR1 Racing Formula SAE 20W-50 (Turbo Approved) Motor Oil (other weights also).

Key features Valvoline VV211
High public presentation and shelter in spite of today's engines that go at high-pitched RPM
New ashless anti-wear additives combined by the side of ZDDP bring home the bacon most remote endure shelter
Enhanced anti-foam scheme helps secure the instrument regular for the time of uttermost emphasise
Enhanced additives preserve fronting high-temperature deposits with regard to a dry cleaner weapon
Friction modifiers facilitate gain h.p. yield
