Sean,

I have just come back from a day with Forte at their tech base in Coventry, organised by my Forte rep just to keep his customer parc up to date with contamination issues on modern motors, they do a demo with a bearing loading machine that tests lubricating qualities of various products, I have had my Forte rep out with same machine to assess the quality of oils I use, Quantum is the brand across all viscosities that only came close to the lubrication qualities of forte flush, Dexos 2,Ford XR come nowhere near !
