JP,
Consider what you have just said and step back. You are coming from a purely Motorsport angle, where cars will not sit and oil gets changed more frequently than may cat's litter tray. Can most people add an additional £60 to their budget per month? Not on the wages Ford pay me!
Others look for longer term on the road driving solutions. I once had the pleasure of having an indepth talk with a guy from Catsrol, as they had an office in the plant, due to the amount need for cutting the gears and filling the gearboxes. He took me through how Magnatec worked to Molecular level. Whilst most of it was lost on me I retained enough Physics and Chemistry to understand some of it. Whilst I can't comment on how other oils work exactly, the way in which he described the change in polarisation of some of the molecules to induce a magentic affect was truely interesting... and he was an engineer not a
PR guy. For after hearing that I would use Magnatec, as they say it is initial start up which causes most wear.
Just my tuppence
