I've been put onto this product - Vivax Superstar - by my ace 'old school' proper mechanic John at Old Forge Motors, Harrogate and I'm just wondering if anyone has used it or even come across the company High Speed Lubricants? It claims to reduce friction and prolong engine life (not the only one to do so.....). John swears by it despite years of sceptism over various snake oils. Here's their website if you want to know more: www.highspeed.co.uk Unless I get negative feedback I might just give it a go at £5.99 per litre/one litre per oil change.
