Silverline Oil - anyone heard of/used it?

[HFB]

Was chatting to a chap on Wednesday whilst having a play over at Lydden Hill   s8) s8)  

He bought a franchise and sells a range of high performance engine oil products that he says are supposedly way better than fully synth oils.

Not cheap at £75 for 5L (can get Fuchs 5W40 for about £38 with discount codes) but if it does as he says and can withstand greater pressures and prevent greater wear on the engine, then it might be worth considering.

Anyone ever heard of it (I hadn't) or know much about it to comment?
