Scottish Elises

Does anyone have any experience of using this?
It would seem to the the Valvoline equivalent of Mobil 1.
Asking as the rep has been trying to sell it to my Dad at a very good price

I have used valvoline for years, all types in differant engines
syn power 5-40 fully syn in the elise

its a very good oil , i know a few taxi drivers who swear by the product aswell
