I did NOT say they are ALL the same!!!
The reason it's better to use a better known supplier is to make sure you really ARE getting what it says on the tin.
I suspect there are prob only a small number of companies that actually refine these oils - many others just blend them and even more just repackage them.
I know a bloke who worked for Duckhams - he was an engineer there and he said that it was incredible the companies they used to supply with oil. These days he works with a slightly thicker oil - bitumen!!!
