Gosh these two are a right pair
I'm not moving any goal posts , if you actually read properly the previous posts you will see the huge fees I talk about are for submission for approval .
It's a financial profit desicion , pay a huge fee to submit a sample for testing to gain a manufacturer approval spec .
Upon approval the oil is mass produced with regular checks to maintain approval .
This approved oil is usually marketed at a higher price , now like I said , only the big players can afford to do this .
Smaller players who produce a like oil
( Tesco , Asda , Halfrauds etc ) that meets or exceeds the requirements of 504.00 507.00
will market their oil usually at a lower price.
Halfrauds do make me laugh at £42.99 for 5 L of non approved .
So profits -
approved , sell high but the huge approval submission fee eats into that profit .
Non approved - meets or exceeds the requirements of 504.00 507.00 , sell low , but have no approval fee eating into that profit .
That's why with gearbox oils there are very few with any manufacturer specs because of low volume of sales compared to engine oil thus profit . Many VAG have this stupid life fluid rubbish about their gearbox oil so the gearbox oil is easiest to find at the main stealers at an extortionate price when a like product from the likes of Fuchs will come under Fuchs recommendations , believe me just because it won't be approved you won't get an inferior gearbox oil from them .
So comparing a like product non approved V approved we don't know the difference unless someone commissions a labritory analysis which I'm kindly informed is around £500 .
I don't know if this is comparing both as new and or used oil analysis to give the fullest picture .
To prevent inferior oil products being sold we have VLS
