RUP in 5w40 is still available tho, but I have no idea about the SAPS or HTHS on this oil.
RUP is same .8 % SAPS as REP. I mentioned HTHS and it's specced by the manufacturer.
Just see the links below. RUP is virtually same formulation as REP except for slightly thicker
base oils. While REP is at the thicker end of 5W-30, RUP is at the thinner end of 5W-40.
Honestly, I doubt you'll notice the difference.
Both BMW LL-04, MB 229.51 and probably also Porsche C40 and VW 511 010 mandate
fuel savings requirements that can only be accomplished by using not too thick base oils.
Generally all MB 229.5/51 and BMW LL-04 approved PCMOs are fairly close in viscosity
whether they're 5W-30 or 0W/5W-40. A thinner 0/5W-30 at 9.5 cSt and 3.0 mPas wouldn't
meet the requirements, as well as a thicker 5W-40 at 15.7 cSt (100°C) and 4.5 mPas HTHS
very most likely wouldn't.
....... RUP is very similar and just a tad thicker. ......
....... (HTHS
REP is 3.7 and
RUP is 3.9 mPas. .......

Where did I say it was a boutique oil? It is not, what it is is a mid tier oil depending on "Made in Germany" advertising.
Did you read the other thread on this oil where there were significant differences between batches?
I said..
I seem to have got you wrong then. I have read that discussion you refer to some time ago.
I doubt batches do vary. Actually cheap consumer oil analysises do vary. You cannot assess
viscosities based on imprecise analysises. We use to see the same with Blackstone. If I do
remember correctly that discussion refered to a German forum where expertise is rare. The
only things worth reading on that forum are VOAs and UOAs, but you need to draw your
own conclusions from them.
That said, I don't think Ravenol are going the 'Made in Germany' route just like LM. Their
data sheets makes no mention of it. It's just on the bottle. I see lots of US made products
saying 'proudly made in America'. Nothing wrong with that. I almost only buy European and
American stuff anyway, in particular when it comes to cars. Bad enough my smartphone is
assembled in China. Wish it was made in Cupertino.
