That’s a very good oil, I’m using it myself right now.

It’s only SL rated because as a 30 grade oil it’s got too much zinc and phos to be classed higher under API, but it certainly passes all the SN quality tests according to Castrol. It runs about 1000 ppm zinc (ZDDP), which is about 200ppm more than your typical ILSAC oil.

It also carries ACEA A3/B4 with BMW LL-01, VW 502 / 505 and MB 229.5 which are very high quality OEM specs. The MB spec requires that Noack volatility is below 10%
It has HTHS = 3.6 cP and TBN is 10.2 from data sheets I have tracked down.

BTW the Australian PDS list the pour point as -45C

Not trying to give any grief but is it too much to ask posters to copy and paste a link?
Fair point.

I was on my phone using the WM app which doesn't allow sharing of that page, with a hot link, to a web page.

I tried but it didn't work plus I was heading out the door to run errands so I wanted to post just enough core info so people could find it.

I had no idea an A3/B4 existed in this weight.
As far as I know ACEA Sequence A3/B4 doesn't have a grade requirement, only a minimum HTHS.
