Thank-you!

Definitely on the LIGHTER side for a 40-weight.

aquariuscsm · May 21, 2013

Definitely a "thin" 40 weight. I was thinking Syntec 10W30 was in 13 range for the vis. Would that be correct?

Edited-never mind,I found it via search. The 10W30 is 11.3

Thanks!

Is the NOACK spec' for the Castrol oil available anywhere?

Clevy · May 21, 2013

Interesting.
So going by this voa would German Castrol be better,or no?

CATERHAM · May 21, 2013

I do like the 1001 ppm of Phos', higher all other PCMO 0W-40s other than RL.

Because of the lower KV100 value of 12.95cSt the resulting VI is also lower at 165. With such a relatively low VI I hope the NOACK is lower than 9%, but I doubt it.

I don't think there is much between these two oils.
Same VI although the 0W-40 should be slightly heavier but under 5% I'd say.
The 0W-40 definitely has more phos' which I like.

Do we know the NOACK of GC?

Agreed. I'm actually surprised that Castrol bothers to keep both the 0w-30 and the 0w-40 on the market right now. They're redundant. Alas, it's too much to ask for logic from oil companies sometimes.

Marketing is one reason.
Of course the BC 0W-40 is an SN oil and GC has never been upgraded to SM let alone SN.

BTW, with all the research that has been done on GC at BITOG was the NOACK spec' ever determined?

For comparison / convenience, here's the VOA on Mobil 1 0W-40:

Well, you know very well that the reason GC is still at API SL is due to the API additive limits which are stricter for Xw-30 grades.

My point was, why not terminate GC now that BC 0w-40 is available and meets all the same specs? What is the marketing reason for keeping GC alive?

Dparm, please accept a big brotherly HUG from me - Thanks!

I agree with you. Technically their is no reason.

Supposedly the GC NOACK is 11.28%:

CATERHAM · May 21, 2013

I suspect Edge 0W-40 will be similar and IIRC PU 5W-40 and 0W-40 are nominally around 11.5% as well.

So M1 0W-40 has 20 point higher VI and a NOACK under 9%.
To consider buying either BC, GC or PU it would have to be pretty cheap over the already inexpensive and readily available M1.

Not sure where they got that figure from since Castrol doesn't publish NOACK figures. Both GC as well as BC 0w-40 meet MB 229.5 spec, which means they must have NOACK no higher than 10%.

M1 0w-40 is at 8.8%.

PU 5w-40 SN is at 6.8%:

According to Castrol UK's Automotive Technical Manager, Edge and SLX are the same product. As such here are the specifications off the SLX data sheet plus what he provided in correspondence. Totally there are three products that I've come across, all either identical or very similar: Edge, Edge A3/B4, SLX Longtec.

NOACK 9.1%
MRV 22,800 @ -40C
HTHS 3.7 cst (from Edge tds)

I'm sticking with M1.

Fair enough. Thank you Caterham.
