Specs on Castrol Syntec?

[G-MAN]

Has anyone ever seen a spec sheet on Castrol Syntec? It would be nice to compare this oil to other synthetics, but there is nothing on the Castrol web site about it except marketing BS.

I've got one. I had to email Castrol and get them to mail it to me though. The specs aren't too impressive IMO.

As has been mentioned earlier. The specs are for the most part the properties of the base. The additive package is also very important. But the real test for the oil is how does it hold up in terms of protecting your car and lasting. Many of these specs can't tell you that. I think to say this oil or that oil has "mpressive" spec sheets says very little. We know its a group III and we know that Castrol practically invented the word "scam" when it comes to truth in advertising (in my opinion)- Now thats "impressive"

XHVI, If you go to 3w.Maxima.Org and download their oil analysis spreadsheet, you can find the baseline data on the 10w-30 Syntec: boron, 25 ppm Ca, 1910 ppm Mg, 571 ppm P, 1175 ppm - very interesting, since this is a licensed formulation. So much for API enforcement Zn, 1261 ppm viscosity @ 100C, 10.2 TBN, 10.4 Unless you can get this for <$3.00/qt, I'd stick to Mobil 1 for an off the shelf synlube.

Which grade are you interested in? I have this for their 5w-30 from 2001: SL/CF VI 172 PP -38*F FP 455*F FRP 475*F HT/HS 3.00 Phos 900 Zinc 1000 CCS [email protected] -25*C Ash .9

Interesting CCS test temp. I thought SL/GF-3 5w oils were now tested at -30*C and 10w at -25*C. A CCS of 2400 is very misleading if you compare it to say Mobil 1 5w30, which is 3600 (but at -30*C).

Specs for Castrol Syntec SL/CF from 2001: 0w-30 5w-30 10w-30 5w-50 Specific Gravity 0.84 0.85 0.85 0.85 Viscosity @40 C 56 53 70 120 Viscosity @100 C 10.5 9.8 11.5 19.5 Viscosity @-25 C 2750 2400 2500 3050 High Shear Vis. 3.1 3.0 3.5 4.8 Viscosity Index 181 172 159 180 Flash Point 210 C 235 C 235 C 241 C Fire Point 221 C 246 C 246 C 249 C Pour Point -42 C -39 C -33 C -39 C Sulphated Ash 0.9 0.9 1.04 0.93 Zinc 0.10 0.10 0.11 0.11 Phosphorus % Wt. 0.09 0.09 0.09 0.09 Sulfur % Wt. .028 0.29 0.29 0.28 Please note that the low temperature viscosity is at -20 C for the 10w-30 and done at -30 C for the 0w-30. Castrol does not give a TBN. Also the 5w-50 is rated by the ACEA as A3/B3. I think the others are only A1/B1. If I can find the spec sheet for the 10w-40 I will post those numbers. I believe it is rated ACEA A3/B3 B4-98. [ November 20, 2002, 04:15 AM: Message edited by: NevadaDesert ]

It looks like I did not line up the specs properly. If you can read it I hope it will be of some use.

Yeah, I know. The J300 SAE viscosity standards have been out since June of last year and several companies still haven't updated their spec sheets.
