Hi all,
I have a question regarding Penrite's 10 Tenths Racing line of oils. It's an Australian company so you might not be familiar with them but they claim to have a very stout high performance gasoline engine/racing style oil line.
Their additive pack is very strong with antiwear additives, and good levels of detergent. The 10w40 which I am considering has the following specs:
Viscosity, Kinematic, cSt at 40°C = 91
Viscosity, Kinematic, cSt at 100°C = 14.4
Viscosity Index = 164
Cold Cranking Viscosity, cP at -25°C = 6487
Ca content, Mass % = 0.296
Zinc, Mass % = 0.168 (1680ppm)
Boron, Mass % = 0.063 (630ppm)
Base Number = 9.8
HTHS = 4.49
There is Molybnedym as well, cannot recall how much. Interestingly they state that their "Full Zinc +" marketing means "Zinc level + Boron level combined as a total anti-wear package". I thought Boron was a detergent, not antiwear? Perhaps a different form? OBviously there is a ****tonne of zinc, this will probably kill catalysts quite rapidly despite their tech support telling me otherwise (probably depends on oil consumption).
They state the oil base stock is a PAO/Ester blend. My main query relates to the base stock quality. Their MSDS states the below ingredients:
1-Dodecene, trimer, hydrogenated 151006-62-1 55% - 70%
Synthetic Diester Proprietary 15% - 25%
Phosphorodithioic acid, O,O-di-C1-14-alkyl esters, zinc salts (Zinc dialkyl dithiophosphate) < 1.3%
Phenol, 2,6-bis(1,1-dimethylethyl)- 128-39-2 < 0.7%
Calcium long-chain alkaryl sulphonate Proprietary < 0.7%
Alkaryl amine Proprietary < 0.7%
Zinc, bis(dipentylcarbamodithioato-S,S')-,(T-4) < 0.4%
I've done some rudimentary searches online but haven't turned up anything significant. Can someone tell me how good this base stock, which is predominantly PAO, appears to be?

They also have a 0w40 product which is interesting too, as 10w is a little thicker than I'd like (we get down to 0*C where i live) and BMW spec a 5W for my car, but then qualitfy this is for all regions, so I could probably swing a 10w here and be fine but who doesn't like better cold start protection?
Specs:
Viscosity, Kinematic, cSt at 40°C = 85
Viscosity, Kinematic, cSt at 100°C = 14.9
Viscosity Index = 185
Cold Cranking Viscosity, cP at -35°C = 6009
Ca content, Mass % = 0.296
Zinc, Mass % = 0.124 (1240ppm)
Boron, Mass % = 0.063 (630ppm)
Base Number = 9.8
HTHS = ?
This one is a little more old school in that there is no Molybdenum.
