Here are my VOA's for the Castrol & Pennzoil 507.00 spec oils. www.bobistheoilguy.com/forums/ubbthreads.php?ubb=showflat&Number=2824211#Post2824211

+1 I'm a fan of the PU Euro L. I posted a Blackstone report in the VOA forum.

I know you are looking for MB 229.51 in a 5w40... but isn't that spec a low SAPS oil? I was under the impression that no 5w40 met that.

Blackstone Labs 11/30/12 Castrol SLX Professional LL03 5w-30 Boron: 1 Silicon: 1 Sodium: 3 Calcium: 1700 Magnesium: 1 Phosphorus: 803 Zinc: 901 SUS Viscosity @ 210F: 64.7 cSt Viscosity @ 100C: 11.54 Flashpoint: 430F TBN: 5.4

Blackstone Labs 11/30/12 Pennzoil Ultra Euro L 5w-30 Boron: 70 Silicon: 3 Sodium: 1 Calcium: 1676 Magnesium: 8 Phosphorus: 634 Zinc: 723 SUS Viscosity @ 210F: 65.4 cSt Viscosity @ 100C: 11.71 Flashpoint: 460F TBN: 5.6

That's what I'm thinking. The additive pack isn't that much different. Higher flash must be the base.

I can get 6qts of the PU via Amazon Prime for $56. I didn't think about the newer-gen base stocks. Good call. I've used SOPUS products for years, and based on these results, it looks like there is no need to change. Thanks for the warm welcome!

Hello, All! I'm a new BITOG member, but a longtime visitor. I bought a new VW Golf TDI and wanted to see how Pennzoil stacked up to the dealer-carried Castrol. These are both VW 504/507 spec oils. So... here are my Blackstone VOA reports. Please pick them apart, and let me know what you think...
