Penzoil 5-50 synthetic????

Saw this stuff at a local gas station recently. No mention of ACEA A3 on the bottle nor on their website. HTHS shows 4.29 yet the viscosity at 100C is thicker than Syntec with an HTHS of 4.5. So much for the Penzane molecule....what does it do exactly??? Is it like moly? Anyone use this grade of Penzoil???

Dr. T, I have not seen this oil being sold anywhere for a very long time. I called Pennzoil several months ago to ask if this oil was rated ACEA A3/B3 and they said it wasn't on the tech data sheet so the answer was no it didn't have the ACEA rating. I did notice the pour point of -50 C which I think is great for a 50 wt motor oil. The other specs are OK. But I still wonder why it isn't rated ACEA A3/B3. Do any large chains of auto parts stores still sell the Pennzoil 5W-50? [ June 11, 2003, 09:38 AM: Message edited by: Sin City ]
