Just a bit of background. I'm looking at changing the oil on my new V6 Mazda6 and am going to follow Mazda's recommendation to use 5W-20. Having lurked for a while I've seen a couple of other 5W-20 VOAs and hadn't seen one on Valvoline's 5W-20.
The testing was done by Blackstone Labs
Aluminum 1
Lead 1
Boron 1
Silicon 2
Sodium 1
Calcium 1939
Magnesium 5
Phosphorus 798
Zinc 936
Barium 1
All other values are zero.
TBN 10.0
Flashpoint 435F
SUS Viscosity @210F 52.8
What is the viscosity conversion to cst?
Now I'm left with the dilema of which of the easily available oils to use: Motorcraft/Conoco, Pennzoil, Castrol, and Valvoline. I'd consider Mobil DriveClean if I can find it in one of the nearby cities.
