> Quaker State 10W30 Defy, API SL synthetic blend (lab tested 2012)
> NOTE: An API SL rating is for 2004 and older automotive engines. This

> Silicon = 3 ppm (anti-foaming agent in new oil, but in used oil, certain
> gasket materials and dirt can also add to this number)
> Boron = 170 ppm (detergent/dispersant, anti-deposit buildup/anti-sludge)
> Magnesium = 8 ppm (detergent/dispersant, anti-deposit buildup/anti-sludge)
> Calcium = 2652 ppm (detergent/dispersant, anti-deposit 
> buildup/anti-sludge)
> Barium = 0 ppm (detergent/dispersant, anti-deposit buildup/anti-sludge)
> Total detergent/dispersant (anti-deposit buildup/anti-sludge) = 2830 ppm
> Zinc = 1221 ppm (anti-wear)
> Phos = 955 ppm (anti-wear)
> Moly = 99 ppm (anti-wear)
> Total anti-wear = 2275 ppm
> Potassium = 4 ppm (anti-freeze corrosion inhibitor)
> Sodium = 0 ppm (anti-freeze corrosion inhibitor)
> TBN = 6.5 (Total Base Number is an acid neutralizer to prevent corrosion.
> Most gasoline engine motor oils start with TBN around 8 or 9. And in use,
> this becomes depleted over time as mileage accumulates)
> Viscosity (cSt at 100*C) = 11.7 (cSt range for SAE 30 is 9.3 to 12.4) And
> cSt (centistokes) in general terms, represents an oil's thickness
>
> It looks like the zinc is 1221 which seems to be pretty good, especially 
> for
> the price! What do you guys think?
