Royal Purple 10W30 HPS

[DragRace]

All samples were taken from brand new, thoroughly shaken bottles of oil. And all tests were performed at ALS Tribology, formerly Staveley Labs, in Sparks, Nevada.

Royal Purple 10W30 HPS (High Performance Street)
Silicon = 7 ppm (anti-foaming agent in new oil, but in used oil, certain gasket materials and dirt can also add to this number)
Boron = dispersant)
Magnesium = 46 ppm (detergent/dispersant)
Calcium = 3626 ppm (detergent/dispersant)
Barium = dispersant)
Total detergent/dispersant = 3676 ppm
Zinc = 1774 ppm (anti-wear)
Phos = 1347 ppm (anti-wear)
Moly = 189 ppm (anti-wear)
Total anti-wear = 3310 ppm
Potassium = 11 ppm (anti-freeze inhibitor)
Sodium = 2 ppm (anti-freeze inhibitor)
TBN = 10.2 (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) = 11.3 (cSt range for SAE 30 is 9.3 to 12.4) And cSt (centistokes) in general terms, represents an oil’s thickness.

Looks like a great muscle car oil.

Friend of mine runs it in his 500 HP 2003 cobra.

I wish auto parts chains would sell this stuff!

Good balance for long drain (ALA Ams) - too much CA for short drain racing though.

I think this oil became a bargain.
