Blackstone: OHN: This was a clean and dry, unused gasoline-use engine oil with a viscosity the 5W/30 range.
The additives are a typical group used in several brands of oil. Calcium is a detergent/dispersant
additive, while phosphorus and zinc and anti-wear additives. The TBN read 13.4, quite high. Is this oil
fit for use? Sure is! It should do great in your engine(s).

Looks very nice. High zinc with lower phos. Plenty of detergent, so I suspect this is suitable for street use. Good flash, some moly and a great TBN. Be interesting to compare to the regular RP 5w30.
