This is slightly confusing but:
- "Advanced Lubrication" is High Performance Lubricants. These are the products developed by or under the guidance of Dr. Rudnick.
- "HPL Oil" is a private label product blended by Advanced Lubrication for another outfit to their spec.
Think of the red "HPL" as TGMO being blended by ExxonMobil. Just because Mobil blends it, doesn't mean it's Mobil 1.
