PRO-2 Oil Treatment

Enhances motor oil to prevent oxidation, reduce oil consumption and restore power.

The Problem

A common issue with modern engines, as well as port fuel-injected systems predating GDI, is excessive consumption and heavy oxidative deposit formation. The advantage of lower viscosity oils and longer drain intervals make today’s engines more prone to increased wear and crankcase blow-by. This causes oil consumption that results in performance loss, diminished efficiency, and shorter engine component longevity.

The Solution

BARDAHL PRO® PRO-2 Oil Treatment is formulated for port fuel engine designs, as well as modern GDI engines operating with low viscosity full synthetic oils and extended drain intervals. Using proprietary ‘polar attraction’ technology, this formulation provides extra anti-wear and anti-friction protection that extends the effectiveness of the lubricant to protect the engine during long drain intervals and reduce oil consumption. Extra inhibitors help control oil oxidation, decrease deposit formation, and reduce bearing corrosion. This special solution minimizes wear and enhances overall engine performance while providing extra lubrication protection for city driving and heavy-duty operation.


  • Improves oil’s ability to control excessive oil consumption and protect components during extended drain intervals.
  • Restores compression and engine power to improve performance.
  • Boosts anti-wear, anti-friction, and extreme pressure performance of the oil.
  • Increases oxidation and corrosion protection of the oil.
  • Safe to use in gas or diesel engines and will not harm plastic or Teflon components.
  • Compatible with all types and grades of motor oil, including modern synthetics.


Add at each oil change and between oil changes as needed. Pour contents into the crankcase prior to filling with new oil. One bottle will treat up to 5 quarts of motor oil. For newer vehicles, use BARDAHL PRO® PRO-1 Oil Supplement (# 93400) to enhance performance. Dispose of any used or unused solution and container in accordance with local, state, and federal regulations.
