What is BG MOA? Why experts choose fuel additives?

Understanding BG Advanced Formula MOA®

What It Does

BG Advanced Formula MOA® is engineered to protect engine components and enhance the performance of various brands of engine oil. It’s a multi-functional product that does the following:

  • Keeps piston rings from sticking.
  • Stabilizes oil viscosity.
  • Prevents increased exhaust emissions.
  • Reduces engine wear.
  • Prevents sludge and varnish build-up.
  • Resists evaporative oil loss.

Key Specifications

Some of the product’s notable specifications, tested under various ASTM methods, include:

  • API Gravity: 32.5
  • Specific Gravity: 0.8630
  • Flash Point: 179°C
  • Viscosity at different temperatures
  • Viscosity Index: 145
  • Pour Point: –32°C
  • Color: Brown

These specifications indicate a high-quality product that maintains stability under various conditions, ensuring the oil’s effectiveness throughout its service life.

The Science Behind BG MOA

Role of Additives in Engine Oil

Engine oil isn’t just a lubricant; it’s a complex mixture of base oils and additives. These additives, usually making up 10-30% of the oil, are crucial for:

  • Reducing friction.
  • Protecting against corrosion.
  • Removing contaminants.
  • Preventing sludge build-up.
  • Keeping the engine cool.

BG MOA adds to this complexity by introducing friction modifiers, which enhance fuel economy and reduce wear and tear on engine components.

How BG MOA Works

BG MOA works by supplementing the existing additive package in engine oil. It introduces additional anti-wear agents, viscosity stabilizers, and detergents, thereby:

  • Enhancing the oil’s protective capabilities.
  • Extending the life of the oil.
  • Maintaining engine cleanliness and efficiency.

Usage Guidelines

For optimal results, BG MOA should be used as follows:

  • Add 6 oz. for 3–4 quarts of engine oil.
  • Add 11 oz. for 4–6 quarts of engine oil.
  • Add 22 oz. for 7–10 quarts of engine oil.

It can be added to the crankcase anytime the oil level is low, but caution is advised not to overfill.


Licensed mechanics that are BG certified partners (Gary’s Automotive) are best recommended. If you choose a certified partner you could qualify for “engine for life” warranty protection if you receive a can of BG MOA at every recommended oil change.

The Debate: To Use or Not to Use Additives?

The Controversy

There’s an ongoing debate about the necessity and effectiveness of aftermarket oil additives like BG MOA. While some argue that standard motor oils are sufficient, others believe that additives like BG MOA can offer additional benefits, especially for older or high-mileage vehicles.

Our expert opinion? BG MOA works. It’s not a miracle worker though, it won’t turn a neglected engine into a work of art. If you care for your engine and want to keep it running at peak performance for as long as possible, it will help with that.

Factors to Consider

When deciding whether to use BG MOA, consider:

  • Warranty Implications: Check if adding an aftermarket product like BG MOA affects your vehicle’s warranty.
  • Engine Age and Mileage: Older engines might benefit more from additives due to increased wear and tear.

Conclusion: Balancing Benefits and Risks

BG Advanced Formula MOA® offers several benefits, including enhanced engine protection and extended oil life. However, its usage should be balanced with considerations like warranty implications and the specific needs of your vehicle. Always consult with a professional or refer to your vehicle’s manual before using any additive.

In summary, while BG MOA is a product with potential benefits, its use should be a well-informed decision, tailored to individual circumstances. Regular oil changes with high-quality oil are still the foundation of good engine health. BG MOA can be a supplement to this regime, but not a substitute for regular maintenance.
