Gear Oil Additives And ATF Additives
Gear oil additives and automatic transmission fluid additives are formulated for different systems. The right choice starts with the lubricant and the transmission or differential, not just the word "gear" in the product name.
The Liqui Moly products in this collection include MoS2 Gear Oil Additive for specified manual gear and axle applications and a separate ATF Additive for specified automatic transmissions. Follow the additive maker's application instructions and the vehicle manufacturer's lubricant requirements.
Choosing A Transmission Or Differential Additive
Liqui Moly 2019 is not intended for automatic transmissions or wet clutch systems. The separate 20040 ATF formulation has its own fluid restrictions; match the product to the system before adding it.
An additive is mixed with the correct lubricant at the manufacturer's specified proportion. Consider the system's fluid capacity when choosing the amount to purchase.
Frequently Asked Questions (FAQ)
Can Liqui Moly 2019 be used in a limited-slip differential?
The manufacturer specifies its MoS2 Gear Oil Additive for differentials without a limited-slip function. A limited-slip axle may require its own approved lubricant and friction characteristics.
Is the 20040 ATF additive suitable for every automatic transmission?
Its manufacturer specifies automatic transmissions using Dexron II or Dexron III based fluid. Check the vehicle's required fluid and whether its manufacturer permits the additive before use.
Can an additive be used instead of changing old transmission fluid?
The additive is a supplement to the lubricant, not a replacement for a fluid change. Follow the vehicle's fluid type and service interval, then use an additive only if it is suitable for that system.
How much additive is needed?
The amount depends on the product and the system's fluid capacity. For example, Liqui Moly specifies one 50 g tube of 2019 for 1 to 2.5 liters of gear oil; use the instructions for the exact product and application.
Can the 2019 gear additive be mixed with synthetic oil?
Liqui Moly says its 2019 formulation is suitable for both mineral and synthetic gear oils. The gear system must also meet the product's application restrictions and the vehicle's lubricant requirements.
