    1. Customer Support - Advisor says:

      Hello Paul Brown,

      We would like to thank you from the bottom of our hearts for your comment and your interest in our gear oil additive comparison. Your support is important to us!

      No, the gear oil additive is primarily designed for manual transmissions and should not be used in automatic transmissions. It is recommended to use products specifically designed for automatic transmissions as they have the necessary additives to optimize the function and performance of the transmission. Please check the product description and application recommendations to ensure you are using the correct product for your transmission system.

      From the support department to Friedrichsdorf - greetings!

    1. Customer Support - Advisor says:

      Hello Amit,

      Your feedback on our gear oil additive test & comparison is a source of joy for us. Thank you for helping us to develop further!

      A transmission oil additive is designed to improve the performance of your transmission. It is a special formula added to gear oil to improve its lubricating properties. The additive forms a protective layer on the transmission parts, reducing friction and wear. It can also increase the transmission oil's resistance to oxidation, corrosion and deposits. Overall, a transmission oil additive can help extend the life of your transmission and improve shifting.

      Best regards from the customer care team to Hoyerswerda.

    When should a gear oil additive be used?

    1. Customer Support - Advisor says:

      Hello Anton,

      We really appreciate your comment and your interest in our gear oil additive test & comparison. Thank you!

      There are various reasons why one should use a transmission oil additive, such as to increase transmission life, reduce wear and improve shifting performance. However, a gear oil additive should only be used if it is compatible with the gear oil recommended by the manufacturer.

      Best regards to Sankt Wendel.
