Can I use Trans Tune in the gear oil of a GY6 scooter? [SOLVED] Asked by Josh L. In Georgia Can Trans Tune be used in gear oil for GY6 scooter engines? If so, can you recommend a ratio?
That’s a good question, Josh! Yes, you can use Trans Tune (or Sea Foam Motor Treatment) in your GY6 gear oil. Add 1 ounce of Trans Tune per quart of oil. Same ratio for Sea Foam Motor Treatment.
