      Made my 87 Porsche 924s like new
      By  RICHARD,  a  Verified Buyer  from  Ontario, California   on  April 30, 2026
      I thought the transaxle was going out on me. I inspected the clutch and it was fine. I switched to a better quality fluid, this stuff, and that did it. I think I was loosing horsepower or gears weren't engaging properly before. What a difference the proper fluid makes! Shifts are crisp, engagement is solid. I was missing out this entire time.
      Bottom Line
      Yes, I would recommend this to a friend.

      By  MICHAEL,  a  Verified Buyer  on  March 25, 2026
      I recently flushed out my transmission and differential and my car feels so light and smooth, the inertia from the driveline feels non existent. So much that I didn't realize I was actually speeding at one point while driving on the highway.
      Bottom Line
      Yes, I would recommend this to a friend.

      Hard shifting manual transmission
      By  RICHARD,  a  Verified Buyer  from  Florida   on  February 04, 2026
      My wife said she found her Miata 6 speed standard transmission was getting harder to shift. We learned years ago that Amsoil made are Harley Davidson transmissions much easier to shift, so I thought I would change her transmission fluid to Amsoil. Their experts said that they would send me the mix that was perfect for her Miata. Just like the Harleys, within a few miles the transmission became much smoother and downshifting is now a breeze. Since we started using Amsoil in our motorcycles we have done so ever since. Good stuff.
      Bottom Line
      Yes, I would recommend this to a friend.
