I needed to change my manual transmission fluid as part of my 75,000 mile service on my 2008 Honda Fit (Jazz) Many people online suggested using the Red Line, and now I understand why. It absolutely improved shifting, including my occasional sloppy shift (where my timing is imperfect) and I am looking forward to increased mileage as well. Nice product.

My favorite oil for my e30's manual transmission. A bit more expensive than other oils, but it is worth it.
