What type of gear oil do you use in a fa50?
what type of gear oil do you use in a fa50? just got scooter and previous owner knew very little about it.
The FA50 should only have 10w30 oil. Whether normal or synthetic will not make any difference to the performance. Too much oil will cause problems so measure carefully. The gear train sits in the oil and so does the clutch. Replace the oil once a year at least. I often add a little oi additive like Slick50 or Motorcoat to keep the gears well lubricated.
That depends on a few things, like altitude and the atmospheric temperature. Most times, anything on 2 wheels will do fine with a 80w90 gear oil. If you can find. You can find this at any automotive-supply store, or anywhere with a decent automotive department.
