Needing my gearbox oil changing at the weekend, and I'm seeing conflicting stories on what grade I need?
The guy in the shop at the motor factors told me I need 75/90, but reading online in seeing 75/80??
Is there a correct one to buy for 172's and do I need semi or fully synthetic???
Thanks guys :thumbup:
