Turnerdv10 Posted December 13, 2018 Share Posted December 13, 2018 They should tell everyone before you buy a wrx sti to expect big bills every week . Does anyone know what the best gear oil and brand to put in the wrx sti Hawkeye gearbox 6 speed to quieten it down . Sick of the whining especially if going down a hill in gear or low gears . It prob needs looking at but will have to wait till summer . Garage before me I think put 75/90 don’t know what brand. Been gradually getting worse .

Jay762 Posted December 14, 2018 Share Posted December 14, 2018 75w/90 gives consistency over the biggest temperature range of the recommended types, not sure its going to stop the whine though Quote Link to comment Share on other sites More sharing options...
