When I finally got an answer from VP, they told me to use engine oil in my 130S (which replaced a 120S) even though the gearbox was unchanged. I decided to ignore them, am I wrong?
Are you using ATF? That does seem an odd choice by Volvo for a relatively simply frictional direct drive like a gearbox or sail drive. ATF obviously has it's place in auto-gearboxes or power steering systems when a thinner liquid is needed for the non-friction viscous coupling but in a friction-reliant system I would have thought that something of higher viscosity like 20/30 engine oil or 70/90 gear oil (which are both similar viscosities) would always have been more suitable.
