Re: Volvo transmission Fluid
No, you don't absolutely need to use the Volvo oil.. but having been though this myself not long ago it's certainly less hassle:
Head down to your nearest Volvo marine dealer. They'll sell you however much you want from a big drum out the back (over here it's $7 per litre..)
From RFC 1925: "(3) With sufficient thrust, pigs fly just fine. However, this is not necessarily a good idea. It is hard to be sure where they are going to land, and it could be dangerous sitting under them as they fly overhead."
