meadowbrook Posted July 4, 2016 Report Share Posted July 4, 2016 Hi all, I have an R7 Borg Warner 3 speed manual on my '50 Meadowbrook. I bought it from Asche a few years ago and was wondering about what to use on it if I change the lubricant. I am ready to just do what Asche recommended, Amsoil 15W40 engine oil, which he called 'sticky', as in hanging on to the gears longer. Just wondering what others here use. Interestingly, the original trans lube recommended in the manual for the standard 3 speed is 10W engine oil, so that makes using the Amsoil seem correct. However, it does leak through the rear seal, despite me changing it. Otherwise, the trans works well. Quote Link to comment Share on other sites More sharing options...
steveplym Posted July 4, 2016 Report Share Posted July 4, 2016 This is the stuff I use in my R-10. I ordered some from Fifth Ave and this is what they sent me. So from now on I just go to my local Napa and order it. 1 Quote Link to comment Share on other sites More sharing options...
James_Douglas Posted July 4, 2016 Report Share Posted July 4, 2016 Unless I am mistaken, SAE 10W was specified with the M6 Trans (Semi-Auto) and SAE 80W was specified with the Three Speed Trans. James 1 Quote Link to comment Share on other sites More sharing options...
