Hi All,
I'm new to the forum, having recently purchased my first BMW, a 1974 R90/6 in decent running condition. Not knowing anything about the maintenance that had been done on the bike I decided to change the fluids after a few short rides, thinking it was a wise decision. After I had done this and gone on a few longer (2+ hour) rides I started to notice that the push rod seals and oil pan gasket were weeping a small amount of oil. I ordered the gaskets and know that I have to completely drain the oil to replace the oil pan gasket. My beginner question is whether or not, given that it's brand new oil, I can drain and then re-use that oil or if I really need to get all new oil. Thanks for your expertise!
