Question
What oil should we use in our 1987 325i 5 speed manual transmission Getrag 260. I'm replacing the one in it with a used one. I think we tosted the last one by using the wrong oil type last time we changed the oil. We used a 80/90 weight gear lube.
thanks in advance.

Answer
Robert,
 BMW made tranny's for these cars that used 2-3 different lubricants in them.  Each transmission has a colored sticker on it, and the color denotes what type of lubricant is to be used.  The Gear lube would be fine as long as that's what is called for by the transmission.
