good afternoon,

many years ago, when I had my first /5, I was following several threads that were dealing with motor oil choices for these fine machines. If I recall correctly, there was mention of a Brand, Spectro, that had properties that are better suited for the aging seals, don't want to call it "swelling" the seals but perhaps might slow leaks. Is it wishful thinking or am I correct in recalling that fact?

I just got another R60/5 and want to change all fluids, after giving it a good bath, and if Spectro indeed can help with minor leaks, I sure would use it.

Thanks in advance, again
