[Roadsters] correct oil weight oil to use

[Geatti, Marco]

I have a 1969 Roadster 1600. Engine is fairly tight, doesn't seem to
burn any oil. What weight of oil should I be using? I looked at the
manual and it had a range of 10w to 30w depending on climate. I bought
some 10w30 on the weekend but wondered what everyone else is using. I've
heard some using 15w40. Any input would be appreciated.



Thanks M.
