I just bought a 1980 GL1100 from someone that bought it from someone else about 8 months ago. As such, neither he nor I know what kind of oil is in it. Can I, or even should I, go with a synthetic oil? I would like to change the oil as soon as possible as I have no idea how old this oil is.
What weight oil should I use in my 1980 GL1100? I don't have an owners manual so I'm really not sure. I've not had a bike in about 15 years and back then I always used Castrol 10w40 automotive oil but I now understand that that is not the best oil for a bike as they have differing needs.
What should I be looking for?
Thanks!
