Thanks Doug!

I didn't think it was a weight number but didn't know what is converted to.

thanks again!

The number you are referring to is a Harley part number.

Harley oil translates approximately to;

105=60w
75=40w
58=20w

I want to change the oil in my 60 165 tarns/primary. I know the service manual calls for HD 75 (Med Heavy)oil, but what is everyone using/substituting?

Thanks!
