    I have used Spectro SAE 75W140 transmission and Spector SAE 85 primary chain case oil for the passed 10 years with good results.
    You can get it from https://www.easyr.com.au/?rf=kw&kw=Spectro+oil

    Without going into the technical details Motor and Gear oil have specific characteristics for the application.

    Baron, I use the same Penrite oils myself and am real happy. Supercheap does good deals on the penrite a few times a year delivered to your door, Sometimes as low as half price and I order 2 or 3 of each.
