oh no here we go, another tread about oil for a scrambler But, i need comments from Aussie scrambler riders and or bonnie riders, mainly for our conditions. I've been using motul 3100 GOLD (15-50) but i feel my shifting action is becoming not as smooth. So i thought about going to a 10-40 or 10-50. Are u aussie guys using this grade? If so what brand, castrol, motul or fuchs? I would prefer to stay with a semi-syn instead of a full syn, so i know the above 3 cater for that. Anyone had a go at all 3?
