nashlovebrown,
I would suggest you to use MOTUL product.
You might need to test different viscosity for your ride.
Every viscosity will generate different characteristic on the engine.
You may start the engine oil using:-
Medium Range
1. MOTUL Turbolight 10W-40 (Semi Synthetic)
2. MOTUL Synergie 15W-50 (Semi Synthetic)
Higher range
1. MOTUL Chrono 10-40 (Easter base - Fully Syn)
2. MOTUL Competition 15-50 (Ester base - Fully Syn)
U need to decide which 1 to choose because each viscosity are for different purposes depend on your engine HP. The hotter the engine will require different grade/viscosity.
Changing interval depend on you also. If everyday speeding means need to change frequently also... but for me i choose not more than 5,000km & 60 days (Which ever come 1st) & slow driving style...
About the LSD oil, I would recommend the MOTUL Gear Competition 75W-140
Hope this might help you. After all it just a suggestion.
