Welcome to the message board Eurico.
The engine oil should be 20w50 with the zinc/ phosphorus, ZDDP for older engines. I use Valvoline VR1 but don't know if it's available in Europe. 4 stroke motorcycle oil will also work.
The 4 speed gearbox also uses the 20w50 engine oil or synthetic Redline brand MTL. Other brands will work fine.
The diff uses 75w90 hypoid gear oil. Synthetic is ok.
I have had good luck with Dot 4 synthetic brake fluid.
The pent roof 4 valve head is not sensitive to octane. You should not need any fuel additive. This engine can easily run 11:1 compression on pump gas.
