<VV> Engine oil: synthetic or mineral?

[Arend Huisman]

As we finish my engine in the next three months, i am trying to figure out what engine oil to use. I already know, that i have to use a product with enough "ZDDP" (zinc-additive) in it, but i am not shure about the dicision to use synthetic, partially-synthetic or mineral oil. Do some of you have suggestions?
Thanks in advance!
