Oil weight?

[SandMan123]

I have a 2016 Scarab 195 HO. In the Scarab service manual it talks about 10W40 non synthetic for supercharged engines. But I also see others are using 5W40 XPS synthetic blend.

I’m confused, can anyone weigh in?

This is why... note the difference between super charged and non super charged too. But the recommended oil is the XPS stuff which is a synthetic blend.
