Scott oiler oil....

[Slaninar]

I've found engine oil too thin and runs too much causing excessive oil to spray everywhere - but the different oil delivery tube lengths affect delivery.
Gear oil is cheaper than official scottoil and flows well on my set up, I use the really thick stuff in summer

SAE90 gear oil is about the same viscousity (thickness) as a 20w60 engine oil. I use either on bicycle chains in the summer, while for winter I use synthetic 5w40, or "thinner".
