That oil is significantly THINNER than the recommended BMW 5w30... And THAT is way thinner than the 10-60

If you look at the actual viscosity specs of the BMW 5w30 it runs like a 5W40....which is why Doug Baker (above, 4 year ago... wave) suggested those oils.
Keep it as simple as possible...but no simpler.
