I'm afraid that's pretty typical, regardless of oil weight used. It's a big part of the reason I'm not a fan of blindly extending oil change intervals regardless of the oil type, or weight used.

Although it seems odd thinner oil isn't necessarily "bad" where fuel is present and other factors about a chosen oil can be much more important than it's rated viscosity.

My last report was about 1.6% fuel dilution.
