Not sure if all the 1.6 ecos exhibit the same flaws, or just ours, but from what I've seen, 5w-20 will be watery with fuel in no time...
Anyways, I'd love to hear other comments on the engine. The current fill in ours is Mobil 1 5w30.
I missed your post before recommending the same thing myself: Use Castrol Edge 0w40 and watch the visc drop over a full oil change interval. That oil has the most high performance specs of anything I've seen, and you can get it at Walmart for cheap. ....... Running rich with the turbo and getting blowby past the rings must be whats doing the dilution, I'd guess.
