Here's another suggestion.

Check out the Amsoil 5W40 diesel oil. Quite a few folks are switching to 5W40. This viscosity on this one is thicker at 100C than the Euro 5W40 and it has a higher High Temp High Shear.

I might be trying Amsoil my next change.

edit: If you have cats, I wouldn't run the 5W30 HDD. It has higher levels of detergents and anti-wear additives than the diesel 5W40 (DEO). The DEO is for use in applications where API CJ-4 (the latest diesel spec) is required. edit again: Oh, you're catless! FYI, for catted people then.
