2007 Town & Country and suggests 5w 20, the engine has 160k miles and is using more oil than normal. Can I use a slightly higher viscosity oil? I am going to use an engine additive and would appreciate any oil suggestions. Many thanks...

Before resorting to any tricks first inspect the PCV valve and any related hoses. Both times my van with the 3.8 started using oil the PCV system was the reason.

5W-30 would be fine, but as noted above won't make much if any difference in consumption.
