Speed TC - Check the many UOAs for 0- and 5W20 oils, you'll see very good results for Fords, Hondas and others. In the colder winters of the Chicago area, 5W20 makes sense to me. For summers, 5W30 might seem more comfortable, but we've been running 5W20 year round in our Honda for several years, and the UOAs for both summer and winter have been very good.
