i hope they figurre out what i need. at your suggestion, i am about to make my first of many 'hot and frequent' oil changes. i turned over 100 mi. on the new engine today, and and just returned from one of my break-in jonts. i am waiting about 15 mins for the oil to drain to the pan. i've chosen shell rotella T as the oil of choice. its 15w-40 (a little heavy), but it should aid in keeping the cam and rockers in top shape. thanks for all the help.
