thats what i used..i changed mine after 500, then again after 1500..then switched to mobil 1 15w-50 full syn..a lot of different opinions on how to break in rings..some say run it like you plan on driving it, some say take it easy..i boosted mine after 100 miles...no problems w/ blow by that i can see..
