I am still going through the initial break-in on my rebuild. I used the lucas 30w break-in oil for the initial 500 miles with a filter change after the initial cam break-in and driving procedure. Then I changed to the 10w-30 valvoline conventional. I'll run that for the first oil change interval(about 3-5,000 miles) and will then go to a 5w-30 Mobil 1 synthetic for the foreseeable future.

I like that info. So for initial break in use a whole 16oz bottle, then the next 1000 mile change after that, use maybe 1/3 to a 1/4 bottle. And a 1/4 or less for subsequent oil changes.

And my reason for choosing the K&N gold, is from the research done on a show I like to watch called Engine Matsers. They tested about 20-30 different types of filters, and the k&n out performed Wix and AC Delco, and all others. It actually tied a couple other brands in the particular field, but on all fronts, it seems like the best choice over all.
I'd suggest watching that episode. It was pretty interesting. Engine Masters oil filter debacle.
Thanks, I will check that one out.
