rebuilt engine break in oil

[BYprodriver]

Start with the JG BR-30 & run it about 300 miles. Start out in stop & go traffic trying to get the temp up to 180+ constantly varying rpm without exceeding 3500 rpm.

By Pro, is there a second choice to Joe Gibbs. I'm not sure I can find Joe Gibbs up here in New Brunswick. I called 3 different Auto Supply stores and no luck but I'll try the engine rebuild shop tomorrow, maybe they can order it in.

What about after I drain this initial stage oil off, I still have to use conventional type oil for the next 1000 miles don't I? What weight?
The Dt 40 (5w40) is synthetic?

You can order the oil from L&N or Flat 6 Innovations' web sites. About $150/case of 12 bottles.

Yes, the Joe Gibbs DT40 5W40 is a full sythetic oil. High in Zinc and Phosphorus.

Send Jake or Charles (L&N) an email or PM with your other questions.

It may be hard to seat the rings, you should consult whoever honed the cylinders.
