Bob, how long do you use the ZDDP oil on a freshly rebuilt engine?

It is advisable to run a ZDDP Additive for as long as you own the engine. I run Mobile 1 15/50 and I always add one qt of Rislone Engine oil Supplement with Zinc Treatment at oil change. I also add a half ounce of Cam-Shield at 2000 miles and change oil every 4000 miles.
