Bought a remanufactured engine and was curious about recommendations for a break in oil for the first 500 miles? And any other tips to make this motor last for another four hundred thousand miles?

Oil.
Seriously. At this day and age, most of the wives tales are just that. Hooay.
Do what the rebuilder recommends.
Maintain whatever warranty you have.
There was no recommendation by the Rebuilder, I know enough not to use synthetic from the start I was hoping to find something high in zinc in a 5 W 30 for the first 500 miles?
Joe Gibbs break in oil is what we use on everything in the shop.
get a bottle of rislone from the store. like this https://www.grainger.com/product/RISLONE-Engine-Oil-Supplement-36D348
and conventional 5w30
Use correct spec oil and be done. There's no real voodoo about it. GM uses mobil1 as fills in several engines so I wouldn't even be all that worried about using a non-synthetic.
I'd do either the Joe Gibbs Break-In Oil or Delo 400 and that Rislone additive, either/or. And then change the oil early, like at 500 or 1000 miles. After that just do whatever you whatever GM calls for.
The rebuilder didn't have a recommendation? That's not confidence inspiring. What's the engine, what kind of cam does it have and what kind of rings?
In reply to APEowner :
Bought through the local O'Reilly's, rebuilt by power torque? Came with a melling oil pump and mahle gasket set. Engine has a 3 year unlimited mileage warranty so that was the main reason I bought this one, that and I know the manager very well if there is a problem I can look him directly in the eye balls
In reply to Trans_Maro :
Where can I find Joe Gibbs break in oil? I don't recall seeing it on the Shelf anywhere but I've never really looked for it.
They went through a name change but it's still connected to Joe Gibbs I believe.
We get Joe Gibbs from our FLAPS here in B.C. Lordco Auto Parts.
If I couldn't find that, I'd use Rotella T4 and not worry too much.
Special break-in oil is a thing of the past. You used to want higher ZDDP (zinc compound) additives to help the flat-tappet cam/lifters to not munch on each other during break in. Since nearly everything since the 80s is roller cam, it is a non-issue.
Run the oil you will run in it forever, I would just change it at 500 miles, then another 1000 miles (1500 total), then go to your normal intervals. The logic there is that no matter how clean things were before assembly, machined particles and shavings can still be around and you want frequent intervals for the first bit as they get washed into the filter.
