Running in after engine rebuild
Just having a bottom end rebuild on my sti 3 engine after it threw a big end (no.3 
). Its having new big-ends, mains, crank, one new rod, oil pump and all the engine gaskets replaced. Everything else has been inspected and given the thumbs up.
Is it just a normal run in, i.e. building up revs and boost gradually over 800miles or so. Or, due to not replacing the rings, will a shorter run in period ok?
Also, which oil should be used during this period? Would mobil 1 15w50 be ok?
