Roughly 3k with Delo 15w30 on my '97 Blazer with the 4.3. I replaced my LIM gaskets last week, drove the truck a bit and changed the oil first thing.
As you can see in the last photo, some crud made it into the engine despite of me placing a bed of towels down into the engine and using a shop vac during gasket removal and surface prep. I'm going to do some pretty severe OCI's until that crude goes away. I'm using an AC Delco PF52 and some Certified 10w30 and will probably change it sometime this week because I'm anal retentive like that.
