Help! Slow cooked pork with coke - how much sauce?

[WorrisomeHeart]

I'm going to give the pulled pork a go today but am confused about qtys of the coke and BBQ sauce - surely not a whole can AND a whole jar of sauce??? Also how long should it cook for? Will 8ish hours only be ok?

sorry only just spotted this. was it OK? i tweaked the recipe and cooked the pork in chicken stock (covered meat so it didn't go crusty or dry at edges). I then got rid of this - plus the fat that had come off the pork during cooking, and added the jar of sauce to the broken up meat. you can use a cook-in sauce instead - taste wasn't as strong but still fine. cooked for 6-8 hours.

I never add coke, just a bottle of BBQ sauce & chopped onions
