Just put in my order for my Large Swamp Runner. Bought the 670 Predator a couple of weeks ago , on sale, just now the gizmo part of it from SR. Put it together next weekend and I guess idle it for 3 hours with no load ( heard that was the break in reccomendation) . Empty the metalized oil, add Royal Purple and head to the lake for some scouting, a few brewskies in celebration and some learning and some fun. Do you think breaking a bottle of cheap beer over the engine would hurt it? Ha. What do you guys think about the break in proceedure? Also synthetic oil or dino oil? Any extra additives like BG products, Lucas etc?
