What I want to know is, is the oil an actual "Break in" oil or is it just because it's the oil in use to break in the engine, it is referred to as "Break in" oil?
Pennzoil is great oil, it constantly receives great UOA's and VOA's at bob is the oil guy.com (bitog.com) from all kinds different motors and manufacturers.
I currently have 2, 5 litre jugs of of 5W-30 I'd like to use but I am leery because of the weight difference.
I doubt very much any harm could be done using it as opposed to the 5W-20, but I think I will wait until my motor has at least a few thousand miles on it first.
No on break-in oil they use regular weight, otherwise they would have to specify a shorter oil change interval for the first one.
