I would say that if you are talking about internal engine bolts and screws that that is what I also use for them.
And if it works good for you... great.
I think you might find professional mechanics use the blue for general external nuts and bolts... because it is much cheaper and works good.
Also... I might be thinking of the "Stud and Bearing Mount" Loctite (red also.. which is not supposed to come apart)
But I will admit... there is one bolt on one of my bikes that DESPITE loctite... I have still lost about 5 of them !
I think red is my next step.
