is royal purple the way to go if u just rebuilt an integra LS motor and its the first time u put oil in it?

 

i do not think you should use synthetic when breaking in... it lubricates too good and your parts will never break in.. if you get my meaning... give it a thousand miles or so... and rev that sucker up every now and then.. the tolerances on todays engines are so tight you only have a short time to seat your rings etc..
