After a complete rebuild on my engine I stayed with the dilemma of what type of oil to use to break in my new engine. Some folks said just use any 30 wt oil, some said use a 10-30 wt. after talking to a mechanic at a British/European shop he suggested using Royal Purple Break in oil for the first 1k miles.
what do you guys think, I'm sure some of you have faced the same question. How did it work for you.
