My '06 HCH has 1,200 miles on it so I bought some mobile 1 0W20 full synthetic to have the Honda dealer put in this weekend. When I went up there the guy in service said it was "waaay" too soon to change the oil and that I should wait until 5,000 miles. He said the break in oil and special yada yada and that the engine needs several thousand miles to break in. He also said don't switch over to full synthetic until atleast 10,000 miles. Anyway, he was saying it would actually hurt my car in the long run if I took out the break in oil and changed to full synthetic at 1,200 miles today.

(He actually pulled out some Honda document saying don't do the first oil change sooner than advised...but it was from 1996!)

My thoughts were to change the break in oil out sooner than the 7,500 mile service interval to get rid of the dirty (from breaking in) break in oil and put in the mobile 1 full synthetic in. No need to keep the tiny engine break in metal particles in the oil for an entire 7,500 miles, and the new synthetic oil might give me an extra mpg or two.

I think it's fine to change out the break in oil at this milage, I've done it on previous vehicles with no problems. Heck, on my old Honda CBR motorcycle I changed out the oil at 500 miles and put in full synthetic, never gave me any problems, ran like a champ and you know it was run a lot harder than my hybrid. And going to full synthetic "too soon", more and more cars are coming with synthetic blends or even full synthetic from the factory now.

BUT.... before I did anything I wanted to get "ya'lls" opinion.
