When can you change over to synthetic oil and can you change over to soon?
Could this harm the engine if you use synthetic to soon?
Should I change back over.
I'm stock and use v- tech. Of course the dealer didn't make any comment about this.
Got the car w/ 2454 and had the dealer do a oil change w/ syn.
I'm at 4400 now.
Help put my mind at ease.

You shouldn't change over to synthetic before 10,000 miles so the engine can break in properly.

Pssst, v-tech makes phones. Your engine has vtec.

Mineral based oils allow the piston rings and gaskets to properly break in. On here I think the general concensus is 10,000 miles. If I were you I would switch back over. Since the dealer switched it over to synthetic I would ask them to perform a compression test to ensure that the rings are still holding compression. I bought my S used and I am currently having my bottom end rebuilt (Piston Rings) and a full top end kit (all the gaskets) and they said they are putting regular Mineral based oil back in and that I should keep it in there for atleast 5k (I will wait 10k). Synthetic does not properly break in the rings and gaskets.

I was wondering what that ringing was. Tx.

I'll change back over ASAP. Thanks for the feedback.

so is the normal honda (semi synthetic) oil considered as "mineral oil" + good for the 1st 10,000 mile or is this still not as good as other cheap mineral oil?

I can understand needing to break-in piston rings. How in the world do you break-in a gasket?
