I recently purchased a '04 Pilot Ex. Previous new vehicles I always performed the initial oil change at 1000 miles and then followed the mfg's recommendations there after. After reading the oil change posts on this forum I became totally confused as to the correct procedure to follow. I called my original dealer and he recommended I bring my truck in at 5000 miles and he would use Valvoline 5w30. I checked a other Honda dealers and each had different a different answer.
Since I have used Amsoil products in the past with good results I decided to e-mail them to see what they had to say. Here is their reply.

Our AMSOIL XLM 5W20 is an excellent choice for this application. You can change to XLM right away! We do recommend however to operate the engine up to its first normal drain interval with the factory motor oil. There are a couple primary reasons for this recommendation.
1. New engines or engine components generate high wear metals to begin with and generally contain debris from machining and assembly. It is more beneficial to allow these wear metals to collect in the factory motor oil than to circulate throughout the crankcase for extended periods in synthetic motor oil. By operating the vehicle to its first drain interval with the factory oil, these wear metals and manufacturing debris collect in the oil and are then flushed out of the crankcase when drained. This allows for a much cleaner operating environment for the synthetic lubricant.
2. Within the first miles of operation, if there are any defects in the assembly or workmanship of the engine components, then they may be corrected before installing the more expensive synthetic motor oil.
Thank you,
