I've been running extended service intervals with Amsoil for 35 years, including many new vehicles under warranty. Provided the engine is mechanically sound, there are simply no issues - the oil works exactly as advertised (several of my oil analyses are posted in this forum). In vehicles under warranty, I also take used oil samples at the end of a 15,000 mile change interval and have them tested. This is done mainly to make sure the engines functioning normally. This is the procedure I'd recommend for new vehicles under warranty. Once you've established a suitable service interval, there is no need to do oil analysis, unless you strongly suspect a mechanical issue.
As for the filter, Amsoil does not yet spec one for this application. I'd recommend using the OEM filter and changing it halfway through (6000-7500 miles or six months), your anticipated service interval for the oil.
