ARCO may be the best engine technician on the planet, and singlehandedly design every Honda engine they produce, but his "experiences" absolutely do not mesh with those of anyone I have ever known. He's a short oci guy who recommends HDEO for practically every application. In his experiences he shared with me on another thread, he believes the life expectancy for a modern engine is 40,000 miles, and he has had "a few go between 40,000 and 60,000". He also thinks that cams actuating buckets (like the 2AZFE on this list) "bucket over" cams are the same as flat tappets, and that these engines need SL levels of ZDDP. So take his opinion with a good dose of salt. Timing chain failure on a modern engine? Really? Buy a lottery ticket the day that happens to you.
IMO, this will work fine. Sure there will be abuse of this, people going longer than specd and having sludge issues. But they have those same issues with the current 5000 OCI. And really, the 5000 mile recommendation is a little short these days.
Really, I'm surprised that Toyota doesn't have a calculated Maintenance Minder system. It's 2010 for crying out loud. It would require all the technology and cost of a 99 cent calculator.
