The supertech is considered good for up to 10000mi, although I think they recommend only going to you manufacturer recommended interval, for a long OCI, I'd possibly consider using the fram extra gaurd over the Supertech since they're pretty close in cost and the Fram has a silicone ADBV, plus you can get the Fram in a PH8A size for an even larger capacity than the PH3600, it should fit your Tacoma.
