He changes the oil once per month, usually at 8,000,10,000 miles. He changed the AT fluid for the 1st time at almost 500,000 miles, but has done it about every 40,000 since. He changed the plugs at 700,000 miles. He had a head gasket go bad at 800,000 miles. The rest of the engine looked fine, but the mechanic wouldn't just change the gasket so they found a 100,000 mile engine in a scrap yard and put it in. That engine now has 600,000 miles on it.

You won't find all that info in the above link, but there are other sources out there. He answered some questions for guys over at the Tacoma World forum recently.

Most people don't really want the truth.

They just want constant reassurance that what they believe is the truth.
