Just found this on the Tundrasolutions website, relating to a TCH service bulletin. is this synthetic oil?
"
EG018-06 ILSAC GF-4 ENGINE OIL RECOMMENDATION
3/29/2006 - 2006 – 2007 model year Toyota and Scion vehicles.
Toyota Motor Corporation manufacturing plants have begun using ILSAC GF–4 engine oil. This engine oil is recommended due to its superiority in terms of fuel economy and engine protection and due to its benefits for both the customer and the environment. ILSAC GF–4 can be used in all Toyota and Scion engines."

QUOTE=Pete4]Synthetic oil is more expensive, probably more than $5-$6 a quart. Dealer gave me first oil change for free, I'm surprised you didn't get first one for free also as a form of advertising for future service, especially that most TCH sell for MSRP, so it's not like a dealer is giving it at cost.[/quote]
