Hope you can read this alright. I scaned it from my 01 Tacoma owners manual. Seems to be allot of misunderstanding about what you can use and what you can't use. Had a complete flush done on mine 34,000 miles ago and used Shell Dex-Cool extended life to refill it . This is just the same stuff Toyota requires and nothing more and nothing less. Never had a bit of trouble with it yet and will flush and use the same stuff again when I reach 40,000 on this stuff. I don't claim to be a genious but I have to figure that the Toyota engineers know more than I do and that engineering is one of the reasons I love my Tacoma, Mike
