If you had any questions as to what kind of oil and/or coolant is best for your Toyota, this might help.
Its from a Toyota Complete Maintenance Care booklet they gave to the Service Advisors at the dealerships...

6 out of 10 [Toyota] vehicles come with Exxon Mobil as "factory fill"

I bought my car at 350,000km, and the owner had been using Quaker State 10w30 conventional for at least 8 years. The motor is strong, smooth, quiet and clean. He kept everything up to date, and the oil is nothing special.

Now, I have switched to Castrol Syntec 5w30. It's a thinner base oil, sure, but I actually have less oil loss between changes, and it stays cleaner. I'm also using Fram Synthetic filters. They seem to do a great job.

The first time I changed to the Syntec, I flushed the engine first. When I pulled out of my shop, I could feel the difference in performance. On a 350,000km motor!

I'm due for a transmission fluid change, and I'm unsure of what to use. I want something with top-tier friction protection to help the old parts last, but also good for the -40/+40C temperate range of Canada.

To the poster who suggested Syncromesh, is that for the autos? Isn't that the GM manual fluid for Cavaliers, etc? How does that compare to 80w90?
