Also, an important note on fluids. ONLY USE GL-4. DO NOT USE GL-4 / GL-5 COMPATIBLE.. Here is a link to a great article
about the GL-4 and GL-5 fluids. Jump down to page 12 for the recommended types and brands.

I just bought the DRIVEN 80-90 wt which is an oil company Joe Gibbs Racing started back in 99 or 2000. It is not on the list but It meets ALL of the described criteria in this article. I can also order it through Advanced Auto Parts and used a 25% off coupon. So it was only $7.50 a qt. I bought 6. I plan on changing it out completely.
Liqui-moly was one good one I can get local as well as the Amsoil. They are $20.00 a qt.
