After seeing what Yun and others are using with Mobil 1 high mileage 10W-30 I may use that instead with it being so easy to get and no shipping to pay for. I just mailed off an oil sample (Blackstone Laboratories) to see how the AMSOIL AMO 10W-40 is doing after rebuild break in and what the phosphorus and zinc actually is.

As for oil filter, check out all of Marc's research and you can't go wrong: http://www.zr1specialist.com/HAT%20W...ers%202006.htm

I bought a case of Fram TG3985 for about $2 each when Rockauto.com had their closeout so I guess I have a lifetime supply and I see Marc has updated recommendation since.

Craig,

Mobil 1 high mileage 10-30 sells for less then $25 in a 5 qt jugs at the Walmart - not a bad price.
