Got me another 2.2 Ecotec for $400 to go in the Saturd. It seems to be in good shape. Supposedly, it only had 37,000 on it when removed from the donor car. I'm putting new timing/balance chains in it for good measure. Rings and bearings still look brand spanking new so I don't think I'll mess with them. Anyway, my oil will either be: Kendall GT-1 blend (I just can't find the full syn locally). or Rotella T6 + one extra quart of something, probably QSAD. Whichever I choose, I will try to use the same oil every change, which is something I've never done before for any engine. OCI will still be by the oil monitor, which will usually take it to ~7500 miles.
