Great writeup. I finally broke down and bought oil (my jx35 requires NS-3) over ebay (dealership wants $20/quart, ebay was around $12). The hardest part was that stupid filler cap off. Hate that thing. I broke it enough so I never have to put a screwdriver in to pull it.
Since mine drained 4 quarts but holds 10, I'll change it once per year instead of the dealership-recommended 60k.
