That was my 1st and only analysis thus far, which I did a couple of month ago.
Lead = 20ppm
Copper = 5ppm
Actually, my interval was actually closer to 5K miles than 6K.
I still have Castrol 10w60 in it right now, but thinking about trying something else on the next change. I also like to see more data points prior to taking any action.
I've also heard about Techron increasing lead reading, but my sample was taken (through the dipstick) prior to using Techron treatment. Then changed the oil a couple of tanks after using the Techron treatment. But then again, I've been using mostly Chevron gas, which contains Techron. May be that's what is contributing to to my high lead reading?
