Looks like wear increased as would be expected. Am I missing it? What is your opinion.

 

[zaluq]

Both oils was used only one weekend,the first analyse is just after 6 hours, oil is changed between races. Its two different brands , but the second analyse has 3 times the use of the first. So i am asking which one is holding up best, and yes i am a neewbie on analyses.

We have no way to know the base numbers.We need a control and even then,you'd have to take into account race variables.

I think I'm saying that right.

Would really help to see the numbers side by side, like this-

Al 2, 2
Fe 10, 15
Cr 0.3, 0.7

MUCH easier to compare that way...

Tried it , but that was the best i could make, without 2 hours of notepad edit, i tried coded and html also

Yes. you are saying that right. We are comparing apples to oranges. One was used for one race, the other for three. to make some case it should have been one to one.

Am I reading this correctly?

Copper - 32 ppm

Lead - 53 ppm

Im not sure about the lubricant but I dont think i like those numbers...
