Oil Analysis NEW THINKING ?

[redeye]

I was thinking last night about this analysis & came up with the following conclusion. Please feel free to correct me if I am wrong.

I went 6,926 miles between oil changes. The data base average was 1,390 miles. SO, I had 4.98273381294 times the average miles on my sample. For this problem I rounded up to 5x's the miles on my oil sample compared to average.

I then took the average variables & multiplied by 5 to see where my analysis would fall. I posted the results below;

Oil analysis for this unit:

Aluminum 25
Chromium 2
Iron 88
Copper 25
Lead 4
Molybdenum 9
Silicon 10
Calcium 3191
Magnesium 11
Phosphorus 1110
Zinc 1355

Universal averages:

Aluminum 7 x 5 = 35
Chromium 1 x 5 = 5
Iron 14 x 5 = 70
Copper 7 x 5 = 35
Lead 2 x 5 = 10
Molybdenum 27 x 5 = 135
Silicon 6 x 5 = 30
Calcium 1524 x 5 = 7620
Magnesium 418 x 5 = 740
Phosphorus 992 x 5 = 4960
Zinc 1208 x 5 =6040

As you can see, my numbers are quite lower when you multiply the data base by 5. Am I wrong to assume that the Rotella synthetic did it's job over the life span of 6926 miles?
