I then found the average for each wear metal (iron, copper, etc..) for all the UOA results and the standard deviation of each wear metal result from the average. This chart shows the average wear for each current oil tested in terms of ppm/1000 miles. The cells with a green background are better than one standard deviation from the average. The cells with a red background are worse than one standard deviation from the average. The average and SD, remember, is calculated from ALL the samples I have from the VQ. The average wear characteristics of some oils used in the VQ which are no longer in production I have also included in a separate table.

The interesting thing is to note which oils are statistically significant in terms of better or worse wear from the universal average for each wear metal. It would be nice to have multiple samples from some of these oils before the manufacturer changes formulas again.

just stick with what you like and don't rub it onto other ppl.....this thread is turning into a religious ppl trying to convince you to convert thread...lol

Castrol Syntec 0W-30/5W-30 did good from that chart

NIZMOZ · 05-27-2009, 03:27 PM

Castrol makes good quality oils. Especially the German Castrol.

nogoodname · 05-27-2009, 03:30 PM

i've been using it for awhile..... i used regular Castrol on one car to see how long it lasts.....25K til white foamy stuff starts coming...lol

it's true......when a car gets old..sometimes you just have to stop paying up for repairs and maintenance....that's what i did

it was a '90 Grand-AM btw

it was still able to run, it got so bad that the dip stick was rusty...

nogoodname · 05-27-2009, 03:42 PM

results from
http://www.blackstone-labs.com
http://www.dysonanalysis.com/index.html

all cars were 350z's

All the data collected together

nogoodname · 05-27-2009, 03:44 PM

results from a 08 G37 with Nissan's 5W-30

and results from same car at 2nd oil change...same oil too

nogoodname · 05-27-2009, 03:53 PM

where do these elements come from:

Iron: Comes from cylinder liner, camshaft, oil pump, and timing chain wear
Chromium: Comes from piston ring wear
Copper: Comes from bearings, valve guides, and bushings wear
Lead: Comes from bearing wear
Aluminum: Comes from piston and piston thrust bearing wear
Silver & Tin: Comes from bearing wear
Silicon: dirt ingestion, sometimes used as an anti-foamant
Molybdenum: anti-wear additive and friction reducer
Boron: anti-wear additive and friction reducer
Calcium: common additive with many functions, primarily a detergent
Magnesium: common additive with many functions
Phosphorous: anti-wear additive and friction reducer, shear stabilizer
Zinc: anti-wear additive and friction reducer, shear stabilizer
