what does this mean??? or is it the diference in labs at my oil intervial of 8000 miles without a bypass filter this was my test results from Blackstone:
Aluminum 4
Chromium 1
iorn 21
coper 1
lead 2
tin 0
molybdenum 105
nickel 0
manganese 0
silver 0
titanium 0
potassium 0
boron 121
silicon 7
sodium 3
calcium 3565
magnesium 17
phosphorus 1134
zinc 1334
barium 0
Now I swithced to a local lab for me and this was my test results with 3198 miles and a bypass filter installed were:
Aluminum 3
Chromium 4
coper 2
iorn 10
lead 4
tin 4
silicon 10
sodium 1
water less than 0.1
oxidation 3.1
viso@100 13.6
glycol 0
fuel less than 2.0
tbn 9.2
nitration less than 2.0
soot 0.1
blackstone said that oil was at average levels but aluminum was a bit high but ok. now lead is higher with less miles, tin is higher, silicon is higher. any input would be helpfull.
thanks

The silicon could be dirt, or it could be an anti-foam additive that will decrease with miles used. Mobil 1 starts out at about 10ppm on silicon on a virgin oil analysis. It could also be due to gasket seals if this is a newer vehicle with few miles. So it just depends on the oil you are running and your vehicle. I would suggest getting a virgin analysis of the oil of choice, so you can determine the source of the silicon.
The higher Iron does suggest it could be from dirt. Higher wear could also be explained due to cold weather conditions. These aren't terrible numbers and if the first one is in the summer and the 2nd in the winter, then I doubt this is anything unusual. Bypass filter won't reduce wear in the short interval, only in the longer intervals in my opinion.

thanks for the info
my f25o has 103000 and it drive like it just left the show room floor. I was planning on doing a virgin oil sample test. but I did'nt know what it would show. I just installed the bypass filter at 98000 miles and i've only today pulled a second oil sample so we will see what happens. I'm thinking the high iron might be from my sample tube i use.
thanks agin for the great info

I agree w/ Jim. The numbers are very small and look pretty good.
Think of it like this...you have to drive 1 million miles. You start out by driving 4 miles and stop for a coffee. You then drive 4 more miles and stop to pee. You have now doubled the mileage since your first stop but you have still only driven 8 miles out of 1 million. So, the "higher" number is not very significant.
At these very low levels I tend not to fret over smaller changes.
MY 2 cents....

Interesting that you use a K&N. You know that they filter better as they get dirty, don't you? I still feel that they let more dirt by, but can't decide if it's really significant. At your mileage, I think it might be.
Had any throttle body problems?

Thanks,
I realize that they do test in ppm but the lower i can get and keep the numbers I figure the engine will run that much longer.
I would install a bypass filter on a gas engine. I'm planning on installing one on my wifes pathfinder. They clean the oil to
1 micron and its around 5 microns that engine damage hapens, and most high flow filters (main filter) only clean to about 30-40 microns. so any engine will benifit from one check out
www.oilguard.com thay are the best that I have found.

I just recive my oil test report here is the #'s
Aluminum 4
Chromium 1
Copper 9
iron 54
lead 8
tin 2
silicon 11
Potassium 0
sodium 3
moly 6
water <0.01
Oxidation 5.6
Visc@100 13.7
Glycol None detected
Fuel <2.0
TBN 7.8
Nitration <2.0
Soot 0.5
the oil is chevron delco 400 15W40 and the oil has 23237 mile on it. my only consern is the iron it seems a little high. Also it a F250 diesel.

That is not high iron considering the miles. In proportion to mileage that is low. TBN retention is excellent. It has thinned a little, but not down to a 30wt. Except for arctic winters, who needs expensive synthetic with extended drain results like these on Delo?

What whould be a high Iron count
Jim,
what would you consider a high Iron count ? I also talked to the OIL GUARD people they to said I'm right in line. with the amount of time and miles this oil has been in use. they said the main items I need to watch is silica that will tell me when the filters are starting to fail. and the viscosity, and tbn.
Anything you or anyone else would be apreciated
