Hockey

First of all, thanks to Road Rage for hooking me up with Blackstone Labs and their Oil Analysis.

For a brief description of my car......I have a MY00 with 75k on it now. I switched to Mobil 1 Synth 10w30 at 60k miles. My car is stock as far as drivetrain goes, and I drive it pretty hard on the street and in the canyons. It sees high rpm shifts more often than not, and I have had absolutely NO mechanical issues (knock on wood).

I sent my oil sample to Blackstone Labs and they returned the following comments:

"The oil is treating your engine well, and the oil change interval of 6000 miles was not too long. You could even extend it to 7000 miles if you wished to do so for the next sample. The universal averages column shows typical wear from this type of engine after 4200 miles on the oil. Your wear is generally lower than average, after more miles on the oil. We can tell you're treating this Honda well. Air and oil filtration look okay. We found no gas, moisture or signs of any coolant in the sample. Check back to establish solid wear trends."

I don't have a scanner to post my actual sheet, but the ONLY sample that came out above normal was CALCIUM @ 2654 compared to the average of 1927, and BORON @ 135 compared to 90. I think this may just be the inherent properties of the oil, but I am not sure since I am no Oil expert.

All-in-all I am very pleased with the results. As I stated, this is a higher mileage motor that gets a workout all the time..............but seems to be holding up VERY well.

Thanx again guys,
David "Hockey"

very interesting. i've been running Castrol Synthetic lately, i might give Mobil 1 a whirl and see how it does. good post.

Good info, Hockey. If you're bored, it would be nice to see what your wear metals looked like, and your TBN. For your info on Calcium and Boron, look at this VOA table I've copied from BITOG:



As you see, the Ca & B values are pretty much in line with the virgin oil analyses of Mobil 1. I wouldn't get too bent out of shape about there being a difference because there is variability in the testing as well as in the formulation.

QIKSILVR

What were your values for iron, lead, dirt, viscosity, flash point, fuel contamination, tbn? Those are the more important ones.

Surf2k

These are my UOA values on Mobil 1. Wear was very low but boron was absurdly high.

Copper 4
iron 3
Chromium 0
Lead 0
Aluminum 3
Silicon 8
Moly 78
Sodium 7
Potassium 3
Magnesium 25
Tin 0
Silver 0
Zinc 986
Boron 519
Water Negative
Fuel Negative
glycol negative
Oxidation 170
Nitration 86
Sulfer 115

The oil (M1) had 4,000 miles on it. I live in the city and autocross, so that's 4000 miles of traffic, short trips and flogging on the autoX course. Oh, and it also includes months of sitting this winter. Filter was Honda PCX. 1/2 qt of make-up oil.

Thanks for the info...Mobil 1 rules and I run it in all of my vehicles.

Hockey

Iron = 10 compared to 11
Lead = 1 compared to 2
Dirt.........is that "insolubles"? = 0.3 compared to <0.6
Viscocity @210f = 59.6 compared to 55-62 range
Flashpoint = 410 compared to >365
Fuel Contamination = <0.5 compared to <2.0
TBN = what is TBN, sorry.

water and antifreeze were both 0.

Basically, I'm a happy camper!

TBN=Total Base Number. Basically, the lab would check to see how much more acid the oil could take before it became acidic. It's kind of like measuring the amount of a buffer capable of neutralizing the pH in an aqueous solution.

It appears that you did not request a TBN to be run. Not a big deal, because the rest of your values are excellent, implying that your TBN was still in good shape.

Moisture tends to drive down TBN (among other things) because any water in your oil will react with sulfur (and carbon a little) to form a dilute acid. This will reduce the TBN and when it is depleted, the oil will oxidize, start sludging up, increase wear, and start breaking down its additive ingredients.

The term "dirt" probably meant insolubles. .3 is pretty low for 6000 miles. Your engine appears pretty happy.

Nice numbers! Thanks for posting, David.
