+This evening I changed my oil to full-synth AMSOIL 10w40 w/a Polaris
filter (at 61,795 on the odometer). I'm going to stick with the
factory-recommended oil change interval of 2500 miles while continuing
analyses on the drained oil for an idea of what's happening in
comparison to the Victory oil analyses. (Prior analyses are viewable
in the Victory Tech - oil

I recently received a message from another owner regarding a NAPA oil
analysis conducted on two new random samples of Victory oil. Both
samples were new, neither sample was purchased near the same time, nor
were they purchased in the same type of container (gal. vs qt.)...

The writer queried my opinion.

My response:

+I wish I knew more about oil additives, etc., however, I was at least
pleased to see comparatively similar results from the two batches.
That's a good sign that the oil going IN is consistent in its makeup.

One could assume, then, that the oil coming OUT has been subject to
varying internal forces causing inconsistent results.

Compare your new oil numbers to my used oil analyses to date (shown on
the right):

(your new) (Roadkill's -->)
silver 2 1 0 0 0 0 0 0
0
aluminu 1 0 6 13 8 7 4 2
5
chromiu 1 0 0 0 0 0 0 0
0
copper 1 1 1 1 1 2 2 1
3
iron 1 1 9 13 11 26 39 21
13
lead 1 2 2 1 7 2 1 2
3
silicon 13 11 0 0 0 0 0 0
4
tin 0 0 3 2 7 3 2 2
2
calcium 1459 1347 444 142 54 263 80 -47
353
magnesi 600 558 177 56 19 98 34 -18
133
zinc 987 977 323 123 43 225 19 -49
190

So, questions immediately pop into my mind:

Where did the silver, silicon, calcium, magnesium and zinc go? Burned,
one should presume.

Where did the aluminum, iron and tin come from? Wear items from
internal parts, right?

The clean numbers would tend to put the Victory Oil user at ease in
terms of consistency in makeup. My latter numbers could tend to cause
unease to the average bike owner in terms of motor wear, though the
numbers are reportedly within acceptable range. You'll notice that the
only truly unusual sign (to my untrained eye anyway) are the
calcium/magnesium/zinc levels in the second column from the right; the
column containing the negatives is the last analysis from #2656 before
failure of 3rd gear. (The last column is #219's motor with ~11k or so.)

Could the extreme numbers in the last #2656 column be a sign of
impending concern?

Zinc is the prime anti-wear additive in Victory's oil. Zinc provides
protection from metal-to-metal contact on surfaces such as cam lobes
and followers, as well as piston walls. They also protect at bearing
surfaces, when oil pressure is too low to build up a protective film.

Magnesium and calcium are anti-corrosion additives designed to counter
the sulfur dioxide produced from our gasoline which is thus pumped
throughout the motor during the combustion process.

So, to sum up what I think I'm looking at, my anti-wear numbers and
anti-corrosion numbers in the last analysis on #2656 don't appear good,
to my untrained eye, but are reportedly within acceptable range.

Can anyone provide some input?

Ride on.

Roadkill, I posted this question over on the VMC board but you must've missed
it, but why are you going with the 10w40 instead of the V-Twin 20w50 ? Just
curious. I'm thinking about switching over myself, but I'm leaning toward the
20w50.---gman

+I chose the AMSOIL synthetic high performance 10w40 motorcycle oil
based upon their recommendation.

These two references are probably the quickest way to catch up (culled
from a full "AMSOIL" search on the Victory Digest):

I'm very interested in seeing if either of you get any clutch slippage
being you're running "pure synthetic" instead of para-synthetic.
Clutch slippage is what they always say you will get by running a pure
synthetic. Y'all run your Vics hard enough that it should show up if
any of these claims are true.

Keeping eyes and ears open,

Thanks for the reply RK. Now that you're running the Amsoil, do you notice
any difference in the mechanical sounds from the engine or tranny ? I called
Amsoil yesterday to see when the catalog and info I requested 2 wks ago
might be arriving. ---gman

+No clutch slippage that I can see or feel yet with about 450 miles on
the AMSOIL.

I'll keep an eye out for it though.

Ride on.

+No difference in the mechanical sounds to these ears.

+You might be better served looking everything up on their website like
I did; it's pretty well detailed there. http://www.amsoil.com/

Afterwards, you get a TON of info when you sign up.
