When making a decision about what shock oil to use keep this in mind. I found this post from the design engineer of the Blitz.
Hey guys, I wanted to share some info so we care more easily share shock data. To start, let's cover oil "conversions." The most appropriate unit to list the kinematic viscosity is in centistokes (cs). However, since the past rivalry of TA and TL was so intense, I'm guessing they wanted to hide the true measure of the oils and assigned an arbitrary "weight" to them. This makes it a bit difficult to compare shock setups without knowing the oil brand.
Quite a few companies list their oils in a straightforward manner: Xray, Mugen, Kyosho, HB,
For these oils, the number on the label is almost exactly the centistoke value of their oil (within in a tolerance range, +/- 20ish?). So 300 Mugen is very close to 300 Kyosho.
HPI oil (bear with me as I did not pick this ), is listed as "weight," but in acuality, a modified version of a centistoke labeling. Just add a zero to our label weights to get the true centistoke value. 35 "weight" = 350, 40=400 and so on. So our oils will compare directly to those in the list above.
Now for the TA/ TL oils... I've got a list of the cs values for each weight (measured) for comparison.
TA
10=108
20=208
25=286
30=373
35=454
40=525
50=707
60=725
70=960
80=1040
TL
15 =110
17.5=158
20 =243
22.5=243
25 =294
27.5=345
30 =381
32.5=397
35 =459
37.5=477
40 =546
45 =657
50 =886
60 =844
70 =970
So, if I wanted to use an Asian/ Euro oil to match say a Losi 70, I need either a 900 or 1000 (yes diff oil).
Hopefully this helps when sharing shock data!
