Which manufacturer use which rating?
Which manufacturers you can use same rating oil?
Only manufacturers using cSt as rating are using a world standard and can be mixed used.
Other ratings like W and WT differ from brand from brand as WT or W is not a world standard!

The 50 cSt steps between "cSt" rating are linear, where the 5 "WT" steps used in the "WT" rating are progressive compared to the real thickness of the oil.

We tested this oil supplied by Serpent Benelux on 04-01-2005 in our labaratory and compared them with a calibration oil.of 100 cSt.

Conclusion:
  Serpent oil is way of linear with cSt rating

TEAM Xray has improved their oil line values from December 2006 onwards.
They now have a new silicone oil supplier.

MUGEN SEIKI

Jacco Koch measured 26-05-2008 with the rheometer the following serie of Mugen Seiki oils on request by a driver.

CORALLY

Jacco Koch measured 11-04-2008 with the rheometer the whole serie of Corally oils on request by a driver.
To make sure the measurments are constant Jacco has serie of oils he uses for a standard.
He measured twice the same oil and the values are very close and most of all linear.

Values for the standard measurements

 

Then he put the corally oil on the rheometer and measured them twice as usual.
One value in the range was off compared to whole line of steps.
He has compared the values to the Losi oils already measured before.

* The value 15 Weights we measured was like water thickness and is probably a filling fault at the factory.
Altough the contents was silicone oil it was to thin for the 15 WT specs and can not be used for the shocks.
Associated oils were provided by Kendall Bennet from A-mainhobbies and Tony Penzincka from Tony Screws

*T he cyan colored values collum are provided by Kurt Menger from Team Assosiated R&D and are the values that will be curerntly mentioned on the bottles to give comparising with cSt values. (18-10-2007)

Currently we are measuring our oils with a RHEOMETER.
A sample of such a machine can be found here

This device is able to measure more accurat regardless the viscosity.
 

From September 2006 we measure all oils with a RHEOMETER.


SILICONE SHOCK OIL AND TEMPERATURE

Although everybody thinks silicone oil is not affected by temperature, we can wake you up out of that dream. 
When the same test is done @ 10 or @ 30 degrees Celsius we get other values!
Test result from our laboratory provid us with the following fist rule:

Below some examples.
