Default converting Xray CST oil values to Mugen Wt oil

Hi, i have recently purchased an mtx5 after owning an nt1. i have a bugger load of xray CST diff oil. does anyone know what the xray cst diff oils are equivalent to in the mugen Wt?

i have found this link:
http://www.rctech.net/forum/nitro-of...rt-wt-cst.html

but it seems to be mainly covering shock oil ranges.

I've always thought that the Mugen and Xrays oil where both listed is CST ratings

Yes... "Rated" is one thing. "True" CST is another.

Test a 100k Diff Mugen vs a 100k Diff Xray to see what I mean.

I've never done that test. Maybe I will. I always assumed that CST was CST no matter what brand.

so mugen oils are in CST?? i always thought they were in wt measurements.

all good then. there is a definate difference between mugen 100,000 and xray 100,000 i think the xray oils are "thinner" so to say.

If you follow one of the links above. The twf8 chart says that Mugen and Xrays oils are listed in "linear CST ratings".

But I've never compared them side by side. I don't go by the feel method. I've found that there many more variables associated with a differential when you spin it in your hand. ie orings on the outdrives, and how much fluid you put in the diff. I only go by how the car feels on the track.

They may be linear, but with different "slopes" and "intercepts"...

Possible???

I would think if you ploted both lines on a chart with same cst rating and both lines are linear they would fall on top of each other.

You have used up all of my available brains cells for this week. We can finish this next week.

Shock Oil CPS vs. WT



Old Xray:
Rated ... cSt
300........354
350........381
400........441
450........475
500........542
600........625
700........702
800........799


As you can see, they are both rated the same, but actual CST differs from brand-to-brand. They are quite some actual jumps (exponential IMO) when it comes to diff oils. That is why Mugen 100k is the heaviest they make, because it feels like 200k-300k of other brands.

I just advise to stick with one brand, be it XRAY, Xceed or Capricorn because they offer a good range of oils.
