and yes Paco's site is a very good place for info!

You're missing the fact that WT has no relation to CPS. AE shock oil is in non-linear values that are totally different than CPS.

For example: Going by Paco's site, Xray 60,000 oil is about 65,000 cps and 10,000 oil is 13,000 cps. To acheive 35,000 cps, you would use 33% of the 60k oil and 67% 10k oil. However, if you assumed that Xray oil was EXACT and 60k was 60,000 cps and 10k was 10,000 cps, then you would use 30% and 70%.

You cannot relate WT to CPS in any way. That calculator is designed for CPS only.


Another example is to check out the values Paco tested for trinity oil. 40 Wt was 505 cps. BUT 45 Wt was 497 cps. Thus the values of the Wt system is in no way precise or linear at all...

Logically speaking a 40 w should lighter than a 45w oil. The fact the the true numbers are all over the place enforces why people buy one brand and use weights within that brand. Using the blender should give you the desired effect your looking for. Like anything the more precise the oils you use the more accurate the blend becomes.

No I'm not missing that fact at all. I fully understand what you are saying. Wt & Cps are not the same and I agree.

For example: Going by Paco's site, Xray 60,000 oil is about 65,000 cps and 10,000 oil is 13,000 cps. To acheive 35,000 cps, you would use 33% of the 60k oil and 67% 10k oil. However, if you assumed that Xray oil was EXACT and 60k was 60,000 cps and 10k was 10,000 cps, then you would use 30% and 70%.

You cannot relate WT to CPS in any way. That calculator is designed for CPS only.

How did you find this out? I went back and searched the entire site and could not find this info. All that calculator says is that is a fluid blender and asks for fluid viscosity which to me means any fluid with a different viscosity.

For example I realize that Mugen 5000wt & 3000wt might not be 5000cps & 3000cps or anywhere close. But if I am used to running 5000wt or 3000wt and I know how they both feel on the track and I want something in between like 4000wt weather it is excactly 4000wt or not it is still in between 5000wt & 3000wt.

I am not saying that fluid blender works perfect for what most of us are using it for. All Im saying is that it gets us close enough for what we are doing.

o.k.. how to blend the oil.. using blender..?? or just enough soak it in a bowl/bottle.. or just put it in the diff case and let the diff gear mix it....??

I understand what you are saying now and I take that back about it being CPS only. As long as you use a precise linear unit of measurement for fluid viscosity it will work. However, WT is not a precise or linear unit of measurement.

By using the calculator with WT measurements, it will result in an accurate, but NOT precise result. For example, if you mixed 3000 wt. and 5000 wt. using the calculator, you will result in a mix somewhere between the two, but there would be no way to know what the result would be. For diff uses, it should be fine enough for the average person. But for shocks, you would need to be much more precise.

Fair enough!

I have really only used that calculator one time. It was about two years ago. I wanted to try 6000 in the center and Mugen does not make 6000. I didn't like doing it that way because for one I wasn't really sure I had mixed perfect for 6000 and two if I did like the way it felt on the track I probably couldn't mix it the same everytime. Now I just use the Kyosho 6000wt. Kinda strange that Mugen makes 2000 & 4000 but not 6000 & a lot of people don't even know they make 2 & 4.

Is it possible that the blender is taking into account the non-linear values of WT oils? I ask because I wanted Associated 32.5, which I've been making for quite some time with 50-50 blend of 35wt and 30wt. Out of curiosity I plugged in the values, and it said something not quite 50-50. It was something like 52.5 of one and 47.5 of the other.
