Thinning Silicone Oil

[agnotheist]

Hi! Can I thin 1000cst Silicone Oil to achieve lower CSTs? Targets are 550 and 350. A local company's selling 1000csts by bulk and I wanted to take advantage of it.

Thanks in advance.

You can thin silicone with lower viscosity silicone using a mixing calculator but you'd be better off just buying some Team Associated 30wt (350sct) or 45w (575cst) if that's the viscosity you're going for. If you buy the 1000 in bulk you'll still have to buy a super thin cst silicone to cut it with.

Thanks for the reponse! I'm from the Philippines. RC specific oil gets a bit expensive in LHSes here and I would be able to save around 60% of the cost if I get in bulk (100 and 1000 cst). Can you tell me where to find that calculator?

I have a Kraton so I would really need 1000cst.

This is the one I use to mix my own cst

Purchase a syringe that holds around 10-12 ml and draw in the desired ratio of both, then cycle the syringe to mix the two together

You, mister, are awesome! Thank you so much!

I have that one saved too. The only thing is in the 2nd calculator where it says "desired viscosity" you can only ener 4 digits.

In another post about this someone else posted another calculator I saved and use for that.

I love stuff like this. And this calculator is exactly what I need. You may've put this up before and I think I sent to my dad...he loves stuff like this too and will plug in anything to see it work.

I'd like to work with weight here but not sure if it's set up like that. Or I don't know how. I want to use a <gram scale.

edit: what I mean is rather than measure in volume, I'd rather measure in weight (not weight of the fluid as it's categorized.) Not sure how this all translates but pretty cool to think about.

The 1st calculator on the page is good up to 9,999,999cst. You just have to move the percentage for #1 around until you get to the desired cst rating you're after. I use the 1st calculator for my center diff fluid and the second for all the other fluids

Im gonna crash this thread... Does anyone know if mixing very different viscosities will work? Say, I bought some Trackstar 100k cst for my Kraton's center diff and would like to mix it with AE 80wt (~1000cst) shock oil to get something in the 10-50k range for the front and rear diffs.

it should. Silicon Oil is Silicon Oil, from what I have been able to ascertain on the quantities of additives used to vary the thickness vary and in terms of those there doesn't seem to be a lot of variation in the chemicals used. Therefor a given weight between manufacturers may have some slight variation, but I can't see how this would be noticeable to a basher. Serious guys on the track will be looking for consistency above all else hence they will stick rigidly to one brand.
