Awsome video mate very precise info in a short no nonsense way. The piece of glass was a fantastic touch for demonstrating the oils. I can move forward with my build now cheers and keep the content coming
I would try anything on hand. You don’t need the additive package in motor oils but it shouldn’t hurt. IIRC Bar Oil for chainsaws is detergent free. Air compressor oil is also additive free. I’m using some Ballistol because I like the smell. Stay away from natural food grade oils as they oxidize and become gummy. Most oils are mineral oil based but raw mineral oil from the pharmacy section of the store is very thin. Another comment says don’t use motor oil with multiple numbers which indicate the cold and hot weighs but I don’t think that matters unless your car is going over 100mph. If you’re doing slower driving the oil isn’t getting worked hard enough to get into the high temp range.
Seals made of rubber from petroleum will deteriorate if you use a petroleum based fluid. If the fluid dampening flaps in the shock are made of silicone, petroleum based oil is fine.
You should run straight weight oil's instead of the 10-30 or 10-40. Those 10-xx are all going to behave like 10 weight oil and 20-40 or 20-50 will behave like 20 weight. I use 30 or 40 weight you can find them anywhere but they also have10, 20 and 50, maybe 60 too. If you need heavier you can go with gear oil up to 120 or more. Also it is important to know that temperature will effect the dampening so in high temps you will want heavier or higher numbered oil than you will want in cold temps.
I don't know where these RC oil charts originate from but they bear no relation to engineering charts. As an example your 1000 cst on the acrylic sheet barely moved, and it is equivalent to 80wt on the chart. If you had put 80wt car gear oil on the sheet it would have run down the sheet similar but a bit slower than engine oil. Here is a table on an oil company's website 1000cst is equivalent to 250 gear oil www.crownoil.co.uk/guides/hydraulic-oil-guide/
You pretty much answered all of my questions in regards to engine oils for rc shocks in this video. Thanks for sharing and keep up the good work 👍
Excellent idea showing the oil runnung down the glass. Vaya con Dios
Hi what 10w40 or 75w90 gear oil be roughly compared to cst

Thanks for the informative to the point video. Im gonna get something smooth like you had there and try some of my own oils out in the garage.
Have you tired sunflower oil or baby oil ?
What weight engine oil should be good??
I've got some mineral oil. Could that be any good?
What about transmission fluid
I run 10w 40 in my wltoys 124019 no issues and in my traxxas slash too
What CST is best for light bashing? And what rating of engine oil if not cst.

Do you think silicone brake fluid dot 5 would be ok
Brake fluid is usually corrosive so be careful there
Could you use high vg vape liquid as that has an oil texture
Thanks for the info, can you share the table you were looking. Thank you.

I had some Ballistol in an oiler can so I’m trying it now. Bonus is it smells like an old machine shop.
I tried cooking oil and for short term it seemed ok
So can I use a coconut 🥥 oil ?
You can use KY lube if you like
Please do and let us know how they are
What transmission fluid
Olive oil (extra virgin of course) or sunflower oil here

I used lsd oil from my car to fill my shocks on a wltoys 124017 and they work perfectly

85w140 will that be like 800cst roughly
I have some Singer sewing machine oil lying about somewhere 🤔
Give it a try I would stay away from fully synthetic oils and brake fluids though as some O rings don't like them and will be destroyed
Baby oil and Ann Summers love oil would seem likely candidates!
Baby oil seems like it would work great ,doesn't it!?
