Damping fluid for fuel guage

[Bozo]

I know this topic has been on a few times. I bought some damping Dimethicones oil for the fuel gauge but my gauge still doesn't work correctly (bounces). Are there different viscosity oils if so which one should we use and maybe a hint on where I can get it from?

Whatever you find, be sure to add it here:

latest, last night I took the gauge out again but this time I drilled a 0.7mm hole below the larger hole and with a syringe I forced the dimethicone (through the larger hole) till all the air was purged out of the housing. On the way to work this morning the gauge behaved perfectly apart from a very "small" amount of movement. Fixed

Bozo, what you are looking for is silicone oil that is available at hobby shops,
It is used in RC car/truck gear cases. and I hear also RC shocks?
Yes it is available in different WTG, as for which ..not sure.

Thanks Tony, I bought some RC silicone oil 300,000 rating (I hope its thicker), there are lots of viscosities with weird ratings, even though my gauges work 90% better they still have a small bounce which I'm determined to eliminate. I'll let you know how it goes.

I can't remember why the rc diff oils are rated in the 000.0000 but same as most things, the higher the number the thicker, shock oils are easier to follow, 10 is thin, 50 is thicker ect,

Bozo sorry should of jumped in before about this I have a faint memory of doing this 10 odd yrs ago, Toyota supply an oil can't remember part number but its gauge oil used it on my speedo worked a treat, it comes in a small tube with about 10mls, if what you used doesn't work try that

I'm wondering if you are talking about the oil they use in pneumatic fans (sold in 10ml see through tubes), it is a sticky oil, until about six months ago I had two tubes. If the RC oil turns out to be crap I'll get a tube you suggested.
Thanks Baldy

Yes it was oil they used in fans if I recall and it was only about 10mls and red too I think

Baldy, I got some and it looks thicker (obviously better) then the Dimethicone, it is a 18ml tube, for the technically minded it is 10,000Cst rating. Toyota part number 08816-10001. I'll be trying it this weekend and post my results.

Thanks for the heads up Baldy.

Baldy filled the gauge today, here is a photo of the silicone oil I used

There are also some photos of the items used to fill the unit. I hope to ride the bike tomorrow and let you know how it goes.

No probs Bozo I think its the same stuff it was used to lubricate some fan on the Toyota and was a very heavy oil

Baldy, the gauge was fantastic (no I didn't glue the needle to the face) the needle was steady as.
Thankyou to all that helped me with this (even Arnie who helped in the background).
Tony, thankyou for pointing out RC oils, now we know that the rating is 10,000Cst we should be able to do either. I did try a couple of extra things to make this work -
1. I added a small hole below the bigger fill hole to expel the air as the oil was added - slowly
2. Obviously the higher viscosity oil.
3. Before the oil I used a vacuum pump to pump out any crappy leftover oil (don't forget I used thinner oil previously)
4. Selastic would leak after a while, so I used a hot glue gun (only time will tell if this worked)
