A while ago, people asked about what oil to use in armstrong lever arm
shocks.
I spoke to the guys from SG Leslie & Sons, a local armstrong shock repair/
rebuilder. He said he makes up the oil these days with simple hydraulic oil
and some oil additives. He told me that I could either
a) buy a 5 litre container (what he sells normally)
b) bring down a 1 litre bottle and he'll fill it for a big markup
or
c) buy Penrite Auto transmission Fluid, which has all the same additives
(he said almost exactly the same). I told him it was for a race car
and he said no problems.
I personally have found it difficult to find 30wt motorcycle fork oil, most
modern bikes using weights around 5.
>From what I gathered, mostly the additives are there to prevent foaming and
to ensure little change in properties with high temperature.
Hope this helps,
Mike
