G'day all,
I do a lot of small motor repair and I run some old British machinery with Oilite bushes and white metal bearings. The recommended lubricants for these are Hydraulic fluids with ISO between 32 & 100 depending on the bearing.
The motor bearings are generally recommended to use Royal Purple Synfilm 68. The only problem I have is in Australia it is only available in 5Gal qty and only in multiples of more than one container (thus making it effectively unobtanium and certainly unaffordable).
The predominant quality required of all of these fluids is long term oxidation stability. They are all open bearings and really need a fluid that will be stable long-term. None of these machines are particularly high load or run at high temperatures.
The only synthetic lubricants I appear to have access to are Amsoil Compressor oil, and then only in 46 & 100 grades. Being designed for compressors I'd have thought it'd need to be extremely resistant to oxidation. Could I mix the 46 & 100 to come out with something like a 68? Would Amsoil Compressor oil in this use case come anywhere near the RP Synfilm for longevity?
My lathe specs ISO 32, but i figure 46 might be close enough for the light use it sees.
Us Aussies are pretty jealous of the range and pricing you guys get.
