Does anyone know what the self life should be for Haldex oil. I was surprised I must admit how old it was, must have done my car in 2012 so that is what it was dated, I assume manufacture date rather than use by. When I opened it up and started to pour the first bit was watrry then remainder a bit on the lumpy side. Anyone know if this is normal, I haven't thrown it away yet so I suppose can it be rectified/used or should I just chuck it? I bought a new one for the Wife's car and have done the job so when I will need another bottle, who knows, just hate throwing unused things away.
