LawrenceR Posted November 13, 2010 Share Posted November 13, 2010 Hello POBC, I am sure I being a cheap skate but I don't like to throw stuff away so I ask the following: How long would an unopened plastic bottle of Castrol Super response Dot 4 lasts? I have about a 1.5 l which is two years old, the opened 1/2l is of no use i am sure but I am wondering about the un opened one. I am also wondering if it is possible to drive any water off by heating it? Any thought welcome including "Stop being tight" and "why risk your brakes they are far too important" Thumbs Link to comment Share on other sites More sharing options...
skydragon Posted November 13, 2010 Share Posted November 13, 2010 If it's unopened and only 2 years old, it should be just fine. Dispose of the 1/2 litre which you,ve previously opened Link to comment Share on other sites More sharing options...

Mavic82 Posted November 13, 2010 Share Posted November 13, 2010 I would think it should be OK as long as it was not stored on a concrete floor. The moisture will permiatate the bottle over time. Would not advise heating it, either use or chuck away. Remember the ignition temp is quite low compared to petrol for example Link to comment Share on other sites More sharing options...
skydragon Posted November 13, 2010 Share Posted November 13, 2010 To flush the system through and bleed i belive 1.5 litres should do it. Btw brake fluidvis not really something to skimp on.... Not just from a safety/performance perspective, but because if the moisture content is too high it can cause corrosion, which in turn will cost you lots ££ Link to comment Share on other sites More sharing options...
