What kind of water in my Aston?
Discussion
Following on in a similar vein from the “which oil” threads it made me wonder if perhaps we should examine manufacturers guidelines in more depth.
Reading my handbook it recommends that I top up my screen wash/coolant, etc diluted with distilled water. What it doesn’t make clear is what temperature the water should be distilled at. Obviously if I distil the water at sea level it will boil at a higher temperature than if I boil it at home which is 2-300 feet above sea level. Also, does it matter what temperature the water condenses at?, as this can vary greatly depending on ambient temp and temp differential. Steam from my shower (at 50 deg) condenses on my bathroom window at 20 degrees for example. (going o/t a bit but could I collect this and use it?)
Does it matter what type of water I start with, is good fresh Northern water which has bubbled through the earth for millennia before bursting forth in a fresh mountain spring better than the many times recycled sewage which Londoners have to drink?
Also is plain old H2O ok or would I be better with one of the other isotopes of water, obviously you don’t want to use 2H2O which being heavy water would upset the perfect 50/50 balance on my DB9. As you can see from the table below these isotopes all have different densities and viscosities at different temperature and pressure which could put undue strain on the water pump.
I’ve seen a product for sale called dehydrated water, http://www.buydehydratedwater.com/ has anyone used it?
I know I could buy ready mixed screen wash or coolant but how can you trust the manufactures or their employees?. For all we know they could be using rainwater* they’ve collected in a water butt off the drainpipe or even tap water!!! I daren’t risk it.
Obviously I don’t know what been used before as my car was serviced at a garage and god knows what they use, probably just piss in the header tank and then wipe round with an oily rag, do you think I could tell what they’ve used by listening to the flow around the engine – perhaps with a stethoscope?
Perhaps we could discuss this at length for a few pages or perhaps it doesn’t matter at all and I could go with what the manufacturer recommends and leave it to the trained mechanics to worry about on my next service?.

- I know rain water has been distilled from the Ocean but I don’t think this counts.

PS Just remembered you are on the Wales run post Geneva..so I will expect this to be discussed further along with the long awaited explaination about Louisa, the World Cup and a couple of 'other' things

You've missed the obvious - its not the viscosity of the water that should be your big worry, its the additives. What screen washer additive do you use? I've used Halfords stuff in the past but worried its too cheap and not Aston enough? Can I use fairy liquid as a stop gap?
What if I dilute the screen wash with more screen wash, does this double the strength and get my screen and lights twice as clean or do I only have to squirt half as much? I've found fairy liquid can be a bit harsh and strips the wax off the freshly Polished paintwork, Persil seems to be much kinder.
