Chemicals in tap Water.

[ZR1cliff]

Ive always topped up my anti freeze with tap water but have recently been advised to use distilled water because of the chemicals found in tap water,is tap water really that bad?,any chemists here that can throw some light on this.

You see all that stuff that grows in the kettle. Do you want that blocking up the waterways in the engine block/radiator....

What do you drive? I'd be worried if I had to put as much water through my car as I would a kettle!

[Incorrigible]

Most modern cars use a pre mix system

IMHO to make more money out of us but I'm a cynical git

Are you sure you should be topping it up with water ???

[Parrot of doom]

I wouldn't worry about it personally, a kettle sees far more water than a car's cooling system ever will.

My mk1 mr2 used 1 liter of oil and 1 liter of coolant to get between Amersham and Castle Combe. Where the engine expired....
