Had to look them up!
They profess to be for greater sealing than copper or aluminium.
Can't say I've ever had an issue with copper or aluminium washers and I can re-anneal those and use again and again.
They'd have to be super cheap to make me change.

Guys, if a manufacturer states a Dowty washer over a conventional copper/alloy washer, there's a reason for it. This is normally due to system pressure, Dowty washers are very good at sealing at higher pressures. On our Landies, Dowty washers are used on the high pressure side of the power steering pumps...but not on engine/gearbox sumps as these are low pressure.

Agreed, they do different jobs. Stay with the spec.

Not always true. Who the hell would be daft enough to use plastic dowels to locate a cylinder head?
Amen ....
If a Dowty will stop the leak, and it'll take the pain ( I.E. not really any use as an injector sealing washer
), then carry on 
We used to use 18mm Dowty washers on the sump plugs as a matter of course when I worked at a Citroën main dealer, as they were specified by PSA.
I continue use them on other similar applications.
