Ian - If you concede that there can be a difference of possibly weeks/months between A and B, is it not appropriate for one to suggest A is longer lasting than B if that is the question the OP posed? When each 1L of chemistry might cost a dollar or so, a month can matter and be akin to tossing $1 down the drain. If one can prevent wasting a dollar, a dollar saved is....
Fwiw OP, I am a Liquidol user, I don't print frequently, I mixed up 1L this summer and printed maybe 3 sheets in it, then bottled it up and have not been able to print till yesterday, it worked just perfect.

Andy, my point is that all the PQ developers I've used have had a shelf life in exceess of the OP's 2 years, there's little point in the deliberate posts by some that deride formulae that have beenin use for around 60 years.
You also have to discount comments from people with a commercial interest in their own product.
