The pink/orange OAT long-life stuff is the way to go. Halfords sell their own brand in concentrate or 50:50 mix. Unless Halfords have a sale on, I buy mine from a local motor factors. Comma branded and half the price although I buy concentrate and dilute it 50:50 with the condensate from the tumble dryer as you're actually paying a lot for plain water in ready mix.
