Halfords won't have anything suitable.
ISO 32 hydraulic oil with anti-wear additives for everything except the slideways. Thats a basic hydraulic oil readily available mail order or from specialists. I use Castrol Hyspin AWS 32 in my (not Myford) lathe 'cos its what I can get easily and its done me fine for over 25 years but there are many equivalents from other brands. No need to pay extra for the fancy high temperature, anti-foam et al properties.
ISO 68 dual rated slideway / bearing oil for the ways and backgear train. Pukka way oil is too sticky for small lathes. Many brands but I use Castrol Magna BD 68. Excellent in the oil can for hinges and the "Honey Do" jobs too. Thin enough to flow (slowly) but stick enough to stay put for a year or more. But not in locks!
