<p>The UK lubricant industry just won its first anti-dumping case — and the man who built the file spent three years gathering the evidence, often alone.In Episode 53 of F+L Webcast, host Vicky Villena-Denton speaks with Mark Lord, founder and Managing Director of Aztec Oils Ltd, about the three-year battle against unfair lubricant trade in the UK that ended in December 2025 with a landmark UK Trade Remedies Authority verdict: a 35% import duty on passenger car motor oil from the United Arab Emirates, and a 90% duty on imports from Lithuania.In this conversation:• How Aztec Oils grew from a 1995 kitchen-table conversation into a 25,000-tonne-a-year UK manufacturer • How Russian base oil rerouted through UAE and Lithuanian blending hubs into the UK after 2022 sanctions • Why one company alone took 15% of the UK PCMO market • How Mark Lord, Morris Lubricants and the UKLA built the case for the Trade Remedies Authority • Why Mark calls the December 2025 verdict &quot;a skirmish, not the war&quot; • Variable quality, REACH-non-compliant additives, and the limits of the VLS testing programme • Why the proliferation of OEM-designer lubricant specifications is making the market harder, not easier</p>
