See Homepage. This page: A leaflet issued in the 1950s by Brown Brothers, describing the range of Dextrol motor oils.

Dextrol Oils.

Brown Brothers Ltd and Thomson & Brown Brothers Ltd were the sole UK distributors for Dextrol Motor and Tractor Oils in the 1950s, a brand that has long since disappeared from the shelves, in the UK at least. Whether Dextrol, itself part of The Neasden Oil Company Ltd, was simply re-named in later years, withdrawn from sale in the UK, or perhaps sold in its entirety to another lubricant manufacturer, I'm not sure, as information on this company seems to be thin on the ground.

Fold out the leaflet and the sheet has two sections, one outlining the grades and prices for their oils, the second listing popular applications. Various grades of oil were offered:
Oils leaflet
  • C - Motor Oil SAE 20, 30, 40
  • T - Tractor Oil SAE 20, 30, 40
  • DT - Detergent Diesel Oil SAE 20, 30
  • G - Gear Oil SAE 90, 140
  • DEX-P Extreme Pressure Gear Oil SAE 90, 140
Popular commercial vehicle applications for Dextrol oils are given. The list of mostly UK makers is a gloomy reminder of just how many British commercial vehicle manufacturers have disappeared from the roads since the 1950s:
