Caldo Oils Limited started life as the Caledonian Oil Company in March 1922 blending lubricants for the fledgeling motor industry.

The Scott family had been in business as Iron Founders and Engineers in St.Helens from the early part of the 19th Century. In 1922 the Scott brothers Austin, Leo, George Walter and John started The Caledonian Oil Company, however, early on, Austin, Leo and George decided to sell their shares to Walter and John for the sum of £50.00 each.

The Company prospered and expanded into the fuels business buying from companies like Anglo-American Oil Co., (Esso), Texas Oil Co., (Texaco), Petrofina (TotalFinaElf) and Russian Oil Products. Buying petrol for 1/- per gallon. This continued until the outbreak of the war in 1939, when the companies tankers were commandeered by the Petroleum Pool Board in London.

After the war, business continued growing with expansions into the petrol retailing business and, in 1951, the Caledonian Oil Company became Caldo Oils Limited.

The Caldo Group is now a large diverse business, with Printing and Plastic Card production, alongside the Lubricant Blending, Contract Packing, Fuel Distribution and Petrol Station business.

The Group is still run by the Scott family with Philip, (Walter's son), as Chairman. The current generation are Michael, as Managing Director of Caldo Oils Limited, (wholesale Fuels and Lubricants), and Timothy the Managing Director of Caldo Forecourts Limited (Petrol Stations and Printing).
