In 1896 they built lamp start oil engines.  By 1912 they had developed a new internal combustion engine that ran on vaporising oil and was fired by a spark. It did not need a hot bulb like most engines of the time. By 1919 they had mounted a 25 hp 3-cylinder version in a crawler tractor, which they built till 1925.
By 1929 they were building diesel engines for the Agricultural & General Engineers (AGE) group. Richard Garrett & Sons assembled some of these tractors. They were similar to an International 15/30. AGE collapsed in 1932.
Associated British Oil Engine Company
The Associated British Oil Engine Company (ABOE) was a British engineering company. In 1945 Mirrlees, Bickerton and Day joined the group.
Mirrlees Blackstone Limited
Mirrlees Blackstone Limited was formed on June 1, 1969 by the merger of Mirrlees National Limited (formerly Mirrlees, Bickerton and Day) and Blackstone & Company Limited. All were, at the time, members of the Hawker Siddeley Group.
In 1988, General Electric Company plc merged its Paxman (engines), Ruston and Mirrlees Blackstone diesels businesses with the Alsthom division of Compagnie Générale d'Electricité (CGE) to form GEC-Alsthom. In 2000, Alstom sold its diesel engine businesses (Ruston, Paxman, and Mirrlees Blackstone) to MAN Group.
Mirrlees Blackstone were bought by MAN Diesel, along with the diesel businesses of the collapsed GEC, although little remains. The Stockport factory has been partly demolished and replaced with a new office and warehouse facility which still serves the aftermarket for spares and servicing of Lister Blackstone engines under the MAN Diesel & Turbo tagline. The Blackstone name lives on with the Blackstones F.C..

British Rail products
Blackstone supplied a number of diesel engines for British Rail locomotives but these were largely unsuccessful and were not adopted.
- In the 1980s, four of the well-established Paxman Valenta-engined HST trainset power cars were re-engined with Mirrlees Blackstone MB190 engines for trials. These were unsuccessful and Valenta engines were reinstalled. Eventually, in the 2000s, the fleet was re-engined with MTU V16 4000 engines.
- The handful of British Rail Class D3/5 used the Blackstone ER6T
- The Class 10 was a small number (150 vs 900) of the widespread Class 08 0-6-0 diesel-electric shunter, in which a Blackstone ER6T engine was fitted instead an English Electric 6KT. They were withdrawn early.
- Class 31 Type 2 locomotives were built with a Mirrlees Blackstone JVS12T but all were rebuilt with the English Electric 12SVT, as used in the Class 37.
- The projected Type 3 freight Class 38 of the 1980s was considered for use of a Mirrlees MB275T. Four of the refurbished Class 37/9 at this period were rebuilt with the engine as a trial, two more used the Ruston RK270T as a comparison. In the end, the Class 38 was cancelled in favour of the Class 60.
- Class 60 heavy freight Type 5 locomotives of the 1980s replaced the projected Class 38. Like the 38, these used the Mirrlees MB275T engine. (Contract of 109 MB275 engines received by Mirrlees). These 8 cylinder engines, compared to the more common V12 or V16 engines in this power range, were hoped to show lower operating costs owing to their simplicity.
The Stamford East railway station serviced the companies works.
- John (Jack) Henry Pick who was the founder of The Pick Motor Company previously worked for Blackstones.
- Harry Watson (OBE), Managing Director, Mirrlees Blackstone (Stockport) Ltd; Managing Director, Mirrlees Blackstone (Stamford) Ltd. He was mentioned in The Queen 1991 Birthday Honours list.
Examples of Blackstone engines can be seen at the Anson Engine Museum near Manchester. The former Stamford Museum in Stamford, Lincolnshire, also had a Blackstone engine on display, and held an archive relating to the company.
