Bulk Engine Oil Supplier for UK Workshops and Fleets
Britannia Automotive & Hydraulic Lubricants Ltd supplies bulk engine oil in 20 litre drums, 205 litre barrels, IBCs and full pallets to workshops, fleet operators, dealerships, factors and resellers across the United Kingdom and internationally.
Bulk Engine Oil Supply
Volume Engine Oil Supply for Businesses That Buy by the Barrel
Britannia supplies bulk engine oil to businesses whose consumption is measured in drums and pallets rather than litres. Independent garages, fast-fit centres, dealer groups, HGV and van fleets, plant operators, marine engineers and motor factors all buy from us on trade terms, with pricing set against volume and product mix.
The range covers passenger car and light commercial oils from 0W-20 through to 20W-50, heavy-duty diesel engine oils, motorcycle and small-engine oils, and low-SAPS formulations for modern after-treatment systems. Current stock is listed on our engine oils category, within the wider automotive lubricants range.
We stock from established manufacturers including Castrol, Shell, Mobil, Valvoline, Liqui Moly, Petronas, TotalEnergies and Bardahl, so a workshop can standardise on one brand or mix lines across a single order. If you also buy hydraulic fluid in volume, see our wholesale hydraulic oil page.
Grades and Specifications
Bulk Engine Oil Grades and Specifications We Stock
Viscosity alone does not make an oil suitable. Modern engines are specified against ACEA sequences, API service categories and manufacturer approvals, and getting those wrong can invalidate a warranty.
Full Synthetic
Low-viscosity synthetic grades for modern petrol, diesel and hybrid engines running extended drain intervals and tight OEM approvals.
View engine oils →Heavy-Duty Diesel
Fleet grades for HGV, bus, plant and agricultural diesel engines, including low-SAPS formulations for DPF and SCR after-treatment.
View automotive range →Motorcycle & Small Engine
Wet-clutch compatible four-stroke oils, two-stroke oils and small-engine grades for dealers, hire fleets and groundcare workshops.
View motorcycle oils →Marine & Plant
Medium and high-speed diesel engine oils for workboats, commercial vessels and static plant running long duty cycles.

Industrial range →How We Supply
From Specification to Delivery
A four-stage process for bulk engine oil orders, designed around workshop and fleet buying rather than retail checkout.
Specify
Send the grades and approvals you work to, or a list of the vehicles and engines in service, and we will confirm suitable products.
Quote
We price bulk engine oil against volume, pack size and delivery location, and confirm live stock position and lead time in writing.
Supply
Orders ship in 5 and 20 litre packs, 205 litre barrels, IBCs or mixed pallets, with data sheets included.
Repeat
Agreed pricing can be held across a period with scheduled call-off, keeping servicing supplied without overstocking.
Getting the Cost per Service Right
For a busy workshop the meaningful number is not the price of a drum, it is the cost per oil change once wastage, decanting losses and stockouts are accounted for. Buying bulk engine oil in the right pack size for your actual throughput usually saves more than switching brand.
A site turning over two or three services a day is generally better on 205 litre barrels with a metered dispensing setup than on repeated 20 litre packs. A mixed fleet running several approvals may be better consolidating onto fewer, broader-specification grades. We are happy to look at a service schedule and say which of those applies.
Dispensing equipment, pumps, meters and reels are available through our lubrication equipment range, and coolant, brake fluid and screenwash can be added to the same order from the coolants and brake fluids categories.
