Granville Oil & Chemicals is a UK-based manufacturer focused on supplying high-quality lubricants and automotive chemicals for real-world maintenance and repair. The brand’s range is built to cover everyday servicing needs—spanning engine oils, manual transmission fluids, and a variety of ancillary lubricants—alongside a strong line-up of workshop and bodyshop essentials.  Beyond fluids, Granville produces practical problem-solvers designed to help technicians and capable DIY users keep vehicles running cleanly and reliably. Examples include fast-drying Mass Air Flow (MAF) sensor cleaner to remove deposits from MAF sensors, fuel-resistant epoxy repair putty for durable repairs on metal components, and brushable seam sealer to protect joints and seams against ingress of water, chemicals and oils—ideal for bodywork and panel applications.  Granville also covers specialist maintenance items such as Red Rubber Grease for environments requiring seal compatibility and hydrocarbon resistance, plus broader-use products like belt dressing, hydraulic jack oil, and chainsaw oil—making the brand a solid “one-supplier” option across garages, workshops, and trade counters.
