A slightly thicker oil at operating temperature, 10W-40 engine oil helps maintain oil pressure and reduce consumption in older petrol and diesel engines, and for higher-mileage vehicles where a thicker oil helps maintain pressure. Newer cars generally call for thinner grades such as 5W-30 or 0W-20, so check your owner's handbook or use our registration lookup before ordering.

This grade is also common in four-stroke motorcycles, where a single oil lubricates the engine, gearbox and wet clutch. Our range includes dedicated 4T 10W-40 motorcycle oil formulated to a JASO MA specification, alongside our car and light commercial options.

Most 10W-40 on the market is semi-synthetic, blending mineral and synthetic base oils to give dependable everyday protection at a sensible price. We also stock fully synthetic 10W-40 for engines that benefit from improved thermal stability and longer intervals between changes. You can compare the fully synthetic and semi-synthetic engine oil range if you are weighing up formulations.

Shop 10W-40 engine oil at FIXRA with free delivery on orders over £20 and next-day delivery options available. With a 60-day returns policy and Click & Collect options, keeping your vehicle serviced is straightforward.
