Whether you are carrying out a full service or topping up between oil changes, using the correct 5W-40 engine oil helps reduce wear, protect components under load and keep your engine running efficiently for longer. This grade is thin enough to circulate quickly on a cold morning, and thick enough to keep protecting components under heat and load. If your vehicle calls for the thinner grade, browse our 5W-30 engine oil range instead. The grades are not interchangeable, so always check your owner's handbook or use our registration lookup before ordering.

Our range covers both 5W-40 fully synthetic oil and semi-synthetic formulations to suit different engines and budgets. Fully synthetic oil is the usual recommendation for modern engines with tighter tolerances, diesel particulate filters, and extended service intervals, offering stronger protection against wear and thermal breakdown. Semi-synthetic options provide reliable everyday protection at a lower price. 

Choose a 1-litre bottle for topping up between services, a 5-litre container for a complete oil change, or a 20-litre drum if you are servicing more than one vehicle. Our stock covers leading brands including Castrol, Shell, Comma, Mobil, Liqui Moly, FUCHS, Granville, and Valvoline.

Buy 5W-40 oil at FIXRA today, with free delivery on orders over £20 and next-day delivery options available. Our 60-day returns policy and Click & Collect make ordering simple from start to finish.
