One of the most commonly used engine oils alongside 5w30, 5w40 oil is designed to deliver outstanding protection and efficiency across a variety of driving conditions. It flows easily at cold temperatures for quick lubrication and maintains its performance even under heavy loads or high heat, making it an incredibly versatile oil. 
We only stock oils that we trust from reputable manufacturers, such as Castrol, Fuchs, and Shell, so you can buy with confidence. The 5w40 oils we stock can generally be used in cars, vans, and LGVs. If your van or light goods vehicle handbook recommends using 5w40 oil, the products you can choose from will be roughly the same as if you had a car.
With so many options to browse, from 5w40 fully synthetic oil to semi-synthetic options, choosing the correct oil can feel overwhelming – but that’s where we come in! Use our handy registration plate tool above, or get in touch with our team of experts for personalised advice and recommendations.
