Do UK petrol stations sell engine oil?

Yes, most UK petrol stations sell engine oil alongside other car maintenance products.

When topping up engine oil, it's crucial to maintain the correct level between the minimum and maximum marks on the dipstick. Overfilling can cause several issues:

1. Increased fuel consumption: Excess oil increases engine temperature and pressure, creating more resistance that reduces performance and increases fuel usage in popular UK models like the Vauxhall Corsa or Ford Focus.

1. Potential leaks: Too much oil raises crankcase pressure, which may force oil past seals and gaskets - a particular concern for older vehicles common on British roads.

1. Cooling problems: The correct oil level is essential for proper engine cooling, especially important for performance models like the BMW 3 Series or Range Rover.

For UK drivers, major supermarket petrol stations (BP, Shell, Esso) typically stock a range of engine oils suitable for different vehicles, from small city cars to larger SUVs. Always check your vehicle handbook for the correct oil specification before purchasing.
