1 It may help to measure out the quantity of oil required into a clean jug or rely on the markers on the side of the oil container. Use a clean funnel to help pour the oil into the engine, usually via the filler neck in the rocker/ camshaft cover. Pour slowly to avoid spills.
2 After pouring the recommended quantity into the engine, extract the dipstick, wipe it, re-dip and check the level. Look for ‘MIN’ and ‘MAX’ markers. For a turbo engine, the level should be halfway between them. For most nonturbo engines, nearer ‘MAX’ is recommended, but confirm this in your workshop manual.
3 If an engine doesn’t have an oil dipstick, you may need to switch on the ignition and look through the dashboard menu settings to check the oil level. On some vehicles, the ignition must remain off for 15 minutes before the oil level can be checked.
4 After checking and, if necessary, topping up the oil, run the engine and make sure any oil pressure warning lights do not remain illuminated on the dashboard. Switch off the engine after a few seconds, then look underneath for any leaks. Wait a few minutes or more before checking the level again – it may need topping up.
