Running low on engine oil is one of the most avoidable causes of serious engine damage. Checking your oil level takes about two minutes and should be done at least once a month and before any long journey.
What you need
A clean cloth or piece of kitchen roll. That is it. The dipstick is already in your engine.
How to check the oil level correctly
Park on a level surface and turn the engine off. Wait at least 5 minutes for the oil to drain back into the sump. Open the bonnet and locate the dipstick (usually a brightly coloured handle, labelled OIL). Pull the dipstick fully out and wipe it clean. Reinsert it fully, then pull it out again. Hold it horizontally and read the level against the two marks at the end. The oil level should be somewhere between the minimum and maximum marks, ideally closer to the upper mark.
How to top up the oil
If the level is at or below the minimum mark, add oil. The filler cap is on top of the engine, usually marked with an oil can symbol. Add small amounts at a time, checking the dipstick after each addition. It is easy to overfill. Do not fill above the maximum mark.
Which oil should you use
Use only the oil grade specified in your vehicle handbook. Common grades include 5W-30 and 5W-40, but your car may require something different. The specification (such as VW 504.00 or BMW Longlife-04) matters as much as the viscosity grade for newer vehicles.
What if the oil is very dark or smells burnt
Engine oil darkens with use. Some darkening is normal. But if the oil is very thick and black and your car is due a service, that is a sign the oil change is overdue. Fresh oil ranges from golden amber to light brown.
What if you have to top up frequently
If you are adding oil regularly between services, that is not normal. It could indicate a leak (look for oil spots under your car) or that your engine is burning oil internally. Both should be investigated. Call us on 0131 554 3423 or contact us here.
