Why should I check my car’s oil level?

Engine health and reliability

Regular oil checks keep your engine lubricated, which reduces friction and prevents overheating. Low oil can cause serious damage, sometimes leading to engine failure. A 2024 SMMT study found engine issues are a top reason for breakdowns in the UK. Checking your oil could save you hundreds or even thousands of pounds in repairs.

Building trust with customers

At Sandicliffe, we believe in helping drivers stay safe and confident. Promoting awareness of oil checks builds trust and shows we care about your car’s health. We often see customers return for regular maintenance because they know we’re here to support them.

Preventative maintenance trends

Many garages and retailers now offer preventative maintenance packages, often including regular oil checks. These plans help avoid unexpected repairs and keep your car running smoothly.

What tools do I need to check oil in a car?

Essential checklist:

-        Clean rag or paper towel

-        Gloves (optional, but handy)

-        Correct engine oil for your car (check your vehicle handbook)

Many drivers now use do-it-yourself maintenance kits, which include oil, filters, rags and step-by-step instructions. At Sandicliffe, you can order supplies online and use our click and collect service to make things even easier.

How do I prepare my car for an oil check?

Before you start, make sure you’re working safely. Here’s a quick checklist:

-        Park on a flat, level surface

-        Turn off the engine and wait at least 10–15 minutes for it to cool

-        Wear gloves to protect your hands

-        Make sure the ground is clear of clutter

Following these steps helps you get an accurate reading and avoids burns or spills. The Health and Safety Executive (HSE) recommends always letting the engine cool before any checks.

Where is the dipstick and how do I find it?

The oil dipstick is usually a brightly coloured handle (often yellow or orange) near the engine. If you’re unsure, check your vehicle handbook for its location.

Pull the dipstick out completely and wipe it clean with your rag. This prepares it for an accurate reading. Some newer cars use electronic oil sensors instead of dipsticks. Here’s a quick comparison:

If your car only has an electronic sensor, follow the instructions in your vehicle handbook.

How do I check the oil level step by step?

Step-by-step guide

1. Make sure the engine is off and cool (wait 10–15 minutes).

2. Pull out the dipstick and wipe it clean with your rag.

3. Reinsert the dipstick fully, then pull it out again.

4. Look at the oil level:

-        There are two marks—min and max—on the dipstick.

-        The oil should be between these marks.

Interpreting the markings

-        Oil below min: Add oil right away.

-        Oil between min and max: Good to go.

-        Oil above max: Too much oil—seek help from a garage.

If you’re unsure, here’s a simple mini-guide:

-        The min mark is usually a lower notch or line.

-        The max mark is a higher notch or line.

-        If oil is below min, add a small amount (about 100–200 ml), wait a minute, then recheck.

-        Always check your vehicle handbook for exact instructions.

When to seek help

If oil looks dirty, gritty or milky, or if you’re topping up often, it’s best to ask a professional for advice.

When and how should I add oil to my car?

If your oil is below the min mark, it’s time to top up. Here’s how:

1. Find the oil filler cap (usually labelled “oil” or with an oil can symbol).

2. Add a small amount of the correct oil (100–200 ml is typical for most passenger cars).

3. Wait a minute, then recheck the level with the dipstick.

4. Repeat as needed, but don’t go above the max mark.

Typical top-up amounts for passenger cars:

-        Below min: Add 100–200 ml, then recheck

-        Still low: Add another 100 ml and recheck

-        Always confirm with your vehicle handbook

Adding too much oil can cause damage, so go slow. If you’re unsure, Sandicliffe staff can help you choose the right oil.

What should EV owners know about oil checks?

Electric vehicles (EVs) don’t need engine oil checks or changes. Instead, focus on battery and motor inspections. At Sandicliffe, we offer EV maintenance checks that cover all the essentials, so you can drive with confidence.

If you own both petrol/diesel and electric cars, remember to keep up with oil checks on your traditional vehicles. For EVs, regular servicing is still important—just with a different focus.
