For something so small, engine oil does a huge job. From keeping your engine parts lubricated to helping your car run cooler and cleaner, regular oil changes are a non-negotiable part of vehicle maintenance. Yet, many drivers still treat them as optional or delay them far too long.
If you’re unsure how often to book a car oil change, what type of oil your car needs, or why it really matters, this guide covers the essentials. We’ve also included pricing information and a visual tip to help you spot the warning signs of neglected oil.
What Does Engine Oil Do?
Think of oil as your engine’s lifeblood. It lubricates moving parts, reduces friction, prevents overheating, and even helps clean out micro-debris and contaminants. Over time, though, oil breaks down, especially when exposed to extreme temperatures or dirty conditions. Once that happens, its ability to protect your engine plummets.
That’s why most vehicle manufacturers recommend a regular oil change based on mileage, driving habits, or time passed since your last car service. Ignoring it for too long can cause long-term (and expensive) damage to your engine.
Understanding Oil Grades: What Do 5W-30 and 0W-20 Mean?
When you see engine oil grades like 5W-30 or 0W-20, they’re not just random numbers. These refer to the oil’s viscosity, or thickness, at different temperatures. The “W” stands for “winter,” indicating how the oil flows when cold. The lower the number before the W, the better the oil performs in cold starts.
For example:
- 0W-20 is thinner and flows faster at lower temperatures—good for newer engines and colder UK winters.
- 5W-30 is a common all-rounder for many petrol and diesel engines, providing balance in both warm and cold conditions.
In the UK’s fairly mild climate, most vehicles can safely run on 5W-30 or 5W-40 unless your manufacturer specifies otherwise. However, if your car has start/stop technology or is a hybrid model, you might benefit from switching to a more advanced oil like 0W-20.

The Hidden Damage of Skipping Your Oil Change
Putting off your oil change might seem harmless, but over time, it can lead to serious damage. Here are three silent engine killers that result from neglecting this simple task:
- Oil Sludge Build-Up – Old oil turns into a thick, sticky sludge that clogs your engine, restricts flow, and starves parts of lubrication. Sludge can lead to overheating and even total engine failure.
- Accelerated Engine Wear – Without proper lubrication, internal components grind against each other, causing irreversible wear to pistons, bearings, and camshafts. This wear adds up quickly, especially in stop-start urban driving.
- Contaminant Buildup – Over time, oil becomes contaminated with carbon deposits, metal fragments, and dirt. If not changed regularly, these particles circulate through your engine and reduce its efficiency and lifespan.
How Much Does an Oil Change Cost? Standard vs. Synthetic Oils
Oil changes vary depending on the type of oil your vehicle requires. At most motor garages, including First Auto Centre in East Ham, you’ll typically find prices fall into one of three bands:
- Standard Mineral Oil Change: £50–£70 – Suitable for older vehicles or light, low-mileage use. Less durable and requires more frequent changes.
- Synthetic Blend Oil Change: £70–£90 – A mixture of mineral and synthetic oils offering better performance and protection. Ideal for most mid-range vehicles.
- Full Synthetic Oil Change: £90–£120 – Provides the highest level of protection, especially for high-performance engines, turbocharged vehicles, or those doing long-distance or city stop-start driving.
At First Auto Centre, your oil change includes a new filter, proper disposal of old oil, and a check of other key fluids—because a quick fix should still be done properly.
How Often Should You Change Your Oil?
A general rule of thumb is:
- Every 5,000 to 7,500 miles for synthetic blend oils
- Every 7,500 to 10,000 miles for full synthetics
- Every 3,000 to 5,000 miles for standard oils
But it’s not just mileage that matters. If you only drive short distances or leave your car sitting unused, your oil can still degrade due to moisture and temperature changes. That’s why we recommend an annual oil change, even for low-mileage drivers.
