Engine Lubrication

If your car is not experiencing an adequate amount of lubrication then the valves, pistons and other parts of your engine are all at risk of overheating, which can cause a significant amount of damage. All of the moving parts of your engine move at a considerably high speed under your vehicle. Therefore it is critical you replace the oil regularly to keep them functioning in the best possible condition.


As we previously mentioned, ensuring your car oil is topped up or changed can cool down the components of your vehicle. Without sufficient oil, car parts can overheat very quickly. Ensuring all of these parts are lubricated will simultaneously keep the cooler. By doing so, you also prevent the parts from causing friction which can cause damage to parts that are relatively expensive to replace.

Regular maintenance and care on your vehicle can undoubtedly make your car last significantly longer.

The best ways to check your oil

If you are a new driver or someone who has been driving their own vehicle for a while now it is always essential you know how to check the oil on your vehicle. If you leave your engine oil for too long and allow it to go below the minimum level, your engine is much more at risk of overheating, when the vehicle overheats it can cause the engine to seize up which can be detrimental to the components. Unfortunately, these are not parts that are easily repaired, you will have to spend a considerable amount of money to have this fixed, and in most cases, you are better off buying a whole new vehicle in comparison to fixing it. In a similar way to having to little oil, if you have too much in your car, you can also be open to damage. So, it’s about getting the balance right.

checking dipstick

To check your oil, you will first want to open your car bonnet and locate the dipstick. This is normally easy to find and will have a bit at the top in which you can pull, make sure you give this stick a good wipe with some kitchen towel until all of the oil has been removed. You will then want to reinsert it back into the hole it came from, remove it again and check the level of your oil. It should always be within the maximum and minimum line. If your oil line is between these two markers, then you are fine to leave it, however, if it is below or two high you will need to rectify this.

You must also be aware that your car needs a sufficient amount of oil to pass its MOT in Milton Keynes, without it they cannot test your car’s emissions which will result in an instant fail.

When should I change my oil?

There are a few things you need to look out for when it comes to changing your oil.


When it comes to checking the colour of your oil, you ideally want it to be a transparent golden or light brown colour as this will indicate the oil is fresh. If your oil is much darker and not transparent, then you will need to make sure you change the oil.

Warning lights

Newer vehicles will indicate your oil is low or needs changing via their warning lights, the majority of newer model vehicles will have monitors or sensors placed within the car that will let you know when you should consider looking at your oil.

However, we would like to mention; older models do not have these functions, so please do not rely on your vehicle telling you when to change your oil.


One of the easiest ways to see if your car needs its oil changed is to check the consistency, remove a small amount off the dipstick and rub it between your thumb and forefinger. If the oil has more of a gritty consistency or course texture, suggest it need changing as it is most likely contaminated.
