Why is oil pressure and tyre pressure critical to my car’s well-being?

Two checks for your car

It is important to carry out regular maintenance checks on your automobile for your own safety and for the health of the vehicle. There are many different checks that you can perform but two are particularly important as they our essential for the safe and economical creation of power to drive the car and the application of that power on to the road surface.

Check your car tyres

The first is to make sure that your car tyres have enough air inside them. Running under inflated tyres can be a very risky business for several reasons. The first is that the handling of the car is dependent upon Tyre pressure, flat tyres i.e. not totally flat but under inflated, reduced responsiveness of handling. The effectiveness of the brakes is also reduced when the tower is not pumped up to its correct pounds per square inch. These are two safety issue but there are also good economic reasons. It takes more energy and therefore more gasoline to move an entire which is not fully inflated. And because more of the tyre is in contact with the road surface you will get more wear, meaning you have to replace the tire sooner. When you want to buy car tyres it’s a good idea to always use a reputable service station. Unless you are a real authority don’t be tempted to buy a cheap tyre from a bloke in the pub. It is very difficult to tell the condition of attire just by looking at it unless you have a very experienced eye.

Check engine oil levels

The second thing you need to check is the level of motor oil. If your car runs low on oil several bad things start to happen. Because oil helps with cooling the engine can begin to overheat, even if the cooling system is working fine. Because cool and cannot reach the inner core of the engine it relies on motor oil, which covers all the internal surfaces, to absorb heat and carry it away as it leaves the engine, before being called in the oil pan. Overheating of the inner engine is normally caused by drop in the oil pressure (oil pressure falls as the volume of motor oil falls, the oil pressure gauge will show this on the dashboard if you have one). Low pressure means the oil is not circulating quickly enough to extract the heat. If the level of oil is depleted it is difficult for it to lubricate moving part successfully. Without sufficient lubrication the engine becomes less efficient as friction has increased and even worse, can damage itself as these components such as pistons in the cylinder head and the bearings in the crankshaft begin to wear each other down. In some extreme cases it has even been known for components to become welded together as they get so hot hand do not have lubrication to cool and protect them. Although low pressure is usually caused by a lack of a faulty oil transfer pump can also cause problems.

Do you check your car every week?

See results


As you can see these are two very important checks to perform on a regular basis. How regular depends on the age of your car and its condition. The new cars you will have to do these things so often but it’s still a wise precaution to check them every three or four weeks. If you have an old car that needs a lot of maintenance will probably be checking every week or even more in some cases by keeping an eye on them you can prevent any problems before they occur.
