Oil is just as important as petrol, and without it we wouldn’t have a properly functioning petrol or diesel motor. There are many different kinds of email to choose from, and each will vary in terms of thickness.
Oil should always be kept at the correct level, and regular oil changes will ensure that you engine is running smoothly. Problems occur when oil is left too long without a change, or left to dip below the ‘min’ and the max’ mark on the dipstick.
If you want to keep your car running smoothly then oil should be checked on a regular basis, because it can be the root to numerous other issues and perhaps costly engine repairs.
