Historically changing the motor oil in your vehicle has been a messy experience for the amateur mechanic. Typical problems have involved copious numbers of spillages onto driveways and pavements. Spillages like this are usually caused by the amateur being completely oblivious to how much oil 5 L actually is. Once you realize that it's not going to fit into your empty jumbo size ice cream carton then you have a real panic on your hands. Even an oil drain pan has been known to overflow.

Next comes soiled clothes and hard to clean hands, leaking oil plugs which never go on as long as they came off and various other almost comic incidents which seem funny when you look back on them but not at that time.
Many of these difficulties can now be avoided by using an oil extractor. These clever devices use a long flexible tube inserted right down the dipstick hole until they get to the oil sump. Once in place a few pumps on a handle and a vacuum is created causing the oil to be sucked up the pipe and into the unit self-contained storage area. No spillages guaranteed. The price of the engine oil extractor varies depending on the capacity of the storage and the amount of oomph in the pump, so if you think this could be a way forward for you make sure you find out how much volume of oil there could be in your oil pan.

One of the downsides of an oil extractor is that it can take are a bit longer for the pan to empty out. Sometimes as long as 30 minutes. When you change of motor oil you should also change your oil filter and this device can't help you with that. Overall they are a very good idea if you want to avoid some of the tricky situations described at the beginning of this article.

Finding an engine oil leak is a tricky business. You might think it would be obvious if your car was leaking oil but we are not talking about a filthy black stain forming beneath where you park. Although messy this type of leak is very easy to spot. No there is a different kind of leak, one that is nowhere near as easy to spot and often much more expensive to fix.

Inside the engine oil is used to lubricate moving parts. One of these parts is the pistons moving up and down in the cylinder head. The piston is pumped up and down using forces generated in the combustion chamber. The head gasket forms a seal between the cylinder and they engine block where the combustion chamber is. The seal between these two has to be tight to stop energy from escaping the combustion chamber (without being harnessed through the piston) and to prevent oil and coolant from entering the combustion chamber. If they gasket becomes damaged, either worn down or brittle then the seal is broken and you have an oil leak except this time it’s on the inside of the engine and can be much less obvious. One of the symptoms of this is his if the car’s exhaust has a blu-ish tint to the smoke coming out of it.

The other way to tell us if you're oil pressure gauge is showing a low-level and you're frequently topping it up.  Another way to tell is if the engine feels less powerful than usual but it is unlikely you would feel any difference under normal driving circumstances.

After getting a problem like this fixed you will need new oil. Always opt for an American petroleum Institute approved oil and do not be tempted to recoup some of the repair costs by choosing a cheap oil change.
