Worn Gaskets Or Sealers

Oil leaks are a significant possibility if your car has a damaged or a worn out crankshaft seal. If this happens, you’ll find that your engine will immediately start to lose oil whenever you’re driving. And, over time, you’ll find yourself having to constantly top off your oil in order to avoid damage to the engine.

If you find that your gaskets or seals are leaking oil, then bring your car to our shop and we will be able to help you check it out. The process is easy and inexpensive, so you can rest assured that you will be able to enjoy high-quality service without paying a fortune.

Low-Quality Oil

It is also possible for you to use the wrong type of oil in your engine. Or, in some cases, your oil could be too old and could have taken in a lot of dirt and debris. In both cases, the oil will start to burn up rather quickly.


Even more important is the fact that your oil could lose its ability to lubricate the components of your engine due to its low-quality condition. Over time, your engine itself will be forced to consume more oil. Thus, you waste oil and could even suffer some damage to your system.

If you notice your oil getting black or dark brown in color, then bring it to the shop and we can easily help you to change it as quickly as possible. While you can do this yourself, finding the right technicians will be more advisable. This is why we’re here to help.


Worn Piston Rings

Oil will be able to seep through worn-out or damaged piston rings and into the internal combustion chamber. As a result, the oil will burn and carbon deposits will build up on the cylinders and piston rings.

The worst part is that when your oil level drops, you will need to keep topping it off. It is only a good idea to replace your piston rings.

High Oil Pressure

When the pressure on your oil is excessive, it’s easy for it to flood through the entire engine in massive amounts. Essentially, this oil will most likely fall on the cylinders and get burnt.

High oil pressure could happen due to a wrong setting on the central computer of your car. Another cause could be you adding too much oil during an oil change.

A Worn engine

Your engine will perform optimally throughout the first five years of its lifespan. Because its parts are still young and robust, these are the years when the engine will use the least amount of oil. But, when enough miles have been put on your engine, the various seals and gaskets will start to wear out and start to leak in small amounts.

This implies that the engine will simply use oil more quickly. Also, older cars have tighter tolerances where parts link, which can allow oil to enter places where it wouldn’t be able to in more recent models.
