Day in and day out, your Mercedes-Benz tires go around and around. You might think, “they work fine”. That is because it is difficult to notice that your front tires wear faster than the rear tires. Most people don’t notice it until it is too late. That is why it is always important to rotate the tires on your Mercedes-Benz. Tire rotations ensure treads wear evenly and tires last longer. How Often Should I Have Tire Rotations Done? Tire rotations should be done every 3,000-5,000 miles, or as specified by the manufacturer. Typically, you should have this service performed with every oil change. That way, you can save yourself a trip and not have to worry about keeping a record of the service. Why Can’t I Just Do It Myself? While it is possible to switch the positioning of your car tires on your own, it is highly not recommended. It requires extra time and labor when you don’t have the right experience, skills, or tools. T ... read more

When you think of a hybrid or electric vehicle, the first thing that comes to mind is probably the environment-friendly aspect. While this is undoubtedly true, there are other benefits to driving these types of cars. One of them is the use of regenerative braking systems. But how do regenerative braking work in hybrid and electric vehicles? This article will discuss how regenerative braking works and how it can benefit drivers of hybrid and electric cars. What is Regenerative Braking? Regenerative braking is a process in which the electric motor in hybrid and electric vehicles acts to convert kinetic energy into electrical energy. The vehicle battery stores this energy for later use. This braking system works in a two-way energy flow in which the motor converts energy into electricity to recharge the vehicle's battery instead of using the power to propel the car forward. Traditionally, in older cars, the energy produced when braking becomes heat. Over time wearing of the brake p ... read more

Most Porsche owners will do anything and everything to keep their vehicle in good shape (or at least they should!). One way to do this is by being aware of your engine health. The engine needs more than engine oil to keep its temperature stable and operations in line. One major component that supports the engine is the oxygen sensor(s). Read on to understand what an oxygen sensor is and how it works and the symptoms that indicate when they have gone bad.  What is an Oxygen Sensor? An oxygen sensor, or O2 sensor, is a sensory device that computes and assesses the oxygen levels in the Porsche’s exhaust system. It constantly sends information to the car's computer, which then tells other parts to make changes to the air-to-fuel ratio accordingly. When your car is able to achieve a balanced air and fuel mixture, your Porsche will run efficiently and smoothly. What Are the Signs of a Faulty Oxygen Sensor? There are several symptoms that indicate when the oxygen sensor has ... read more

I'm guessing you've been at the gas pump recently. The price of gasoline has been at an all-time high. This is why you're thinking of getting a vehicle with a hybrid engine. However, you don't know how a hybrid engine works. Hence this article. In this article, you'll learn everything you need to know about how hybrid engines work. What is A Hybrid Engine? A hybrid engine is a powertrain that uses both electricity and gasoline. A vehicle with a hybrid engine has an electric motor and a gasoline engine. How Do Hybrid Engines Work? There are different types of hybrid cars. And every kind of hybrid car has a different way how the engine works. In general, though, all hybrid engines work by using both the electric motor and the gasoline engine to power the vehicle. The electric motor is used for low-speed driving and starting from a stop. The gasoline engine is used for higher speeds. In parallel or mild hybrid cars, the engine comes with several advanced techn ... read more
