Think you can get away with just changing just your engine oil every 3000 miles? Think again!

Most Cars have many other oil and fluids that need to be service too! Believe it or not, you car actually uses seven or more different types of fluids and oils:... Motor Oil, Gear Oil, Coolant, Power Steering Fluid, Brake Fluid, Transmission Fluid, All Wheel Drive Oil, Transfer Case Fluid, and even Windshield Washer Fluid.

Because today's vehicles required very specific fluids and oils for each different type of model, you can no longer use the mindset of one fluids fits all. (This mistake will cost you $$). It's important to service these other systems regularly by changing these fluids & oils according to your car's maintenance schedule.

What's best Conventional Oil or Synthetic Oil?

Over the years, I've been asked many times, What’s best Conventional oil or Synthetic oil? Most wonder what the benefits are of using synthetic vs. conventional oil.

We all know the most common maintenance service that your car needs is changing your engine oil. Your engine oil not only lubricates the moving parts inside your engine but also cools and cleans it. When you change your car's engine oil you have a lot of choices, including the use of synthetic oil or conventional oil.

While most older vehicles initially used conventional motor oil to lubricate and protect critical engine parts, Conventional oils often break down fast and end up leaving deposits on engine components called "sludge". However, there are some conventional oils available that have the ability to remove some of these deposits. Over the years there has now become a wide range of conventional and synthetic motor oils to choose from. So, what is best? How do you know what motor oil to use?

The age of your vehicle and what it's used for plays a big part in this decision. Older vehicles and routine driving situations, such as commutes, errands, or vacation driving at normal speeds, may just require a conventional oil, while most newer vehicles and more aggressive driving, such as performance, longer driving time, hauling loads or towing, requires a synthetic oil.

So what’s best?

With today’s vehicles and even older vehicles synthetics motor oil is becoming the prefer oil to use. The best synthetic oils offer protection against many things such as: wear on dry startup, reduce heat build-up, enhance engine durability, help clean engines of deposits, helps to improve fuel mileage and longer service interval. All of this helps decreases wear over the long term, and promotes longer motor life.Although synthetic oil is better, conventional oil will protect your vehicle's engine just fine if keep it change. The most important thing you can do to keep your car running smoothly is to follow your vehicle manufacturer's recommended service intervals and change that oil regularly “NEVER PUSH IT PAST THE RECOMMEND SERVICE TIME”. Although it cost a little more money, the saving, is in the long term and the biggest difference is overall synthetic oil is better for your engine when compared to conventional oil. I recommend that you ask your mechanic for their recommendation when deciding on a brand type.
