Frequently Asked Questions

  • The frequency with which you should change your oil depends on several factors such as the make and model of your vehicle, driving conditions, and the type of oil you use.

    In general, it is recommended to change your oil every 5,000 to 7,500 miles or every six months, whichever comes first. However, if you frequently drive in severe conditions such as extreme temperatures, dusty roads, or heavy traffic, you may need to change your oil more frequently.

  • There are two main types of motor oil: conventional and synthetic. Conventional oil is made from crude oil and is less expensive than synthetic oil. Synthetic oil, on the other hand, is chemically engineered to provide better performance and protection for your engine.

    If your car is relatively new or has a high-performance engine, synthetic oil may be the best option. Synthetic oil can provide better fuel economy, improve engine performance, and protect your engine in extreme temperatures. However, if your car has an older engine or is not high-performance, conventional oil may be a suitable and less expensive option.

    It's important to check your vehicle's owner's manual for the manufacturer's recommended oil viscosity and type. This information will help you choose the right oil for your car and ensure that your engine is properly protected. Additionally, it's a good idea to consult with a trusted mechanic like Mountain Top Auto Service to help you determine the best type of oil for your car based on your driving habits and other factors.

  • While it's possible to go longer than the recommended oil change interval, it's generally not recommended. The recommended oil change interval is designed to ensure that your engine is properly lubricated and protected, and going longer than the recommended interval can increase the risk of engine damage and decrease its lifespan.

    If you go too long without an oil change, the oil can break down and become less effective at lubricating and protecting your engine. This can lead to increased friction and wear on engine components, reduced engine performance, and even engine failure.

  • Yes, it's recommended that you change the oil filter every time you change your engine oil. The oil filter is an important component of your engine's lubrication system, and it helps to remove dirt, debris, and contaminants from the oil as it circulates through the engine.

    Over time, the oil filter can become clogged with debris and lose its effectiveness. If you don't change the oil filter regularly, it can become less effective at filtering out contaminants, which can lead to increased wear on engine components, reduced engine performance, and even engine damage.

  • There are a few signs that you may need an oil change in your car. First, if a dashboard warning light comes on, this could indicate that it's time for an oil change. Second, if your engine sounds louder than usual, it could mean that your oil is dirty or low. Third, if your oil is dark and dirty when you check it with the dipstick, it may be time for a change. Fourth, if your oil level is low, it could indicate that it's time for a change or that your engine is leaking or burning oil. Fifth, if you've noticed a decrease in fuel economy, it could be a sign that your oil needs to be changed. Finally, if you can smell oil inside your car, this could be a sign that your engine is leaking or burning oil and needs attention. If you're not sure if it's time for an oil change or if you've noticed any of these signs, it's a good idea to have a trusted mechanic take a look.

  • Changing your own oil is possible, but it requires some mechanical know-how and the right tools. If you have experience with car maintenance and repair, changing your own oil can save you money and be a satisfying DIY project. However, if you're not familiar with car maintenance or don't have the necessary tools, it's probably best to leave it to a professional at Mountain Top Auto Service.

    Ultimately, the decision of whether to change your own oil or go to a professional depends on your level of experience, the tools you have available, and your personal preference. If you're not sure which option is best for you, it's a good idea to consult with a trusted mechanic or do some research to weigh the costs and benefits.
