Regular oil changes help to prevent these problems and prolong the life of the engine.

 

How Often Should I Change My Oil?

The recommended frequency for oil changes can vary depending on a number of factors, such as the make and model of the vehicle, the type of oil being used, and the driving conditions.

Typically, most car manufacturers recommend changing the oil every 3,000 to 5,000 miles or every 3 to 6 months (whichever comes first) for conventional oil. But for synthetic oil, it is recommended every 7,500 to 10,000 miles or every 6 to 12 months (whichever comes first).

It’s also important to check your vehicle’s owner manual for the specific recommendations for your make and model, as they may have specific recommendations. Additionally, if you drive in extreme conditions, such as hot weather or on dirt roads, or if you frequently tow heavy loads, you may need to change your oil more often.

It’s also important to keep an eye on the oil life indicator, which is found in most modern vehicles, it will tell you when it’s time for an oil change based on the mileage and usage.

 

How Do I Know When It’s Time To Change My Car’s Oil?

There are a few ways to know when it’s time to change your car’s oil:

  1. Check the owner’s manual: Most vehicle manufacturers provide recommended intervals for oil changes in the owner’s manual. Be sure to check this first.
  2. Check the oil life indicator: Many newer vehicles have an oil life indicator that displays the remaining life of the oil based on the vehicle’s usage and mileage. This indicator will typically light up or display a message when it’s time for an oil change.
  3. Check the oil level and appearance: You can check the oil level and appearance on the dipstick. If the oil is dirty, appears black and has a strong burnt smell, it’s time for an oil change. Also, if the oil level is too low, it’s time to add oil or schedule an oil change.
  4. Follow the 3,000-mile rule: As a general rule of thumb, it’s a good idea to change your oil every 3,000 miles or every 3 months, whichever comes first.

It’s important to keep in mind that these are general guidelines, and the specific needs of your vehicle may vary. Always consult your vehicle’s owner manual for the manufacturer’s recommendations.

Does The Fuel Type Matter?

by | posted in: Ask The Expert | 0

The main difference between gasoline for cars is the octane rating. Octane rating is a measure of a fuel’s ability to resist “knocking” or “pinging” during combustion, caused by the air/fuel mixture detonating prematurely in the engine. The higher the octane number, the greater the fuel’s resistance to knocking or pinging.

  1. Regular gasoline: This type of gasoline has an octane rating of 87, and is commonly known as “87 octane” or “unleaded gasoline”. It is the most widely available and the least expensive type of gasoline. It is suitable for most cars, but not recommended for high-performance engines.
  2. Mid-grade gasoline: This type of gasoline has an octane rating of 89, and is commonly known as “89 octane” or “plus gasoline”. It is more expensive than regular gasoline, but less expensive than premium gasoline. It is suitable for cars that require a higher octane gasoline, but not necessary for most cars.
  3. Premium gasoline: This type of gasoline has an octane rating of 91, 92 or 93, and is commonly known as “91 octane”, “92 octane” or “93 octane” or “super gasoline”. It is the most expensive type of gasoline and is typically used in high-performance and luxury vehicles.
  4. Diesel: Diesel fuel is a type of fuel that is used in diesel engines. It is different from gasoline in that it is denser, has a higher energy content and is less flammable. It is used in cars, trucks, buses, and other heavy-duty vehicles.

It is important to note that using a higher octane fuel than is recommended for your vehicle will not provide any benefit, and may actually decrease performance and increase fuel consumption. Always consult the owner’s manual or consult with Trinity AutoWorx to determine the appropriate fuel for your vehicle.
