Buyer’s Guide for the Best Full Synthetic Oil
- So, why should you invest in best full synthetic oil as opposed to conventional oil or synthetic blends? Well, long story short, it’s just better for your car.
- Synthetic oil is produced in a lab and is engineered to perform better under a variety of engine conditions.
- Special additives can be included in the oil to tailor it to the needs of specific types of vehicles.
- When shopping for oil, you’ll notice the grade, such as 5W-30 or 10W-40.
- This is the viscosity grade, and it’s important. The first number represents the “winter” grade, and the second number represents the high-temperature grade.
- The lower the first number is, the thinner the oil is in cold weather.
- It needs to be thin, so the engine doesn’t have to work as hard to get started.
- Once everything is heated up, the oil thickens to better protect the running engine.
- You’ll need to consult your owner’s manual for the recommended viscosity grade for your particular vehicle.
- Synthetic oil has a better viscosity index, meaning that it doesn’t get too thick or too thin when the temperature in the engine changes. It will also last longer in your vehicle.
Important Reminder
- Less synthetic oil is lost to evaporation when compared to conventional oil.
- You can get up to 25,000 miles out of some best full synthetic oil, while a conventional oil will generally need to be changed at least every 5,000 miles.
- One thing you can look for when shopping for oil is the API label.
- This is a designation given by the Petroleum Quality Institute of America.
- They certify that engine oils meet certain quality and performance standards.
- This can give you a good idea of the quality of the oil you are looking at, and also whether or not it is appropriate for your vehicle based on the vehicle’s age.
- Other benefits of best full synthetic oil include better engine cleaning properties and anti-wear properties, due to the specific additives used.
- Your engine needs oil to prevent friction internally, and best full synthetic oil is durable and effective.
- All these factors will improve the overall fuel economy and the life of your vehicle, saving you money in the long run.
