As a car owner with a high mileage vehicle, I have come to learn the importance of using full synthetic high mileage oil. In fact, it has become necessary for me to use this type of oil in order to maintain the health and performance of my vehicle.

One of the main reasons why full synthetic high mileage oil is necessary is because it provides better lubrication for the engine. As a car ages and accumulates more miles, its engine parts start to wear down. This can lead to increased friction and heat, which can cause damage to the engine. However, full synthetic high mileage oil is specially formulated with additives that provide enhanced lubrication and protection for older engines.

Moreover, this type of oil also helps to prevent leaks and reduce oil consumption. With age, the seals in an engine can become brittle and start to leak. Full synthetic high mileage oil contains seal conditioners that help to keep the seals pliable and prevent leaks from occurring. It also has a lower volatility rate, meaning it evaporates less which results in less frequent top-ups.

In addition, full synthetic high mileage oil helps to clean and protect the engine from harmful deposits. Over time, dirt and sludge can build up in an engine, causing blockages and reducing its efficiency. Full synthetic oils have

As a car enthusiast, I understand the importance of using high-quality oil for my vehicle’s engine. With increasing mileage, it is crucial to switch to a full synthetic high mileage oil to ensure the best performance and longevity of the engine. In this buying guide, I will share my personal experience and knowledge about full synthetic high mileage oil to help you make an informed decision.

What is Full Synthetic High Mileage Oil?

Before delving into the buying guide, let’s understand what full synthetic high mileage oil is. It is a specially formulated motor oil that is designed for vehicles with over 75,000 miles on their odometer. This type of oil contains additives that help reduce engine wear and extend its life.

1. Viscosity: The first thing you need to consider when buying any motor oil is its viscosity rating. For high mileage engines, look for an oil with a higher viscosity, such as 5W-30 or 10W-30.

2. Additives: Check for additives like seal conditioners, detergents, dispersants, and anti-wear agents in the product label. These additives provide extra protection for your engine.

3. Brand: Always opt for trusted brands when it comes to buying motor oil. They have a reputation for producing high-quality products that undergo rigorous testing before hitting the market.

4. Vehicle Compatibility: Make sure to check the manufacturer’s recommendations before purchasing an oil for your vehicle. Some oils may not be suitable for certain types of engines or vehicles.

Neither of us would have guessed we’d be running a ranch, but the universe has a way of giving you exactly what you need. Ranch life is demanding, but it’s our creative playground.

As yogis and meditators, we strive to emit balanced and loving energy. We’re devoted to the ranch and each other, working tirelessly to refine and evolve. Our heart and soul go into cultivating space for ease and joy.

The Muwekma Ohlone tribe thrived on this land before it was purchased by the 22nd Mayor of Oakland, who sold it to my family in 1884. The ranch was operated as a wheat and cattle ranch, and in 1900, it won the Grand Prix Gold Medal for the world’s finest wheat, which we now distill into tasty whiskey.

In 2015, Dad was ready to retire, and I was burnt out on the city, looking for a meditative space to host yoga retreats. So, I took the leap and met Albe two months later. How serendipitous! Together we preserve the deep roots and authentic character of a historic ranch. Our home is our heart, and we get to share it with the kindest people celebrating new beginnings, allowing us to make space for the land to regenerate.
