Best Transmission Fluid for High Mileage Cars

Introduction

As your car ages, its transmission will require more care and maintenance. This includes changing the transmission fluid regularly. The right transmission fluid can help to extend the life of your transmission and prevent costly repairs.

What to Look for in a Transmission Fluid for High Mileage Cars

When choosing a transmission fluid for a high mileage car, there are a few things you should keep in mind:

• Viscosity: The viscosity of a transmission fluid is a measure of its thickness. A higher viscosity fluid will provide more protection for your transmission, but it can also make it harder to shift gears. For high mileage cars, a lower viscosity fluid is usually a better choice.
• Additives: Transmission fluids contain a variety of additives that help to protect your transmission from wear and tear. These additives can include detergents, anti-oxidants, and anti-wear agents. Look for a transmission fluid that contains a good balance of additives.
• Compatibility: Make sure that the transmission fluid you choose is compatible with your car’s transmission. You can check your car’s owner’s manual to find out which type of transmission fluid is recommended.
