Buyer Guide for High Mileage Oil

What is a High Mileage Oil?

High mileage oil is specially formulated for engines that have accumulated significant mileage.

They typically contain additives that help to seal leaks, reduce friction, and improve overall engine performance. If your car has over 75,000 miles, using high mileage oil can help extend the life of your engine.

Key Features to Consider

• Viscosity: Oil viscosity refers to its thickness. Choose the viscosity recommended in your owner’s manual. Common high mileage oils are 5W-30 or 10W-30.

How to Choose the Best High Mileage Oil

The best high mileage oil for you depends on your individual needs and driving habits. Consider these factors:

• Driving Conditions: If you frequently drive in extreme temperatures or challenging conditions (e.g., stop-and-go traffic), choose an oil with enhanced protection.
• Budget: High mileage oils come in various price ranges. Set a budget and look for a quality oil within your price point.

What kind of warranty does high mileage oil typically come with?

Most high mileage oil manufacturers offer a satisfaction guarantee, typically ranging from 30,000 to 60,000 miles, depending on the brand and product. This warranty usually covers defects in materials and workmanship, providing you with peace of mind and protection against faulty products.
