When choosing the right oil for your vehicle, it’s essential to consider its specific needs.
Here’s how AMSOIL High Mileage and Signature Series stack up:

For vehicles that have seen many miles, the benefits of AMSOIL High Mileage are unmatched. It addresses the common concerns of older engines, making it an invaluable tool in my car maintenance kit.
Based on my experience, AMSOIL High Mileage is the unsung hero for older cars. It addresses the common issues of aging engines with a formula that revitalizes and protects, making it my top pick for vehicles with a lot of miles on them.

High mileage excellently prevents sludge and deposit buildup in older engines. Signature series also keeps engines clean but is more optimized for newer models.
High mileage is specially formulated to protect and extend the life of worn engine components. Signature Series offers superior wear protection but is geared towards newer engines.
High mileage significantly cuts down oil burning and consumption in older engines. The signature series is efficient but may not address older engine oil consumption as effectively.
High mileage contains seal conditioners that reduce leaks in aging engine seals. Signature series are less focused on this aspect for older engines.
High mileage is specifically designed to prolong the life of high-mileage engines. Signature series enhances engine life but is more effective in newer engines.
