Frequently Asked Questions
Why Do I Need AMSOIL High-Mileage Engine Oil?
It provides an added boost of detergents to clean up sludge and deposits left behind from prior use with a lower-quality oil. A robust viscosity provides additional wear protection even after some wear has occurred. Added seal conditioners extend the life of seals from drying, cracking and leaking.
AMSOIL 100% Synthetic High-Mileage Engine Oil is designed for the unique demands of engines with over 75,000 miles (120,700 km).
When Should I Use AMSOIL High-Mileage Engine Oil?
At or around the time your vehicle has 75,000 miles (120,700 km) on it.
Do I Need to Use AMSOIL High-Mileage Engine Oil if I’ve been using AMSOIL Engine Oil Already?
No. If you’ve consistently used AMSOIL engine oil, your engine has been protected. That being said, if you have been using OE and would like to upgrade overall engine protection as it ages, AMSOIL High-Mileage Engine Oil is an excellent choice.
I Thought AMSOIL Engine Oil Products Were Good for All Mileage?
Correct, all AMSOIL engine oil will perform and protect well regardless of miles on the vehicle. However, for those looking for targeted benefits at an affordable price, AMSOIL High-Mileage Engine Oil is the best choice for high-mileage applications. For those seeking ultimate performance and protection regardless of miles, we still recommend Signature Series Engine Oil.
Why Do I Need Hybrid Engine Oil?
Hybrid engines operate under a different set of conditions that often result in additional fuel and water contamination — and that leads to corrosion. Due to their frequent stops and starts, their engines operate at lower temperatures. AMSOIL Hybrid Engine Oil is uniquely formulated to address these specific challenges.
When Should I Use Hybrid Engine Oil?
AMSOIL Hybrid engine oil is an excellent choice for any Hybrid Electric (HEV) or Plug-in Hybrid Electric Vehicle (PHEV) regardless of miles or age of vehicle.
What If I’ve Been Using AMSOIL Already In My Hybrid Vehicle?
If you have been using AMSOIL products, your engine has received excellent protection. All AMSOIL PCMO products of the appropriate viscosity are compatible with hybrid technologies.
However, AMSOIL Hybrid Engine Oil has been engineered to focus on the unique challenges presented by hybrid vehicles and do it at an affordable price. If you have been using OE and are looking for an upgrade in hybrid engine protection, AMSOIL Hybrid Engine Oil is an excellent choice.
