Heat Puts Stress On Engine Oils

Sturgis Motorcycle Rally begins this coming weekend.

When you think about it, we demand a lot from our motor oil. For example, we all want better fuel economy, so we’re using lighter oils. However, we also want engines to produce more power per cubic inch. To add power, we’re putting in turbochargers which raise the engine temperatures and put higher stress on our oil.

That’s not the only stress. We value cleaner air, so new devices that reduce exhaust emissions place more contamination in the oil and increase engine temperatures. We’ve also cut aerodynamic drag, a plus for vehicle owners, but brutal on oil. By minimizing the air flow over the engine and drivetrain, temperatures also rise.

In fact, the average under-the-hood temperature had increased from 175 degrees Fahrenheit in 1975 to 225 degrees by 2000. Our vehicles are increasingly complex and powerful machines. To keep them running smoothly, we’re demanding that our lubricants do more and last longer.

That is why synthetic motor oils and drivetrain fluids have been increasing in market receptivity over the past two decades. For more information about AMSOIL synthetic motor oils, visit the AMSOIL website at www.amsoil.com.

With the Sturgis motorcycle rally just around the corner (AMSOIL staff will be on-site setting up by the end of this week) it seems a good time to share our new V-Twin Torture Test video.


You can see with your own eyes how heat puts stress on motor oils, especially in hard-working V-Twin engines. And how AMSOIL does its part to protect those engines. It's what we're about.
