Motul recently launched Motul 8100 Power for the North American market.
Motul developed 8100 Power specifically for performance street vehicles that do not require a dedicated track motor oil such as Motul 300V, the company said.
The 100% synthetic, ester-based engine oil replaces and expands upon the Motul Sport line and is available in four viscosities for use in naturally aspirated and forced-induction gasoline and diesel engines.
“Engineered with modern performance engines in mind, 8100 Power provides the ideal balance between performance and protection,” said Motul USA Marketing Manager Nolan Browning. “With 8100 Power, we are taking what we’ve learned from our decades as a leader in motorsport lubrication technology and applying it to high-performance and tuned street cars. It’s the perfect addition to our line of motor oils for everything from general service to extreme track use.”
The new line of
link hidden, please login to view is specially formulated to ensure performance and reliability for turbocharged or naturally aspirated light-duty diesel or gasoline engines across a broad range of temperatures and engine RPMs, according to Motul. Motul 8100 Power is engineered to protect against the risk of low-speed pre-ignition in small-displacement turbocharged direct-injection engines. It delivers oil-film resistance at elevated temperatures for peak engine power, torque and anti-wear protection, thanks to a unique combination of ester base oils and friction modifiers, according to the company.
Motul 8100 Power also maintains compatibility with manufacturer warranties with vehicles requiring API SP-grade lubricants as well as full compatibility with bioethanol (E85 and E100), LPG (liquefied petroleum gas), CNG (compressed natural gas) and diesel fuels.
Motul 8100 Power is available in 0W-20, 5W-30, 5W-40 and 5W-50 viscosities in 1-liter and 5-liter containers. The high-performance lubricant already has been recommended and extensively tested for high-performance vehicles at manufacturer-recommended drain intervals.

The U.S. Department of Transportation’s National Highway Traffic Safety Administration (NHTSA) announced a notice of proposed rulemaking that would require automatic emergency braking (AEB) and pedestrian AEB systems on passenger cars and light trucks.
The proposed rule is expected to dramatically reduce crashes associated with pedestrians and rear-end crashes, according to the agency.
NHTSA projects that the proposed rule, if finalized, would save at least 360 lives a year and reduce injuries by at least 24,000 annually.
In addition, the AEB systems would result in significant reductions in property damage caused by rear-end crashes, according to NHTSA. Many crashes would be avoided altogether, while others would be less destructive.
“Today, we take an important step forward to save lives and make our roadways safer for all Americans,” U.S. Transportation Secretary Pete Buttigieg said on May 31. “Just as lifesaving innovations from previous generations like seatbelts and air bags have helped improve safety, requiring automatic emergency braking on cars and trucks would keep all of us safer on our roads.”
The

The NRSS adopts the safe-system approach and builds multiple layers of protection with safer roads, safer people, safer vehicles, safer speeds and better post-crash care, according to the agency. As part of the safe system approach, the proposed rule highlights safer vehicles and the DOT’s effort to expand vehicle systems and features that help to prevent crashes. An AEB system uses various sensor technologies and sub-systems that work together to detect when the vehicle is close to crashing, and then automatically applies the vehicle brakes if the driver has not done so, or applies more braking force to supplement the driver’s braking as necessary to avoid or mitigate the severity of the crash.
“We’ve seen the benefits of the AEB system in some passenger vehicles already even at lower speeds, and we want to expand the use of the technology to save even more lives,” NHTSA Chief Counsel Ann Carlson said. “That’s why our proposed rule would require all cars to be able to stop and avoid contact with a vehicle in front of them up to 62 miles per hour. And the proposal would require pedestrian AEB, including requiring that AEB recognize and avoid pedestrians at night,” “This proposed rule is a major safety advancement.”
If adopted as proposed, nearly all U.S. light vehicles (gross vehicle weight rating of 10,000 pounds or less) would be required to have AEB technology three years after the publication of a final rule.
This notice is a direct response to a provision in the
