David's engine builder recommended the AMSOIL 20W-50 but we felt the 10W-40 AMO (High Zinc) would serve him better. Sure enough he called back saying in 20 years that engine never ran so smooth. He was more than impressed actually and voiced that for now on he will be steering everyone to us for their oil needs. The Z-ROD is great but the AMO is the only 10W-40 which is in the middle of the Z-Rod range (20W-50 and 10W-30) so it's perfect. If the motor is built to factory specs in that era then use the OEM recommendations. Increase to 20W-50 if using other than gasoline fuels or there is significant wear which in this case there wasn't.
Bryan Ebersohl, the maintenance supervisor and batch plant foreman at St. Louis Prestress, was looking for a way to save money when he decided to try AMSOIL Synthetic Multi-Purpose Grease NLGI #2 on the expensive bearings of the huge machines. “These machines have vibrating augers that run about 16,500 rpms,” Ebersohl said. “I have tried lots of different grease trying to get a little longer life out of these bearings because they are very expensive. I used to change bearings about every 100 hours, because the grease would not hold up.” “Since I started using the AMSOIL grease I checked the bearings at 100 hours, 200 hours, 300 hours, all the way to 600 hours,” Ebersohl said. “This grease has saved our company thousands of dollars on bearings. The bearings cost between $75 and $180 each and we have 192 in use at one time.
The AMSOIL Interceptor 2-stroke injector oil is the only choice for any sled because it completely put an end to the choking smoke our group was so used to. No more oil residue on windshields and hacking up your lungs the next day. Oh, and it cuts down on maintenance on the sled too!

Many people think America’s best days for innovation and manufacturing are behind us. That companies are increasing margins instead of increasing quality. Al Amatuzio, the founder of AMSOIL INC., thinks otherwise. For over 40 years, AMSOIL has been formulating, blending, packaging, and serving as a leader in the synthetic lubrication industry. American innovation is indeed alive and well. Watch this video to learn more about Al Amatuzio’ s persistence in building an American company based on American values.
AMSOIL President and CEO Al Amatuzio founded his company on the same principles that defined his career as a jet fighter squadron commander – excellence, integrity and strong leadership. In 1972, the breakthrough came. AMSOIL 10W-40 Synthetic Motor Oil, the result of years of research and inspired by aerospace technology, became the first synthetic motor oil in the world to meet American Petroleum Institute service requirements. It outperformed conventional oils on all counts, signaling a new age in lubrication science. Today, virtually every other motor oil manufacturer has recognized the superiority of synthetic lubricants and followed the AMSOIL lead with introductions of synthetic motor oils of their own. Accept no substitutes – AMSOIL is The First in Synthetics®.
Hall of Fame
In 1994 Al Amatuzio was honored as the pioneer of synthetic lubrication with his induction into the Lubricants World Hall of Fame.
Although you might know that synthetic oils outperform conventional oils, you might not understand why. The differences begin at the molecular level.
AMSOIL invests heavily in product research and validation to ensure we remain at the industry’s forefront. Our on-site chemical and mechanical test facilities contain the sophisticated instruments needed to develop cutting-edge synthetic technology. AMSOIL synthetic lubricants are validated in long-range studies with taxicabs, delivery fleets, police and emergency vehicles, over-the-road trucks, wind turbines and industrial machinery.
Further testing occurs at race tracks around the world. AMSOIL lubricants have helped racing teams operating off-road trucks, stock cars, high-powered boats, dirt bikes and snowmobiles capture countless checkered flags and championships. We believe that Racing is Research™, and we use the data our racing efforts generate to tailor AMSOIL formulations for even greater levels of performance and protection.
Holding ourselves to higher quality standards is our industry trademark. We select raw materials based on quality and performance, not price. Each chemical is tested to ensure it meets our quality standards before it is accepted into our manufacturing facility. Our manufacturing process uses a strictly controlled computerized process to maintain top-quality finished products.
Samples of the finished product are subjected to a series of industry-standard tests prior to packaging. Every product AMSOIL manufactures is tested every time it is blended to ensure maximum quality and consistency, ensuring AMSOIL customers receive the same high performance every time they purchase AMSOIL synthetic lubricants
