Why AMSOIL — The First in Synthetics® Since 1972
AMSOIL pioneered synthetic lubrication in 1972 and remains the industry leader in performance, protection, and innovation. Discover the history, the science, and the guarantee that have earned AMSOIL the trust of enthusiasts, mechanics, and fleet operators across America.
Ahead of Our Time
AMSOIL founder Al Amatuzio — a jet fighter squadron commander — built his company on the same principles that defined his military career: excellence, integrity, and strong leadership. In 1972, the breakthrough came. AMSOIL 10W-40 Synthetic Motor Oil, inspired by aerospace lubrication technology, became the first synthetic motor oil in the world to meet American Petroleum Institute (API) service requirements.
It outperformed conventional oils on every count, signaling a new age in lubrication science. Today, virtually every major oil company offers synthetic oil — but AMSOIL created the category and continues to set the standard. In 1994, Al Amatuzio was inducted into the Lubricants World Hall of Fame as the pioneer of synthetic lubrication. Accept no substitutes — AMSOIL is The First in Synthetics®.

Why AMSOIL Outperforms
Superior Engine Protection
Independent testing demonstrates that AMSOIL Signature Series Synthetic Motor Oil provides significantly more protection against horsepower loss and wear than required by leading industry specifications. AMSOIL's proprietary additive packages fight sludge, deposits, and corrosion — keeping engines cleaner, cooler, and running like new for longer.
Extended Drain Intervals
AMSOIL synthetic oils are engineered for extended drain intervals, reducing maintenance frequency and total cost of ownership. Their robust formulations resist thermal and oxidative breakdown far longer than conventional and competing synthetic oils — change your oil less often with complete confidence in continued protection.
Extreme Temperature Performance
AMSOIL synthetic lubricants maintain protective viscosity across extreme temperature ranges — flowing readily in sub-zero conditions for instant cold-start protection while resisting thermal breakdown at sustained high operating temperatures. From Florida heat to northern winters, AMSOIL delivers dependable performance.
Complete Synthetic Product Line
AMSOIL manufactures premium synthetic lubricants for virtually every application: motor oil, diesel oil, transmission fluid, gear lube, grease, hydraulic fluid, fuel additives, coolant, filtration, and more. Whether you drive a passenger car, operate a commercial fleet, ride a motorcycle, or run heavy equipment — AMSOIL has the right product for your needs.
Runs on Freedom®
The AMSOIL Guarantee — Your Warranty Stays Intact
In America, the federal Magnuson-Moss Warranty Act protects your freedom to choose the brand of parts and lubricants you think is best — without fear of voiding your factory warranty. AMSOIL backs that freedom with one of the strongest guarantees in the industry.
Illegal to Tie Warranty
It is illegal for manufacturers to tie warranty coverage to whichever brand of parts or lubricants you use. If they require a specific brand, they must provide it free of charge.
Freedom to Choose
You have the freedom to choose how you protect your vehicles and equipment — including products formulated for extended drain intervals like AMSOIL.
No Mileage Cap
The AMSOIL Limited Warranty has no restrictions based on total vehicle miles. AMSOIL stands behind its products for as long as you use them.
Warranty Secure: AMSOIL products are high-performance replacements for vehicle and equipment manufacturer-branded products, keeping your factory warranty intact. Manufacturers cannot deny warranty coverage without proving the aftermarket lubricant caused a failure.

Research & Real-World Validation
AMSOIL invests heavily in product research and validation. On-site chemical and mechanical test facilities house sophisticated instruments needed to develop cutting-edge synthetic technology. AMSOIL synthetic lubricants are validated in long-range field trials with taxicab fleets, delivery trucks, police and emergency vehicles, over-the-road semis, wind turbines, and industrial machinery.
Further testing happens at race tracks worldwide. AMSOIL's mantra — Racing is Research™ — drives data from off-road trucks, stock cars, dirt bikes, snowmobiles, and high-powered boats back into formulations for street and fleet use.
Quality First
Holding to higher quality standards is an AMSOIL trademark. Raw materials are selected based on quality and performance — not price. Each chemical is tested before it enters the manufacturing facility. Every batch is tested again before packaging to ensure consistency.
- High-quality raw materials
- ISO 9001 — Quality Management
- ISO 14001 — Environmental Management
- Every batch tested before packaging
