The smaller the weight loss due to high temperature evaporation, the better the oil retains its ability to lubricate and protect the engine.

AMSOIL Synthetic Motor Oils

are the right choice for contemporary performance vehicles. Take a look at the facts:


Unlike conventional motor oils that contain non-essential molecules that do virtually nothing to protect the engine - and contain elements that actually harm it - AMSOIL synthetic motor oils are pure and molecularly uniform. Every single molecule in AMSOIL synthetic motor oils is dedicated to engine lubrication and protection.


AMSOIL synthetic motor oils exceed the most demanding world-wide performance specifications, meeting warranty requirements for all domestic and imported passenger car and truck engines.


AMSOIL synthetic motor oils reduce friction more effectively than conventional petroleum motor oils do. Less friction means less engine wear, better fuel economy and improved power and performance.


AMSOIL synthetic motor oils inhibit the formation of sludge, varnish, acids and other harmful deposits. Engines stay cleaner, perform better and last longer.


AMSOIL synthetic motor oils do not "burn off" like conventional petroleum motor oils do. AMSOIL synthetic motor oils retain their viscosity, providing reduced oil consumption, improved fuel economy and better wear protection.


AMSOIL synthetic motor oils remain fluid in the cold temperatures that gel conventional petroleum oils. With AMSOIL synthetic motor oils, engines start easier and are assured immediate start-up protection.

In 20 years, engine speeds have increased 50 percent. Modern engines are smaller, leaner-burning, hotter-running, have higher compressions and use smaller radiators and oil sumps. Many use turbochargers and multivalve heads which boost rpms and temperatures even higher.

Over the same period, oil drain intervals have increased as much as 300 percent. Modern engines produce more power with better fuel economy and fewer emissions than ever before, and the oil protecting them is working harder than ever, too.

Dominator Synthetic Racing Oil

Perfect for engines exposed to high ambient temperatures and extraordinary performance demands, Dominator Synthetic Racing Oil is available in SAE 5W-20, 10W-30, and 15W-50, and is the choice of race engine builders across North America for its ability to protect and increase power. Dynamometer testing, performed by independent race engine builders, shows:

AMSOIL Synthetic Premium Protection Motor Oil

Formulated for use in gasoline engines, pre-2007 on-road diesel engines and all model year off-road diesel engines. Offers excellent wear protection. Ideal for applications where the extra protection of a high zinc formula is desired, including hot rods, motorhomes and motorcycles. Excellent for flat tappets, high performance, heavy duty and high mileage applications. Synthetic Premium Protection Motor Oil is available in SAE 10W-40 and 20W-50.

AMSOIL Signature Series Synthetic Motor Oil

Dramatically outperforms conventional petroleum motor oils. Reduces friction, heat and wear for maximum power, performance and fuel efficiency. Resists high-temperature burn-off, chemical breakdown and sludging - keeps engines cleaner. Outstanding low-temperature fluidity for fast, dependable winter starts and immediate start-up protection. Exceeds the most demanding world-wide performance standards and meets warranty requirements for all domestic and imported passenger car engines, both turbocharged and non-turbocharged. Up to 25,000-mile or 1-year drain intervals.

Z-ROD™ Synthetic Motor Oil for Classic and High Performance Vehicles Featuring a High-Zinc Formulation

AMSOIL Z-ROD™ Synthetic Motor Oil is specially engineered for classic and high-performance vehicles and features a high-zinc formulation to prevent wear on flat-tappet camshafts and other critical engine components, along with a proprietary blend of rust and corrosion inhibitors for added protection during long-term storage. Z-ROD Synthetic Motor Oil is designed to perform on the street and protect during storage.

Break-In Oil (SAE 30) -- Designed for High-Performance and Racing Engines

AMSOIL Break-In Oil is an SAE 30 viscosity grade oil formulated without friction modifiers to allow for quick and efficient piston ring seating in new and rebuilt high-performance and racing engines. It contains zinc and phosphorus anti-wear additives to protect cam lobes, lifters and rockers during the critical break-in period when wear rates are highest, while its increased film strength protects rod and main bearings from damage. AMSOIL Break-In Oil is designed to increase compression, horsepower and torqe for maximum engine performance.
