Complete Coverage

AMSOIL European Motor Oil meets and often exceeds strict European manufacturer specifications. Its shear-stable synthetic base oils and high-quality anti-wear additives provide outstanding protection in high-temperature conditions and deliver dependable performance throughout the long drain intervals recommended by European manufacturers.

Emissions System Protection

AMSOIL European Motor Oil features precisely balanced formulations that consider the needs of modern exhaust treatment devices. Protecting sensitive emissions systems depends on using the optimal blend of SAPS (sulfated ash, phosphorus and sulfur). AMSOIL European Motor Oil is carefully crafted in eight varieties to ensure proper emissions system function.

Superior Engine Cleanliness

The excellent oxidation stability, heat resistance and detergency properties of AMSOIL European Motor Oil help keep engines clean. It is specifically designed to prevent sludge and varnish deposits, reduce oil consumption, extend engine life and provide maximum performance.

Excellent For Turbochargers

AMSOIL European Motor Oil has a robust composition that shields engines from the high temperatures produced by turbochargers. Its thermally stable oil formulation resists deposit formation and cools turbochargers. Its low pour point protects turbochargers against oil starvation in subzero temperatures and ensures a rapid return to appropriate oil pressure at startup.

SERVICE LIFE

Recommended for the extended drain intervals established by the vehicle manufacturer. Change oil filter at time of oil change.

COMPATIBILITY

AMSOIL 100% Synthetic European Motor Oil is compatible with other synthetic and conventional motor oils. Mixing AMSOIL motor oil with other oils, however, will shorten the oil’s life expectancy and reduce its performance benefits. AMSOIL does not support extended drain intervals where oils have been mixed. Aftermarket oil additives are not recommended for use with AMSOIL synthetic motor oils.

20 Years

5.0 / 5

For 20 years I am using the Amsoil and will mot use anything else. I owned many (more than 20) different cars during these years and always used Amsoil. My mechanic wouldn’t believe I was really planning to change the oil every 10 or 25 k miles, but after changing it couple of times and seeing the condition of the used oil and my engine now he is not surprised anymore .

Best oil

5.0 / 5

I only use Amsoil in all my cars. Even got a few others on board. The best hands down. I feel it’s protecting my engine parts and lubricating what it needs to.

Correct application

5.0 / 5

Bought the oil change kit that included 5qts of oil and the oil filter for my 2022 VW Taos. Maybe Amsoil should go one step further and include a crush washer that is required for the drain bolt at every oil change to ensure no drips.

Best oil for Jeep Gladiator EcoDiesel

5.0 / 5

This is the oil I'm using in my 23 Jeep Gladiator ecodiesel. I have almost 50k on the engine and recently had an analysis done after putting 5,900 miles on the oil. It came back saying: Metals are low next to universal averages, and those averages show typical wear for this type of engine after about 5,900 miles on the oil. These numbers show all is well with internal parts so feel free to add another 2K-3K miles to this oil.

Great oils

5.0 / 5

I have been trusting AMSOIL oils for years. I just had the Audi 3.0T engine internals inspected while doing some service, and the mechanic was surprised how clean it was at 130k miles.

Best oil on the market

5.0 / 5

I have used AMSOIL for years on several different vehicles and have NEVER had any engine or transmission failure’s . I’ve finally switched all of my stock 22 RAM 1500 Ecodiesel fluids to full AMSOIL and my truck runs cooler and shifts smoother. Additionally, AMSOIL tech support can answer all of your stupid questions from torque specs to fill capacity.
