What is synthetic motor oil? AMSOIL synthetic lubricants are chemically engineered to form pure lubricants. They contain no contaminants or molecules that don’t serve a designed purpose. Their versatility and pure, uniform molecular structures impart properties that provide better friction-reduction, optimum fuel efficiency, maximum film strength and extreme-temperature performance conventional lubricants just can’t touch.
Conventional lubricants, on the other hand, are refined from crude oil. Contaminating elements such as sulfur, nitrogen, oxygen and metal components such as nickel or vanadium are inherent to crude oil and cannot be completely removed through the refining process. The oil refining process separates the various types of molecules in the oil by weight, leaving molecules similar in weight but dissimilar in structure, reducing performance.
AMSOIL synthetic lubricants deliver wear protection, engine cleanliness and fuel efficiency conventional oils simply can’t match. They help your vehicles run better and last longer...
Synthetics don’t contain the impurities and molecular irregularities inherent to conventional oils. Synthetics’ pure, uniform molecular structures impart properties that provide wear protection, extreme temperature performance and fuel efficiency conventional lubricants just can’t touch – all of which helps you save money with vehicles that run better and last longer.
Only a microscopic film of oil separates metal surfaces in your engine from touching and causing wear. AMSOIL synthetic motor oils form a more durable fluid film than conventional oils due to their resilient base oils. They reduce wear and help you maximize engine life.
COLD 36% Easier & Faster Cold Starts When the temperature drops, motor oils thicken and move slower, causing parts of your engine to remain unprotected for a short period of time. AMSOIL is more fluid at cold temperatures than the tested conventional oil, giving you 36% easier and faster cold starts. * This means it can reach vital components faster, providing more immediate engine protection and reduced wear.
HOT 5x Cleaner Engines in Hot Conditions Vehicle manufacturers are altering engine designs to keep pace with increasingly strict fuel economy standards, resulting in engines that run hotter than ever. The average operating temperature is up to 235°F, and even hotter under heavy loads. This heat can quickly break down oil, leading to oxidation, sludge and deposits. Recent tests show AMSOIL keeps engines 81% cleaner* (5 times cleaner) than conventional oil by better resisting the formation of deposits.
The base oils used in conventional oils contain molecules of different sizes and weights as well as unwanted materials, like wax. This typically requires more energy to circulate throughout your engine, which can reduce fuel economy. Conversely, AMSOIL synthetic motor oils are formulated using molecularly uniform synthetic base oils that slip easily over one another and are free of unwanted materials. They help reduce energy lost to friction and maximize fuel economy.
If enough motor oil is consumed, eventually there may not be enough to reach all the complex parts of your engine, which can potentially cause damage.AMSOIL Signature Series 5W-30 showed 38% less oil consumption* than the tested conventional oil, requiring less-frequent top-offs.
AMSOIL products are Warranty Secure, keeping your factory warranty intact. They are high-performance replacements for vehicle/equipment manufacturer-branded products. You can also be confident that using AMSOIL synthetic lubricants or practicing extended drain intervals will not void your new vehicle or equipment manufacturer’s warranty. Get the Facts About Your Rights!
AMSOIL products are covered by the AMSOIL Limited Warranty. Like AMSOIL products, the AMSOIL Limited Warranty is built with an extra measure of protection. While some other oil companies guarantee their products only until you reach a specified mileage, we don't place restrictions on our warranty coverage based on total vehicle miles.
