The difference between semi-synthetic and “real” synthetic oil

What is the difference between a semi-synthetic motor oil and a synthetic motor oil? A mineral oil, or conventional motor oil, is an oil that is refined or extracted through other means from crude oil. Crude oil is composed of a great number of differing hydrocarbon structures, each having their own characteristics—some of which are not helpful for lubrication and considered contaminants. For example, mineral oils contain wax that needs to be minimized or removed. Wax works great in candles but not in a motor oil. The objective in refining is to remove these contaminants and separate the hydrocarbon structures […]

The Benefits of Synthetic Oil Versus Conventional Oil

Your choice of motor oil will dictate if your vehicle will continue providing top performance for the longest period of time possible. By and large, you get superior performance when synthetic oil is used in all of your vehicles. This includes cars, trucks, recreational vehicles, motorcycles and other specialty vehicles. While some people might not understand the term synthetic oil, they should know that it is regarded as being the superior choice under most circumstances. Components Conventional motor oil is mineral in content and refined from crude oil. Thick conventional oil breaks down faster compared to synthetic oils. This can result in the […]

Comparing Synthetic Oils – Finding the Better Brand

Synthetic oil outperforms conventional motor oils in cars, trucks, recreational vehicles, marine outboard motors and even lawn mowers—anything that has an engine. Synthetic oils are engineered from chemical compounds. But not all synthetic oils are created equal. Each manufacturer of synthetic oil, including AMSOIL, has its own formulations. Blended oils Conventional petroleum products can be blended with synthetic oils to improve performance in your vehicle and cut down on sludge and generally improve performance. This is less expensive than 100% synthetic oils but blends are usually not as effective for preventing wear and the build-up of residue, and do not […]

AMSOIL Introduces NMMA Certified Synthetic Blend 25W-40 Marine Engine Oil

AMSOIL’s philosophy is to provide customers premium protection while still comporting to OEM recommendations in owner’s manuals. AMSOIL 25W-40 Synthetic-Blend Marine Engine Oil is formulated specifically for Mercury* and Mercruiser* motors that encourage the use of synthetic-blend oil. Mercury owner’s manuals actually discourage the use of full-synthetic oil. Since Mercury is the market leader and most Mercury owners won’t consider straying from these guidelines, AMSOIL 25W-40 Synthetic-Blend Marine Engine Oil was developed to give Mercury and Mercruiser owners a high tech upgrade while paralleling Mercury recommendations. Use in gasoline-fueled four-stroke inboards, outboards, inboard/outboards and personal watercraft that require any of the specifications […]
