Types of motor oil include conventional, synthetic, diesel, bio-based, hybrid (blends of conventional and synthetic), and recycled oils. Motor oil varies in weight and viscosity, as well as additives that some manufacturers add to the oil during the refining process. A numerical code system created by the Society of Automotive Engineers (SAE) grades motor oils according to viscosity--the higher the number between 0 and 60, the more viscous (thicker) the oil is. Most consumer motor oils are graded by two numbers, with the first number indicating cold weather (Winter or "W") performance.2-Stroke Engine OilThis oil is specifically designed for 2-stroke (or 2-cycle) engines. 2-stroke engines are typically "total-loss lubrication" engines, meaning that this oil will burn up in the combustion chamber when the engine is on and will need to be replaced regularly. Common uses of 2-stroke oil are some motorcycles, lawnmowers, snowmobiles, marine outboard motors, and other small-engine devices.Conventional Motor OilThis oil is a conventional motor oil, meaning it is refined from crude oil or petroleum products. Conventional motor oils may or may not have additives included after refining. Conventional motor oils are more versatile than synthetic or hybrid motor oils, because they are suitable for use with nearly all types of modern vehicle engines, from cars and trucks to motorcycles, ATVs, farm equipment, and more.Racing OilRacing oils are designed for track cars and other types of high-compression vehicles intended for motorsports competition. They contain particular additives for increased engine horsepower and reduced friction on metal parts, and provide special protection for engines with high compression or higher horsepower. Racing oils usually include fewer detergents than regular conventional motor oils. Please note that many, if not all, oils labelled as racing oils are not street legal, and it is not recommended to put racing oil in a conventional passenger vehicle. Make sure to double-check the product label as well as the specifications of your vehicle to ensure proper usage.

  • The best
Size: 16 Ounce
I run RED LINE through all my machines and it’s always been the cleanest and best burning mix hands down. Minimal deposits left when broke down engines to rebuild worth every penny bottom line.

  • Maybe the best there is
Size: 16 Ounce
So back in the day when we ran 16:1 in our motocross and enduro bikes, the 2-stroke would burn, clouds of blue smoke. Well 2-stroke oil technology has greatly advanced and not only can we use less oil, but this stuff doesn't really burn, just vaporizes, which is a good sign of its durability and effectiveness. No cheap, but if you value your engines' lifetimes, this is the best I've found, nothing like the junk they sell at auto-parts or hardware stores. ... show more

I bought this for my mid 80’s Johnson 8hp outboard. It’s never ran so good!!! Never thought I would see such a difference in something that’s only 100:1 ratio.
