Best 2 Stroke Outboard Oil of 2020

Best 2 Stroke Outboard Oil of 2020

Your outboard motor is a significant investment, and you need to protect it with the best 2-stroke outboard oil you can buy. Marine motors face unique stresses, from sitting idle for extended periods in wet, salty conditions to extended runs at maximum revolutions. There are times when it makes sense to economize on consumables, but this isn’t one of them. If your oil isn’t up to the job you could quickly find yourself facing large costs for repair or replacement of an expensive motor. 

Not all oils are ideal for all engines. Older carbureted and electronic injection motors used standards that differ from those demanded by modern Direct Fuel Injection (DFI) outboards. Some oils can be used by more than one engine type and others are specific to a single type of engine. You’ll need to choose an oil that meets your engine requirements, working conditions, and budget. This list of the best 2-stroke outboard oils should get you started!

BEST FOR EVINRUDE E-TEC OUTBOARDS

Evinrude’s E-Tec outboards are among the most modern and popular marine engines on the market, offering an unmatched combination of high performance, low fuel consumption, and low emissions. This oil is specifically formulated for use in E-Tec outboards, offering protection against friction and wear with minimal combustion deposits. This is a clean-burning oil that is almost entirely smokeless, ashless, and odorless.

XD100 oil can be used in any DFI outboard but is most appropriate for Evinrude’s E-Tec motors. An E-Tec outboard can be reprogrammed by a dealer to minimize oil consumption, but after reprogramming they can only operate reliably with XD100 oil.

THINGS TO CONSIDER WHEN BUYING A 2-STROKE OUTBOARD OIL

 

QUALITY COUNTS

There are many cheap oils available in stores that claim to be suitable for marine use. Many of these are just repackaged general-purpose oils. An outboard motor is a significant investment and the quality of the lubricants you put in it has a real effect on the engine’s lifespan. Inferior oil may be a few dollars cheaper, but if it leads to early repair or replacement of an expensive outboard, the savings really aren’t worth it. This is one case where quality really does matter.

 

KNOW YOUR OUTBOARD

In 1998 the EPA mandated that between 1999 and 2006 a new set of emissions requirements would be imposed on marine outboards. Prior to 1999, almost all 2-stroke outboards on the market were carbureted models that left significant amounts of fuel unburned. 

Carbureted engines required mixing oil with the fuel before use. As the new regulations were implemented, manufacturers moved to Electronic Fuel Injection and later to Direct Fuel Injection (DFI) systems. Almost all modern outboards are DFI, but many older outboards are in circulation. 

Some outboard motor lubricants are specific to one type of engine, others can be used with more than one type. You should know what type of engine you have and choose an oil that’s appropriate for that type.

SPECS AND FEATURES EXPLAINED

 

BASE TYPE

The base type refers to the oil compound before blending with additives. Oil bases are either conventional or synthetic. Conventional-base oils are markedly cheaper and high-quality conventional-base oil is adequate for most purposes. Synthetic-base oils typically have fewer impurities and thus leave fewer deposits behind in your engine. Synthetics also flow more smoothly on cold engine starts. Most outboards can use either conventional or synthetic-base oils, but check your manufacturer’s recommendations for guidance on the specific requirements of your motor.

 

RATING

The TC-W3 rating is issued by the National Marine Manufacturers Association. To earn the rating oils must pass a variety of tests for piston deposits, piston ring stickage, and lubricity. Any oil used in an outboard motor should carry a TC-W3 rating.

 

MANUFACTURER’S SPECIFICATIONS

Each manufacturer has lubricant specifications and using oil that fails to meet those specifications may void your engine warranty. Most high-quality oils are formulated to meet all major-manufacturer warranty standards, but it can’t hurt to check your manufacturer’s standard and be sure to use oil that meets it, especially if your outboard is still under warranty.

 

PERSONAL WATERCRAFT

Personal Watercraft are small jet-powered boats that you sit or stand on, rather than sit in. Many people call them jet skis. Some general-purpose lubricants may be suitable for both outboards and personal watercraft, others are not. Check the specifications on your outboard oil before using it in a personal watercraft.
