As the owner of outdoor power equipment, you naturally want to use the best oils for your equipment that is safe for use in its engine. Small engines need constant lubrication in its crankcase which engine oil provides. The engine oil is also necessary for keeping the engine cool. So if the engine oil levels are low or if you use the wrong oil in your machine, you end up with an overheated engine that tends to quickly shut down. With so many types of oils in the market and especially synthetic and conventional oils to choose from, you may need help finding the best oil for your small engine.

Factors to look out for
There are some basic criteria that your outdoor power equipment fuel has to meet. They have to be clean and fresh, and while oil with up to a maximum of10% ethanol or gasohol is acceptable, fuel containing 10% and more ethanol is not approved for use in small engines. And as gasoline refineries tend to raise and lower their RVP ratings based on the climate and temperature, you have to check the oil’s RVP rating before buying it. Summer fuel should preferably have a low RVP rating while winter fuel has a high RVP rating.
Never use any unapproved gasoline like E15 and E85, don’t mix oil in gasoline or attempt to run the engine on alternative fuels. Using wrong fuels in your engine only leads to damage to engine compartments which its warranty doesn’t cover. And remember that small engines also need regular oil changes like your vehicle. It’s recommended to change the oil in push mowers after every 25 hours of use and after 50 hours of operation in case of riding lawn mowers and lawn tractors. If you can’t change your oil as frequently as mentioned, at least change it every season, and clean and replace the oil filter if needed.
Synthetic oils are always a better choice
While conventional oils are effective for your small engine, the improved synthetic oils offer more benefits, making it a more popular and better choice for your engine. These oils offer better viscosity, wear and deposit control and low-temperature fluidity.
So the regular use of synthetic oils in your engine reduces the chances of it failing and thus in the process, extends its service life. The only disadvantage of using synthetic oils in your engines is that it’s more expensive than conventional oils. However, the many benefits of the oil make it’s increased rate worth the investment.
Differences between 2 stroke and 4 stroke engines
Now you know the importance of using the right oils for your small engines, you need to know that there are also some differences between two-stroke and four-stroke engines. The most significant difference between the two is its gas exchange process. In case of 2-stroke engines, there’s an expansion or power stroke in each cylinder during a crankshaft revolution. Both the exhaust and charging processes work together while the piston moves through the lowest centre position.
In case of a 4-stroke engine, the piston first displaces the burned gases with an upward stroke and fresh oil enters the cylinder during the downward stroke. Two complete turns of the crankshaft here make a power stroke instead of the single-turn in 2-stroke engines.
Synthetic oil for 2-stroke engine
2-stroke engines are generally lighter, cheaper to build than 4-stroke engines and produce a higher power-to-weight ratio. This is why they are popularly used in weed trimmers, outboard motors, chainsaws, off-road motorcycles and racing applications. And as these engines easily start in cold temperatures, they are ideal for snowmobiles too.
While some oil tends to accumulate under the 2-stroke engine’s crankshaft, these engines use a total-loss lubrication system combining oil and fuel for energy and engine lubrication. Oil and fuel combine in the cylinder’s intake tract while lubricating important parts like cylinder walls, connecting rods and crankshaft.
And it’s because 2-stroke engines don’t have a dedicated lubricant source like 4-stroke engines that they tend to wear out quicker than 4-stroke engines. This is why it’s better and important that you always mix high-quality two-stroke oils which reduce engine wear significantly. Examples are such high-quality oils are Royal Purple HP 2-C High-Performance 2-Cycle Oil 01311 and Amsoil 2-Stroke Synthetic Oil Saber, Professional Mix.
1. Amsoil 2-Stroke Synthetic Oil Saber Professional Mix
Amsoil is a brand famous for their premium synthetic 2 and 4-stroke engine oils. These oils produce great results in both recreational and work equipment. The same holds for Amsoil 2-stroke synthetic oil Saber professional Mix which improves the performance and protection of 2-stroke engines since 1973.
It’s meant for use in handheld pre-mix two-stroke power equipment including trimmers, brush cutters, blowers, chainsaws, edgers and shredder vacs. This mix solves the problem most owners and operators of power equipment face about exhaust smoke emitted from two-stroke engines mixing oil and gas in the right ratio. It also works well at preventing wear ang tear, possible engine failure and many more issues of 2-stroke engines. Amsoil Saber Mix is perfect to use in air-cooled engines that’s pre-mixed as it can tolerate extreme heat and pressure and thus protects engines from wear and tear and dangerous deposits.
This perfect lean mix ratio of 100:1 is in fact called the SABER ratio. This ratio is very helpful at you no longer have to keep mixing fuel and oil in different ratios to use in different equipment. It also plays a vital role in ensuring engines are practically smokeless when in use. Amsoil Saber Protection in your small engine considerably reduces wear and tear, and friction. It is perfect for use in hot-operating two-stroke engines as it reduces or practically eliminates any carbon or deposit formation on exhaust ports and ring sticking.
There’s also no worry about off-season storage or adding any fuel stabilizer with Amsoil Saber. It stabilizes fuel to prevent it from deterioration during storage and triggering poor engine performance. Its anti-rust formulation is also very helpful and important at resisting rust in the damp environments most two-stroke applications are found. And with its smokeless operation, the formulation burns clean to pass the industry’s smoke test. This low-emission property makes this oil perfect to use in equipment where operators are constantly subjected to fumes and smoke.

2. Synthetic oil for a 4-stroke engine
Four stroke engines tend to produce much more torque even at a low rpm. It is this feature of these engines that improves the durability of equipment when compared to high-revving two-stroke engines. With its lower emissions, the oil boasts of improved fuel efficiency. It is because of all these traits and reasons that four-stroke engines are most popularly used in applications like ATVs, motorcycles, lawn mowers and even personal watercraft.
Unlike two-stroke engines where the oil and fuel have to be mixed, there is no mixing of oil in gasoline in four-stroke cycle engines. You, in fact, should not even modify the engine to run on alternative fuels. This only damages the engine components and in the process voids the engine’s warranty. This is why you should use the best engine oils for your four-stroke engine like Briggs & Stratton SAE 5W-30 Synthetic Small Engine Motor Oil – 32 Oz. and
