What is an oil injection system?
The oil injection system made applying oil to the engine very similar to the 4-stroke engine, which created a couple of immediate advantages to premix (which we’ll cover in just a minute). The typical injection system is simple in its operation.
How do motorcycle oil injections work?
The typical oil injection system is simple in its operation. The oil (usually a little over a quart for most bikes) is poured into the oil tank where it is fed to the oil pump. Instead of having only one throttle line, the bike will have two – one traveling to the carburetor and the other to the oil pump.
Are oil injectors unreliable?
This is where the legend of the unreliable oil injection systems got its start. And it persists even today, even though snowmobiles, personal watercraft and street motorcycles with 2-stroke engines have used injectors for decades.
How does a fuel injection system work?
There are 3 different systems, (a) Ficht (ex OMC & now Bombardier) is a german invention where the fuel is subjected to an impact shock (like dropping a stone into a full bucket of water, the resultant pressure/shock waves overflow the bucket), the pressure waves then get directly injected through a nozzle into the combustion chamber.
How does injection oil work?
0:020:412 Stroke Oil Injection - YouTubeYouTubeStart of suggested clipEnd of suggested clipWhere it will mix with the fuel and lubricate the internal engine parts the pump delivers theMoreWhere it will mix with the fuel and lubricate the internal engine parts the pump delivers the correct amount of oil for the engine speed and the throttle setting. Which makes it a more precise.
Is a 4 stroke oil-injected?
Four-stroke engines are lubricated by oil held in an oil sump. The oil is distributed through the engine by splash lubrication or a pressurized lubrication pump system; these systems may be used alone or together. Splash lubrication is achieved by partly submerging the crankshaft in the oil sump.
Are oil-injected outboards good?
Oil injection is a nice convenience and offers some performance advantages over a straight 50:1 ratio (or as recommended by your Outboard Manufacturer) especially if trolling for extended periods. Different methods of providing automatic lubrication have been developed over the years but they all have one problem.
How do I know if my outboard is oil-injected?
The only way to check the OMC system is to mark the level on the tank and see if it moves. Also if it is smoking, its oiling. If you ever disassembled a VRO pump and seen how it works, you would be able to see that the pump can't pump fuel without pumping oil also.
What does oil injected outboard mean?
With an oil injection system, the oil is automatically metered in with the gas. Not only do you not have to worry about the correct mixture, but you also don't have to mix the gas and oil you simply put each in its own tank and allow the system to do its job.
Is 2 cycle oil the same as injection oil?
While all two-stroke oils are compatible, they are not created equal. High-quality synthetic 2-stroke injector oils will create less exhaust smoke, offer improved performance, improved wear control and cleaner engine internals.
Is premix better than oil injection?
Many riders say that premix is the only way to go. It's far safer as you don't have to be afraid of an oil-injection system failure. It also gives you control over the mix ratio, a key advantage for racers and stand-up riders. On top of that, the lack of an oil-injection system also means easier maintenance.
How do I know if my 2-stroke oil injection is working?

Do you change oil in a 2-stroke outboard?
Being two-stroke engines, they have no crankcase oil to change, and have fewer moving parts than four-strokes; that means fewer parts that need maintenance, and fewer parts to fail.
Does a Mercury 2 stroke have engine oil?
Mercury® Premium Plus 2-Stroke Synthetic Blend Marine Engine Oil brings a specially formulated design with a marine additive package to meet the needs of low- to mid-horsepower outboard engines.
How do you bypass the oil injection on Polaris?

When did oil injection become popular?
As an alternative to premixing oil, oil injection systems became popular in America in the late 60s and early 70s when foreign-made motorcycles began dominating the market.
What is the difference between premix and oil injection?
The Difference Between Premixes and Oil Injection. Let’s go ahead and state the obvious – all internal combustion engines must-have oil to operate. However, specific engines receive their oil in different ways. For example, four-stroke engines receive their oil via the top of the engine. It then flows down to the oil pan ...
What are the advantages of 2 stroke oil injection?
The first advantage that sticks out in most people’s minds in regards to oil injection systems is the ability not to have to measure and premix oil with the gas every time you fill-up the gas tank. This is one of the main reasons why you’ll find old road bikes with injection systems.
How does a two stroke engine get its oil?
The common two-stroke engine (be it lawn equipment, dirt bikes, outboard motors, etc.) receives its oil via being mixed in with the engine’s fuel, called premixing. Depending on the engine, there will be a set ratio of oil that must be mixed in with the gas to achieve the proper lubrication. Get the ratio wrong, and you risk damaging the engine.
Why is it important to get the right oil to gas ratio?
With premixing, it’s important to get the right ratio of oil-to-gas to maximize engine performance and prevent potential future engine issues. And unless you run the tank to empty before filling up every time, this can prove to be quite tricky sometimes.
Is oil injection better than premix?
However, there are quite a few costly disadvantages to using injection versus premix. While taking good care of your dirt bike is mandatory to keep it running for years to come, it is far more tedious to keep an oil injection bike running smoothly, and the results of not doing so are much more costly.
Can you use 2 stroke oil in an injection system?
You simply pour the oil in its tank and the gas in its tank, and you’re ready to go. Keep in mind there are several types of 2-stroke oil out there; make sure you use an injection compatible formula.
What does "leaner oil" mean?
One final factoid to really confuse you, a leaner oil ratio = a richer gas to air ratio. That means the more oil you add to your gas, the hotter the engine runs because of the leaner jetting. As you have noticed Son, you are not getting my advice; I’m too smart for that. All I will give you are “Just the facts”!
What kind of oil did the Son 2 strokes use?
Here is some historical background Son. Originally all 2-strokes ran on pre-mix. And the oil was a petroleum based pre-mix rated oil, that never really burned clean. They also came equipped with atrocious ignitions that had so little electrical energy, they could barely jump a 0.020” sparkplug gap.
Can you mix gas with oil?
If you are intent on using pre-mix then you can mix your gas with oil at from 32:1 to as lean as some yahoo claimed he runs his 2-stroke! No matter what the pre-mix ratio, you will feed your Blaster’s engine too much oil at idle and a bit lean at full throttle.
1. Jet Ski Oil Reservoir
As a rule of thumb, each oil-injected jet ski has a separate oil reservoir mounted somewhere inside the hull.
2. Jet Ski Oil Pump
The heart of a jet ski’s oil-injection system is arguably the oil pump, driven by the engine with gears.
3. Jet Ski Oil Pump Cable
It’s safe to say that the oil pump is throttle-controlled on most jet skis, meaning that it’s connected to the throttle lever with a cable.
4. Jet Ski Oil Lines
The pump is connected to the engine and oil reservoir with rubber hoses, also known as oil lines.
5. Gauges
Jet skis typically feature an oil level gauge or a Low Oil warning light that tells you when the tank’s oil level drops too low.
