This Gas and Oil Is Used in Pulsar Generators (2-Cycle & 4-Cycle)

The Pulsar generator’s engine is sensitive to the fuel it is fed, therefore it’s important to know what kind of fuel it takes to avoid injuring the machine.

Two-cycle engines like those used in pulsar generators need a 30:1 gas-to-oil combination.

  • Please use unleaded gasoline with an octane value of 87 or above and no more than 10% ethanol.
  • To a two-stroke air-cooled engine, add high-quality motor oil.
  • Before putting gas and oil in the tank, make sure they are thoroughly mixed.

The 4-cycle engines used by pulsar generators each have their own dedicated fill ports.

  • There is only one fueling option available, and it must be unleaded gasoline with an octane level of 87 or higher and no more than 10% ethanol.
  • There is only one SAE 10W-30 oil fill location.

It is recommended that you consult the Pulsar operator’s manual if you are unclear of the generator engine type. Remember to refuel in a well-ventilated area far from anything that could catch fire.

Incorrect or Old Gas Used in a Pulsar Generator

A generator’s poor performance is often the result of using old gas. Gas loses its potency and reliability as it matures.

Ethanol, which is present in nearly all gasoline, is a moisture magnet. After combustion, it leaves behind a varnish that clogs gasoline lines and corrosion that destroys engine and fuel components.

Never use gas with an ethanol percentage more than 10% due to the problems it causes.

Fuel stabilizers and new fuel should be used.

To avoid wasting money, you should buy gas only once every 30 days and use it up before it goes bad. If you want your gas to last a bit longer, try adding a gasoline stabilizer like Sea Foam Motor Treatment, which helps remove moisture from the fuel.

The consequences of stale fuel cannot be undone by fuel stabilizers. Stabilizers should be added to new gas.

Fueling Pulsar Generators Without Ethanol:

Fuels containing ethanol might damage the engine in a Pulsar generator, therefore you might want to switch to a different type of fuel. Just some gas stations offer this sort of fuel.

Gasoline and Diesel in a Two-Cycle Pulsar Generator

Pulsar Generator Fueled by a 2-Cycle Blend of Gas and Oil

Gasoline must be mixed with 2-cycle air-cooled premium oil before being pumped into the fuel tank of any 2-cycle Pulsar generator. Two-cycle generators can be damaged by using undiluted gas in them.

The car’s engine will seize up and stop working if you do this. Reason being, gas reserves are getting low. The engine’s internal parts won’t be able to move smoothly without the oil that is added to the gas as a lubricant.

If you start your generator after adding pure gas, it’s likely you’ll have to buy a new one. There is irreparable damage to the engine.

Your Pulsar 2-cycle generator calls for a 30:1 gas-to-oil ratio. This formula translates to 30 parts gas and 1 part oil. Please use the following chart as a guide during blending.

Unleaded gasoline with an octane value of 89 or higher (or mid-grade) and up to 10% ethanol should be used for this mixture. Add an ISO-L-EGD and JASO M345 FD approved premium 2-cycle oil for air-cooled engines.

Pulsar two-cycle generator fuel and oil ratios:

  • Prepare the correct amount of fuel mix by consulting the table below.
  • Take the top off a legal gas container. Fill a gas can with unleaded fuel (at least 89 octane and no more than 10% ethanol).
  • Add the 2-cycle oil to the gas can according to the chart’s recommended ounces.
  • Just put the cap back on.
  • The fuel and oil should be gently shaken together to combine them.
  • The fuel tank of the Pulsar generator requires more of it.

Petrol and Gasoline in a Four-Cycle Pulsar Generator

Four-Cycle Pulsar Generator Fuel

Several 2-cycle generators are still being produced by Pulsar, although 4-cycle engines power the vast majority of the company’s modern generators. There is no need to blend fuel and oil because these engines have dedicated terminals for each.

Unleaded gasoline having an octane value of 89 or higher and 10% ethanol content or less is required for use in 4-cycle Pulsar Generators.

A fuel stabilizer, such as Sea Foam or STA-BIL, should be added to gasoline to prevent it from deteriorating too quickly and to prevent the formation of sticky deposits and unwanted moisture.

Gasoline with a minimal amount of ethanol in it is fine to use, but it’s not the ideal choice. An ethanol-free gasoline is ideal for use in a pulsar generator, but it is more expensive.

Pulsar generator oil in a four-cycle engine

Unlike 2-cycle or even 3-cycle engines, 4-cycle engines feature dedicated oil and gasoline fill locations. With a 4-cycle motor, NEVER combine oil and fuel. Never attempt to run a 4-cycle generator on 2-cycle oil.

All of the engine’s moving parts need to be kept well-lubricated, and oil is the key to doing that. Using the incorrect kind of oil or not enough of it can lead to overheating, which prevents your generator from starting and could potentially destroy the engine.

When using an air-cooled engine, Pulsar advises using SAE 10W-30 oil.

To sum up

Your Pulsar’s generator efficiency is dependent on the fuel you use. Corrosion and fuel limitation are two of the problems that might arise from aging fuel.

Choose a fuel for your Pulsar generator by following these easy steps:

  • Never re-use gas that has been used before.
  • Check the gas and make sure it has no more than 10% ethanol in it.
  • Find out what kind of motor your Pular has (2-cycle or 4-cycle).
  • While refueling a 2-cycle vehicle, you must combine gas and oil.
  • Direct gas is used in 4-cycle engines.
  • Put in a fuel stabilizer to prevent the gas from deteriorating over time. Before putting to the gas tank, combine with petrol.
  • Keep gas in a secure, dry place, away from sources of ignition like paper, wood, or dampness.
