Yamaha EF2400iSHC - 2000 Watt Inverter Generator (CARB)

Yamaha recommends using 86 Octane fuel or higher. This unit does not require any mixing of gasoline or oil. Owner's Manual.

Yamaha does not offer a fuel conversion for any of their generators and adding an aftermarket one will void the warranty.

The Yamaha portable generators are engineered and warranted to operate on gasoline only. The reason your customer is burning through oil is due to the excessive temperatures of the unit.

Gasoline burns at 485 degrees F whereas propane burns at 1008 degrees F which will cause excessive heat within the engine in turn burning off the engine oil.

Thanks for your inquiry.

The Yamaha High Current model is not compatible with parallel cables. We do offer the EF2000iS Parallel kit which will give you 4000 watts surge and 3200 watts running when using the 30-amp outlet. Below is a link to this kit.

You will find the oil recommendations on page 24 of the owner's manual....

Recommended Engine Oil:
A. YAMALUBE 4 (10W-40),
SAE 10W-30 or 10W-40
B. SAE #30
C. SAE #20
D. SAE 10W
Recommended engine oil grade:
API Service SE type or higher
Engine Oil Quantity:
0.6L (0.63 US qt, 0.53 lmp qt)

Yamaha does not recommend any synthetic oil in their recommendations.

An inverter generator is a power generator that can process raw power into a power feed similar to the power received through power lines. The generator part of an inverter generator is usually powered by gasoline or diesel fuel. "Inverter" means that the power is converted from direct current (DC) into alternating current (AC).

Typically inverter generators are much smaller then standard open frame style generators and tend to operate at very low noise levels. This makes them perfect for tailgating or camping and in some cases able to power one or two items in your home in an emergency.

This model is too small for 50A output and in come cases it can be too small for 30A output.

This model is capable of producing 17A with a little surge capacity beyond that. It does have the capability of starting "Most" 13.5 BTU RV AC units when using a 20A power cord connected to a 30A RV connection with an adapter.

The EU3000ISEB is a better choice for output capacity and comfort due to its boost capacity and overall running capability.

Yes, all the Yamaha generators have a fuel valve shutoff allowing you to run the carb dry.

You need to us a 20A cord that matches the 120V - 20A outlet to pull the maximum out of the generator.

The Honda EU3000isA and the 2 Yamaha 2800 watt generators are electric start. Click the links below for additional info:

The best thing to do is to calculate the starting amperage of the pump to find out what you need exactly. The formula to calculate wattage is - Starting Amps x Volts = Watts. Then you can determine the size that would suit your needs without purchasing something that may or may not work.
