E85: Ethanol/Gasoline mix. E85 in not approved for use in any Cummins Onan gasoline generator and will not function on this fuel.

ULSD: Ultra Low Sulfur Diesel. This fuel is now available across the country. 2007 and newer model diesel motorhomes are required to use it for the main propulsion engine. Cummins Onan generators will function properly on ULSD with no change to performance or maintenance intervals.

B5: 5% bio-diesel. Our Diesels are capable on running up to B5 (5%) bio-diesel. There are no changes to performance or maintenance requirements.

It depends on the model and the total power demands of other appliances you are running at the same time. But in general, smaller Cummins Onan generator sets can operate one air conditioner with power to spare. Larger models such as the Quiet Diesel Series of generators can power two or three air conditioners at a time. Visit our Generator Selector to find the generator that meets your power requirements.

Yes, your generator will perform better if you follow the break-in procedure recommended in the Operator's Manual. This typically involves running the generator at about 50 percent load for two hours, then at about 75 percent load for two hours, then letting it cool down. You should change the engine crankcase oil after the first 20 hours of operation, and every 100 to 150 hours thereafter. See your Operator's Manual for advice specific to your model.

Supercharging is compatible with all types of fuels including flexible fuels, i.e. CNG (compressed natural gas), propane, etc.

There's a discussion of different types of alternative fuels on this website, which includes advantages and disadvantages of each.

The Alternative Fuels Data Center's Alternative Fueling Station Locator can help you find alternative fueling stations in your area.

Yes, it will work on gasoline, diesel, but the percentage of improvement differ from one type to the other.

How long does a diesel engine/car typically last? (an 80's gas car would generally be on its last legs, but this doesn't seem to be so for a diesel)

Tests have demonstrated superior results when EMP? or EMD? or used with alternative fuels. EMP? and EMD? reduce exhaust emissions, save fuel, reduce carbon build-up, increases lubricity, lower NOx, and thereby increase engine efficiency. Unlike some alternative fuels, EMP? or EMD? can help a vehicle start easily in cold weather.

Our cars are powered by a gas engine that gets 60+ MPG. A full tank of gas will usually give a 60 mile range. We are hoping for an electric version in the future.

Because of the way diesel engines are built they will last many times longer than a gasoline powered engine. Diesels are far more efficient, as well. Though the energy used by a single light is small, if you use energy-efficiency practices with all your lights, the savings can add up. To reduce your lighting costs, consider: Installing controls such as timers, time clocks or photocells to ensure that exterior lights are turned off at the appropriate time.

No. Propane-powered forklifts actually have a cost advantage over electricity-, diesel- and gasoline-powered forklifts. In addition to propane-powered lifts' lower purchase price, studies have shown that propane engines last longer than other engines and require less maintenance over time, resulting in even greater savings.

On a gallon-for-gallon basis, ethanol delivers less energy than gasoline. However, today's vehicles are designed to run on gasoline blended with ethanol in small amounts (up to 10%) with no perceptible effect on fuel economy Flex-fuel vehicles designed to run on higher ethanol blends experience reduced miles per gallon, but these engines can be tuned to minimize detrimental effects on fuel economy

Massport offers a 50% discount per outbound trip for commercial vehicles that have operating agreements with Massport. This reduces the fee from $3.00 to $1.50 for Limousines and Shared Ride Vans, which is a significant discount for operators making frequent trips. The discount for courtesy buses reduces the per-trip cost from $3.50 to $1.75 per trip.

Installing panels around the generator to reduce noise levels is not advisable. The engine is air cooled, and restricting the access of cool air to the engine will reduce the life of the engine. Placing a barrier between you and the noise can deflect a majority of the high frequency noise and reduce noise levels. A simple sand filled cinder block wall the height of the generator can significantly reduce noise levels (taking care not to reduce cooling airflow).

Cummins Westport's B Gas Plus and B LPG Plus are EPA certified for non-road applications excluding power generation and marine applications. For further information contact the Cummins Westport Sales & Marketing Representative in your region. In addition, Cummins Power offers natural gas powered engines for all applications.

Some automakers have recently been building E85 capability into all instances of certain of their models; for example, all 2003 DaimlerChrysler vehicles (cars and minivans) with their 3.3-liter V6 engine can run on E85. However, in general a vehicle must be tuned to use ethanol; its requirements for fuel-air mixture and spark timing, in particular, are significantly different from those for gasoline.
