  3 Questions
Q: What is the shelf life of the diesel fuel in a diesel setup? What about fuel breakdown or water in diesel fuel as an issue? Is there fuel efficiency differences between diesel v. LP?
by Scott from Alabama on March 26, 2014

A: Shelf life for Diesel Fuel is about 6 months, but can be extended with a fuel additive.

It is recommended to discuss the additive with your diesel supplier for a recommendation.

Gillette's Engine includes a water separator, but an additive can also help.

Diesel is less expensive to operate, and new ones are more efficient.

Q: What is the fuel consumpion, gallons per hour estimate? Thanks
by Alan Kennedy from Missouri on January 16, 2013

A: Per the Gillette spec sheet:

100% LOAD - 2.8 (10.5)
75% LOAD - 2.1 (8.0)
50% LOAD - 1.4 (5.3)

Note: Ratings are estimates and can vary depending on altitude and temperature changes.

Q: Can I fuel this diesel generator from my home heating fuel tank?
by EF Jachmann from Connecticut on December 08, 2012

A: No, these units cannot run off of Home Heating Oil. True Diesel fuel only.
