Gasoline & Diesel

Make sure to fill up vehicles with fuel ahead of any expected severe weather
- As general backup for cars and thus transportations (medical, food, water, and other necessities, …)
- As indirectly source for recharging phones/tables
Also consider filling up extra tanks (lawn movers, for any generator, et c), but:
- Careful with storage and safety ordinances (by city, other), as poses an additional risk for fire if breaks during heavy storm
- And if have any of those pesky two-stroke engines around, Why?! Sorry, got carried away – just make sure to continue to keep gas tanks for two-strokes and four-strokes clearly separated.

	Diesel	Gasoline
Energy (e.g.¹)	10.7 kWh/l 138,000 Btu/U.S. gal	9.5 kWh/l 122,000 Btu/U.S. gal
	Less	More
Storage	6-12 months	3-6 months	Diesel has longer shelf life.
Flammable	Less	More	Diesel is safer in storage and general handling
Engine…
… cost	Higher	Lower	Diesels are more expensive to buy
… maintenance	Less	More	Diesels has simpler but sturdier design.
Example, generator	Generac XD 5500W Diesel Portable Generator	Briggs&Stratton 5000W Gas	More in our Generators section
cost to buy	US$ 3800	US$ 700	Yep, quite a difference (in this case)
tank size	12 gallons	7.5 gallons
runtime @ 50%	32.4 hours	12 hours	50% load is 2500 W for both generators
= gal/hr	0.37 gal/hr	0.625 gal/hr
gas for 24hrs	8.9 gal, 0.74 tank	15 gal, 2 tanks
gas for 1wk	62.2 gal, 5.2 tanks	105 gal, 14 tanks
