According to most refiners, diesel has an average shelf life of 12 months if stored at a temperature below 20°C (68°F). That may be realistic for underground storage tanks, but not for aboveground storage facilities. If temperatures reach above 30°C (86°F), shelf life is 6-12 months at best.
How long does diesel fuel last?
Diesel fuel can last twice as long, around six to twelve months. The reason these numbers are so broad is that it’s hard to tell how old the gas actually is. It may have been sitting inside the gas pump for a month already before you came to fuel up.

Does diesel last longer than fuel?
Correlation between High Emissions and Low “Gas” Mileage It takes 30 percent less diesel for a compression engine to travel the same distance as a gasoline spark-fired engine. That means a diesel engine propels a vehicle or machine considerably farther/longer on the same quantity of fuel.
How long does diesel last?
Diesel, like petrol, is a fuel that can expire. It’s important to store diesel fuel in a container designed to block out heat, water and air, which can speed up the expiry process. Under the right conditions, diesel can last up to twelve months, but by adding a diesel fuel stabiliser, you can make it last even longer. 6
Is a diesel engine better than a gasoline engine?
“ In fact, to some degree, some people who drive diesels find they perform better than gasoline engines.” That’s because diesel-powered engines get their best power when the engine’s revolutions per minute ( RPM) are low—that is, at speeds below 65 miles per hour, where most driving takes place.
Does diesel go bad?
Diesel does not necessarily go bad due to lasting too long. If you store diesel fuel correctly, it can last for almost a year without issue. However, there are a few things that can cause your diesel to go bad prematurely. 1. Water and Oxygen The reduction of sulfur levels in diesel has made it more susceptible to water contamination.
Stored diesel used to last for years – nowadays its shelf life is measured in months. Diesel fuel eventually goes bad, that’s just a fact. Three things speed up the natural process of good fuel gone bad – water, air, and warmth.
Why do gasoline engines wear out more than diesel engines?

Why don’t we see more diesel engines?
This is why gasoline-powered engines experience more wear and tear, at lower mileage. Why don’t we see more diesel engines? In 2030, 75% of new vehicles will still have a combustion engine on board.
Is a diesel engine better than a petrol engine?
Because diesel engines offer better fuel economy they can be considered to be better for the environment.
