It is true that diesel engines use barely any fuel while idling, far less than a gasoline engine. … While it isn’t particularly bad for it, there just isn’t much reason to do it; most diesels start perfectly fine when cold, warm up in a reasonable time, and don’t have gelling issues.

Is it bad for diesels to sit?

Letting an engine idle actually does more damage to the engine than starting and stopping. Running an engine at idle causes twice the wear on internal parts com- pared to driving at highway speeds.

Well, without diesel fuel additives, diesel can go bad in as little as 30 days before this oxidization process becomes unwieldy, creating deposits that can damage fuel injectors, fuel lines, and other system components which will hurt fuel economy and performance.

Why can diesels idle for so long?

They let them idle to prevent wear. Shutting them down causes more wear then leaving them running. Especially with the turbo, the turbo depends on the oil flowing through to cool the turbo bearings.

Can bacteria grow in diesel?

Microbial growth can occur in any diesel fuel. Biodiesel, being made from plant and animal fats, makes especially good food for these bugs and contributes to the increased incidence of biological growth problems seen in recent years. Bugs can grow in petro diesel as well. Stagnant fuel is especially at risk.

Registered. As long as you get it up to operating temperature for a few miles each way to boil off any fuel or condensation in the oil, you’ll be fine.

Diesel fuel can only be stored from 6 to 12 months on average — sometimes longer under the best conditions. Generally, to prolong the life of the quality of stored diesel fuel, it should be: Kept cool at around 70 degrees Fahrenheit; Treated with biocides and stabilizers.

Can I leave my diesel running all night?

Diesels are durable engines anyway, and a semi driver who lets his engine idle overnight to keep warm can still expect to get hundreds of thousands of miles out of his engine. Even so, idling for extended periods of time isn’t good for your engine. turning it off simply doesn’t exist with a modern diesel truck.

Should you warm up a diesel engine?
