Are cold starts bad for diesels?

- Just 0.4 percent coolant containing glycol in diesel engine oil is enough to coagulate soot and cause a dump-out condition leading to sludge, deposits, oil flow restrictions and filter blockage.
- According to one study, glycol contamination results in wear rates 10 times greater than water contamination alone.
Can you lean out a diesel?
Diesels are a lean burn engine, hence the efficiency. They operate in an excess air condition all the time and no you can not lean it out and melt it down like a gas engine.
Will sugar ruin a diesel engine?

Will a diesel start without glow plugs?
Yes, a diesel engine will run without glow plugs. In fact, many diesel engines DO NOT EVEN HAVE glow plugs, and they run. Glow plugs are not an integral part of the diesel engine operating cycle: rather, they are merely a starting aid that some engines are equipped with.

- Use Fuel Additives. …
- Change the Oil.
Do diesels use fuel when idling?

Is it OK to let a 6.0 Powerstroke Idle?
Idling for a while shouldn’t be a problem, as long as afterwards you run it up to WOT a bit to clean it out, excercise the VGT Vanes, and burn off the gunk with some nice high EGT’s. Idling for 30 minutes, followed by just shutting it off, IS bad. Gotta clean out all that gunk before shutting it down.
How long can you let diesel sit?
Under ideal conditions, diesel fuel can be stored between six and twelve months. To extend the life past twelve months, even under the best conditions, it needs to be treated with fuel stabilizers and biocides.

Is it better to run a diesel lean or rich?
We use lean mixture in diesel engine. We know that diesel is less volatile as comapred to petrol so it is difficult to atomize the fuel during injection. There are certain advantage as well as disadvantage of running the engine at lean mixture. Almost same amount of power by burning less amount of fuel.
What causes black smoke in a diesel engine?
The black smoke is composed primarily of elemental carbon from incomplete combustion of diesel fuel and traces of engine lubricant. … Over-fueling can be caused by diesel fuel injector wear that enlarges the nozzle hole or erodes the injector needle and allows excess fuel to flow into the combustion chamber.
