Advantages And Disadvantages of Diesel Fuel - GlobeCore

Diesel fuel as well as other fuels is not ideal, therefore, it has both its advantages and disadvantages.  Before you buy one petroleum product or another, getting to know with its string and weak points is a good idea.  This will help you make the fullest use of its advantages and reduce the effects of its drawbacks. So, let’s begin.

Please visit our website for more information on this topic.

For a long time the basic value of diesel fuel was in its price, which used to be lower than that of gasoline.  It was especially advantageous for fleets to acquire such fuel due to the bulk volumes of use, which helped to make tremendous savings.  But by this day the price of diesel fuel has increased slightly, which makes us look for its other benefits.

Diesel fuel emits such harmful substances as nitrogen dioxide, nitrogen oxide, carbon oxide, sulfur dioxide and carbon black (soot). But their number less than other fuels. Therefore, there is some cost saving on a variety of environmental charges and fees.  Another feature of diesel fuel is its safety.  Diesel engines are designed so that high flammability limit of the oil product can be maintained.  That is why diesel fuel is preferred when fuelling military combat vehicles, battle tanks in particular.

Due to the high efficiency of diesel fuel it is quite economical, so regardless of the type of transport, in which it is used, the number of additional refills is minimal.

Having good lubricating properties, diesel fuel has a positive effect on moving parts of engines, increasing their reliability and extending engine lifetime.

Speaking about the disadvantages, they are caused mainly by the chemical composition of diesel fuel.  So, one of the problems is increasing oil viscosity at low temperatures.  At minus twenty degrees Celsius it is getting hard to pump the fuel and ignition problems occur.  But it is no longer critical, as we already have solutions that allow the use diesel fuel even in arctic climate.

Cheap and low-quality fuel grades have a lot of substances with poor combustibility, which results in their deposition on the surfaces of engine components, and the corrosion of such surfaces.

Also it should be noted that diesel engines typically produce more noise during operation than gasoline ones.  And the smell of burnt diesel fuel is rather unpleasant.

During storage, diesel fuel can be oxidized, become contaminated with harmful impurities and darken.  This complicates its use in automobile engines, so this fuel should be subjected to a specific treatment in order to restore its original properties.

To solve this problem GlobeCore company has developed and manufactures UVR plants.  They allow cleaning and brightening of diesel fuel, as well as removing aromatics mercaptans, hydrogen sulfide, and some sulfur.

While I was waiting for my bill, I saw one of the attendents tending to a motorcycle. He was changing the engine oil - after draining the old oil, he poured a liquid into it from a pet bottle - the liquid looked like diesel . since the plug was open, all the diesel flowed down. After pouring through about a fourth of a liter, he losed the plug and poured another around 250 ml. he then proceeded to gently kick the starter pedal!!
By now I was intrigued and wanted to know if it was diesel and he confirmed yes. He went on to add that this was the cheapest way to flush the engine off all old oil. What he did next blew me off - he kicked hard, let the engine fire and run for about half a minute before killing it and draining the oil mixed diesel. When I pointed out to him that this could harm the engine as diesel would get into pockets from where it can't be drianed he said "Saar no problem. that will be just a few tens of ml of diesel and if that mixes with a can of new oil nothing will happen

Gurus, is this right? Isn't what he did likely to harm the engine?

@Mods: Not sure if this is the right place for this thread. If not please move it to the right one. BHPian  
Join Date: Nov Location: Mumbai Posts: 749 Thanked: 49 Times It was engine flush that caught my attention, a friend has bought an esteem done just kms, it runs really coarse, had thought of suggesting to go for an engine flush. Nulon and Abro are two makes that i see in the market. But as its not suggested what could be a remedy ?

The car stalls in the first gear for less than rpm. Is it because its a BS3 esteem or clutch problem. Only 1st and reverse there is an issue.

Please suggest or advice. BANNED  
Join Date: Apr Location: Pune Posts: 1,200 Thanked: 885 Times Hi all, I have used Diesel as engine flush in old Diesel engines as follows
1) drain the old engine oil when the engine is hot or after a long drive preferably
2) let the engine cool down
3) fill up diesel only up to 2/3's of oil capacity
4) run the engine at Idle for 30 seconds max.
5) drain the diesel completly. ( keep it like this for at least half a day,so that diesel drains completly )
6) change oil filter & fill oil when the engine is cool.
this is a time consuming process.
( many times I have used this before overhauls of engines to get rid of the black carbon sooth, gives good results)

This is Not to be done frequently

I have never used this for petrol engines
May be I will use this method as last resort ( Suppose vehicle gets submerged & water /dirt gets in ) & when opening the engine to cleanup is not possible
This may be used to clean old & unused engines without opening them .
I dont think diesel does much harm .( the distributer pump uses diesel as its own lubricant in diesel vehicle ) but using petrol only ( without small amount of oil sounds risky.
Anyways I will not use Kerosine for such purpose anytime.

Draining oil after long drives is a best Idea

He said it will drain itself out in a few minutes and indeed I felt a definite improvement... must be in my head!! Distinguished - BHPian

The benefit of using diesel over petrol is that petrol posses a higher risk of catching fire if used as engine flush, as all engines need be operated at-least half a minute for the flush to be effective.

But IMO, the correct way of doing an engine oil flush is to use respective fluids available in the market. When I had switched from normal to synthetic oil in my bike, the mechanic used some 'engine flush fluid', but then I don't remember the details. BANNED

Petrol hardly has any lubricating properties, and there is a huge risk in blowing off all your engine gaskets .

While Diesel has lot of oil content, its a good lubricant and also a good flushing agent. But this method is not recommended, but most of the flushing agent you get has the similar characteristics and is derived out of Diesel

I use 250 ml abro to flush out old oils, but on the other hand, if you cultivate the habit of changing the engine oil every kms, you dont even need to use flushing agents. I do it so every kms i flush the engine, be it petrol or Diesel engine.
