Do excavators always crave small discounts when adding diesel?
Be careful of the money saved, it will eventually turn into engine maintenance costs!
Poor quality diesel is like "gutter oil", with good short-term prices,
After long-term use, the fuel injector wears out and the power decreases
The device frequently gets stuck
These troubles can make you cry out in the repair shop.
But don't panic! Today, I will teach you 6 tips for "sharp eyes and golden eyes",
You can distinguish the quality of diesel in minutes,
Even a novice can instantly become an expert in oil detection
1, Look at your face: Diesel also has a 'healthy color'
Qualified diesel comes with a 'refreshing filter'
The color is clear and transparent, and the bottom of the bottle is clean,
No impurities or floating objects, like a transparent amber colored drink.
If the color turns black like ink,
Or cloudy like milky white rice soup,
Don't hesitate, just pass!
These two are indeed the "identity cards" of inferior diesel.
Summary: Poor quality diesel has a black or milky white color,
Qualified diesel is clear in color, free from impurities and floating debris.
2, Smell: What is pungent are all "dangerous goods"
Qualified diesel has a good temper,
Upon closer inspection, there is only a faint smell of oil, which does not prick the nose.
But low-quality diesel often speaks harshly
Either with the momentum of kerosene,
Either it has a burnt smell,
There is even a foul odor,
Smelling it can make you furrow your brow.
Encountering someone with such a 'hot temper', quickly avoid them!
Summary: Qualified diesel has a light odor and no pungent smell;
Poor quality diesel may have pungent odors such as kerosene smell, burnt smell, and foul odor.
3, Shake it: Fast disappearance of bubbles is reliable
Shake the diesel cylinder into a 'disco scene',
Observing bubbles:
The bubbles of good diesel fuel are like acute particles,
It disappeared with a whoosh,
The traces hanging on the bottle wall are also faint;
The bubbles of inferior diesel fuel are slow,
After half a day without dissipating, there was still a layer of "oil film" hanging on the bottle wall,
Like a troublemaker who refuses to leave.
Summary: The quality of bubbles disappearing quickly after shaking is better;
The slow disappearance of bubbles and severe cup hanging do not meet the quality standards.
4, Filter one: Impurities have nowhere to hide
Find a filter paper and drop a few drops of diesel to make it "breathable".
After filtering high-quality diesel, the filter paper is clean and tidy,
Almost no impurities can be seen, like freshly washed face;
Poor quality diesel, once filtered,
Black and dirty things immediately appeared on the paper
These are all 'invisible killers' that damage the engine!
Summary: The residual black substance on the filtered filter paper is low-quality diesel containing impurities;
Almost residue free quality is good.
5, Let it go: Layered structures are absolutely not necessary
Let the diesel stand for a period of time,
Just like letting it 'sleep'.
Good diesel sleeps soundly, evenly up and down, with no significant changes;
Poor quality diesel will 'split':
There is a layer floating on top and a pile of slag sinking underneath,
Even white layers appeared, clearly indicating the presence of the disease.
Summary: Stratification occurs after standing still
There is a lot of sediment at the bottom
White layered diesel is of poor quality.
6, Professional test: If you can't figure it out, find a 'judge'
If you're not sure about the first 5 moves, don't hesitate!
Directly send the oil sample to a professional testing institution,
Let the instrument issue the judgment.
Spending some testing fees is more cost-effective than engine overhaul
The engine is the same as the human being. Only by eating and drinking well can we work awesome.
Don't let low-quality diesel destroy your equipment,
Quickly save these 6 moves,
Next time before refueling, flip it out and compare it,
Easy and cost-effective!
