Teach you how to distinguish the authenticity of construction machinery oil
At present, the engineering machinery oil on the market is mixed, fake and shoddy construction machinery and diesel oil is flooding is not poor, use regular attendance and service life of oil engineering machinery have important effects. Here is a brief summary of the experience of identifying the oil and diesel oil used in construction machinery, hoping to provide a reference for the majority of users in the selection of oil products.
Identification of diesel oil authenticity
Inferior diesel common has two kinds: one is the oil dealers from private oil at low prices to the production of these small oiler diesel are generally not up to the national standard; the two is buying diesel after themselves against water damage such as oil on sale, the machines are often more.

Comparison of true and false diesel
See color: qualified diesel to clear, transparent, color is generally light yellow or greenish yellow. Such as the discovery of muddy, dark, black, colorless or partial, for the unqualified.
Smell: qualified diesel oil exudes greasy taste and pungent flavor, unqualified diesel oil in addition to the original flavor of diesel, but also smell.
Shake: take a transparent cup, load a small amount of diesel, and then shake, qualified diesel will appear a large number of foam and soon dissipate.
Static observation: transparent glasses with a small amount of diesel, static observation after 1-2 minutes. Qualified diesel oil will not appear impurities and sediment, to observe whether the diesel oil mixed with water (diesel density is less than water, water mixed with diesel after static, and water will be obvious fault, it is easy to see.)
If you have the qualifications, when you buy diesel, or to PetroChina, Sinopec and other large suppliers to buy.
The way to identify the authenticity of engine oil
Fake oil on the market there are three types: one is the use of recycled waste oil after purification treatment after filling listed; two is the use of mixed base oil alone, without any additives, in order to lower cost; three is the purchase of low-grade oil filling, shoddy. They usually adjust the color of false lubricating oil to the real oil, which makes it difficult to distinguish from genuine appearance.
1, check the oil packaging, the regular manufacturers of oil drums will generally have the security code or two-dimensional code, call the hotline to check the security code to identify genuine manufacturers on drums, two-dimensional code scanning, can also view some information about the oil price for reference, and suggestions. Carefully observe the logo and seals on the barrel packaging, whether the words are clear, whether the color is pure, many fake oil packaging words and logo are more or less flawed, can not do 100% similarity.
2, observe the oil, oil really shallow and transparent, no impurities, no suspension, no deposit, good liquidity sloshing. False oil or oil deep, or impurity precipitates, or strong irritant, less liquid sloshing, or touch a drawing phenomenon.
Finally, recommended that users in the purchase of diesel oil, engine oil, hydraulic oil and antifreeze, choose the regular supply of oil to buy oil companies, after all, not much money, then the machine problems The loss outweighs the gain. If you choose a supplier, don't change it at will. If you have a problem, you can find the reason.
Inferior oil for construction machinery products great damage, if possible or use the original oil, such as the limited conditions, but also to polish his eyes, let those unscrupulous oil dealers have no place to hide. The above content is the summary of the identification of true and false oil, diesel several small methods, intended to attract a lot of attention, there are omissions, but also hope that everyone corrected.
