Truck maintenance requires caution: beware of 5 types of fake parts on the market


Currently, the automotive parts market mainly sells three types of products: genuine parts, secondary parts, and counterfeit or substandard parts. What we commonly refer to as fake parts are those produced by unscrupulous merchants seeking higher profits, who imitate well-known brand automotive parts or original manufacturer parts. Although the appearance may be very similar, the quality is far below standard, which not only affects the normal lifespan of the vehicle but also poses certain safety risks while driving.

● Five Most Common Fake Parts You Need to Watch Out For

The domestic market for "fake parts" almost covers every component of a vehicle. Here, we will discuss the most common ones that are also the most deceptive.

1. Fake Engine Oil Seriously Damages the Engine

The engine’s lubrication system is very similar to the human circulatory system. Just as the human body cannot function without healthy blood, an engine cannot function well without good oil. The performance quality and longevity of an engine largely depend on the quality of the engine oil.

2. Fake ‘Three Filters’ Accelerate Engine Wear

The "Three Filters" has long been an industry term, representing three common automotive parts: the oil filter, fuel filter, and air filter. They are responsible for filtering media in the engine’s intake system, lubrication system, and fuel system, respectively. Fake three-filter products cannot effectively filter impurities in the intake, lubrication, and fuel systems. Some counterfeit products do not filter at all, leading to accelerated engine wear.

3. Fake antifreeze doesn’t prevent freezing and corrodes the engine

In addition to having antifreeze properties, coolant generally also has features such as preventing boiling, corrosion, and scale buildup. However, counterfeit antifreeze is usually mixed with low-boiling-point alcohols. Although these fake products have antifreeze functionality, their boiling points are very low, which can easily cause the radiator to boil over. Additionally, antifreeze mixed with industrial salt or brine can cause severe corrosion to the engine cooling system.

4. Fake brake pads seriously affect driving safety

Brake pads are one of the most critical safety components of a vehicle’s braking system, and the effectiveness of braking is directly related to the quality of the brake pads. In terms of braking distance, counterfeit brake pads will always result in a longer stopping distance compared to genuine ones. Moreover, issues caused by fake brake pads—such as thermal fade after emergency braking, reduced braking force in rainy conditions, accelerated wear on the brake drum due to overly hard friction material, and the risk of the brake pad cracking or falling off during emergency braking—seriously compromise driving safety.

5. Fake brake valves make braking less effective

On vehicles that use air brakes, many valves are used to optimize braking performance. However, counterfeit brake valves may cause the brakes to become less responsive or even fail due to craftsmanship and other quality issues, affecting driving safety.

There are many types of counterfeit parts. Here we have only listed some of the common ones, and we welcome readers to provide additional examples.

● Learn to Distinguish and Avoid Using Counterfeit Parts

The proliferation of counterfeit car parts has caused many inconveniences for users, which is, of course, closely related to user demand. Counterfeit parts are almost everywhere, in all auto parts markets and even car dealerships. Here I have summarized a few ways to avoid the possibility of using fake parts:

1. Never Be Greedy for Cheap Prices - You Get What You Pay For

In the auto parts industry, due to differences in quality, counterfeit products are often several times cheaper than genuine parts. It's good to pay attention to the prices of the parts you commonly use on your vehicle. Nowadays, most genuine parts manufacturers have set retail prices for parts within certain regions, and the prices are often standardized nationwide. This is especially true for mass-consumed products like engine oil.

If you find that the price of a part is significantly lower than the normal price when buying it, you need to be cautious. There is a high likelihood that it is a counterfeit product.

2. Distinguish Genuine and Fake Parts by Senses

Counterfeit parts imitate original factory parts, trying to replicate the labels, packaging, and other details as closely as possible. However, because counterfeit products are inherently low-quality and cheap, they can never perfectly match genuine ones in terms of appearance and feel. This includes aspects like the product packaging and the printed content on the packaging.

3. Fake parts are handled very roughly in terms of details

Counterfeit parts are limited by processing techniques and often look very rough in terms of details. Genuine products usually take into account factors such as environmental protection and harm to the human body, whereas counterfeit products often use inferior materials in production, which can give off a pungent smell. Of course, this method only applies to common counterfeit products. For fake parts that are made with attention to surface details, some professional knowledge is required.

4. It's best to compare with genuine products

Comparing with genuine products is the most effective way to identify fakes. As the saying goes, "it's not that you don't recognize good products, but that you may not be able to compare them." No matter how realistic a counterfeit item is, it can never be made exactly like the genuine product because doing so would increase manufacturing costs, defeating the purpose of making counterfeit parts. If possible, you can compare the parts you buy with the genuine ones, but very few people have the option to do this. Therefore, it is important to remember the characteristics of some commonly used parts of your own car.
