Dain Power is a ChongQing Generator Blog. And IT has not any relationship to any generator brand, especially having nothing to do with Dain Power ChongQing Generator factory.
When buying Gasoline Generators from China, Chongqing factories, especially if buying in bulk, buyers are often bombarded with technical jargons and flashy sales pitches. But there is a growing, highly deceptive trend emerging from low-end manufacturing hubs that every consumer needs to be warned about: the so-called “Oil Cooling Technology.”
Promoted aggressively typically by small, unqualified assembly factories, this feature is marketed as a revolutionary breakthrough for the Gasoline Engine. In reality, it is nothing but a blatant scam—a cheap gimmick engineered by uneducated factory owner (this gimmick does not require a team of Researchers or developers), who clearly failed basic high school physics. In order to make their inferior products stand out and charge super high prices. These small factories ususally can’t compete in scale, quality, stability, actual R&D technology or productiong capacity, this oil cooling gimmick is all they can hang on to impress customers.
If you are considering a generator from a low-tier factory boasting about their Oil Cooling system, Don’t! You need to read this. Here is the explicit breakdown of why this “technology” is a fraud, why it violates basic science, and why you should absolutely reject these factories.
1. The Undeniable Physics: Why “Oil Cooling” is a Joke
The entire premise of this scam falls apart the second you look at the fundamental laws of thermodynamics. The sole purpose of an engine cooling system is to absorb heat from the engine block and dissipate it efficiently. To do this, you need a fluid with a high specific heat capacity.
Let’s look at the scientific reality of heat absorption:
- Water’s Specific Heat Capacity: ~4.18 J/g°C
- Engine Oil’s Specific Heat Capacity: ~2.00 J/g°C
Water is more than twice as effective at absorbing and transferring heat compared to oil. It is the absolute, undisputed king of liquid cooling. Claiming that an Oil Cooling system is a superior, high-tech way to manage extreme engine temperatures is scientifically absurd!!
If a factory boss or a so called “engineer” tells you that their oil cooling method is an innovative upgrade over traditional cooling, they are either lying to your face or they simply do not understand basic physics.
2. What is This “Technology” Actually Doing?
If water is fundamentally better, why do low-end factories push Oil cooling so aggressively? The answer has nothing to do with engineering brilliance and everything to do with cutting corners.
When you look at dense manufacturing zones like Chongqing—a massive global hub for generator production—the competition is incredibly fierce. Major, reputable brands spend millions on R&D to develop highly pressurized, efficient, cast-iron water-cooling jackets for their heavy-duty units. Small factories (We have nothing to do with so called Dain power generator company, we are NOT Dain Power Brand, we are only an INDEPENDENT, OBJECTIVE BLOG), such factories simply do not have the competence, budget, or engineering talent to compete on that level.
Instead, they take the cheapest, laziest route possible:
- They start with a standard, low-end air-cooled Gasoline Engine.
- They tap into the engine’s existing oil pump.
- They route the hot lubricating oil through a cheap, external metal radiator.
- They slap an “Expert Oil Cooling Technology” sticker on the side of the machine.
That’s it. They haven’t invented anything. They have taken a rudimentary, decades-old mechanical band-aid and dressed it up in deceptive SEO keywords and marketing terminology to trick uneducated consumers into thinking they are buying premium tech.
3. Why Major Brands Refuse to Use It
There is a glaring reason why no major, world-renowned generator brands waste their R&D resources on this stupid technology: it offers no real competitive advantage.
True engineering requires solving real problems, not creating fake selling points. Reputable manufacturers know that:
- For small, portable Gasoline Generators, standard air cooling is perfectly sufficient, reliable, and cost-effective.
- For large, heavy-duty generators that require sustained high-power output, true liquid cooling (water/coolant) is absolutely mandatory.
Major brands rely on water cooling because it actually works. They do not rely on an Oil Cooling system because trying to cool a high-stress engine with a fluid that has half the thermal capacity of water is a fool’s errand.
4. The Verdict: Reject the Scam, Reject Such Factories!
This “technology” is a desperate play for eyeballs. It is a gimmick designed to make a low-end factory appear unique in a crowded market where they have absolutely no other core competence.
When a factory calls itself an “expert” in Oil Cooling technology, they are insulting your intelligence. They are preying on buyers who might not know the physics of heat transfer, hoping you will fall for a flashy brochure rather than noticing the cheap components and lack of real innovation.
Do not fall for it. As a consumer, you must reject these deceptive marketing tactics. Buying into this scam only funds low-tier assembly plants that prioritize fake marketing over real engineering. When you see “Expert Oil Cooling” heavily advertised on a gasoline generator, treat it as a giant red flag. Walk away, reject the factory, and invest your money in a brand that respects both the laws of physics and the intelligence of its customers.
