What are the common issues with the Blue Whale 2.0T engine?

[MacBrianna]

The common issue with the Blue Whale engine is that engine noise easily enters the cabin when operating at high RPM ranges. Models equipped with Changan's Blue Whale engine include the Changan CS75 and Changan CS75 Plus. The Blue Whale engine is a self-developed engine series by Changan, not just a single engine model. Taking the 2021 Changan CS75 as an example, it is a compact SUV with body dimensions of 4650mm in length, 1850mm in width, 1715mm in height, a wheelbase of 2700mm, and a trunk capacity of 520L. The 2021 Changan CS75 is powered by a 1.5T turbocharged engine, delivering a maximum horsepower of 178PS, maximum power of 131kW, maximum torque of 265Nm, and is paired with a 6-speed manual transmission.

As a seasoned veteran who has run an auto repair shop for over a decade, I frequently handle Blue Whale 2.0T engine vehicles brought in for maintenance. The most common issue is excessive turbo lag, where the response during starts or acceleration is as slow as a snail crawling, especially in traffic jams where you constantly get cut off. Another prevalent problem is severe carbon buildup, with vehicles used mostly for short trips showing noticeable power loss and soaring fuel consumption. Higher-than-average oil consumption is also not uncommon—some cars need a half-liter top-up after just 10,000 kilometers, accompanied by noisy operation. My personal recommendation to owners is to regularly clean the intake system, use full synthetic oil, and maintain steady driving speeds, which can alleviate many of these issues.

I've been driving a Blue Whale 20T engine car for two years now, and the most frustrating issues are these – it always hesitates when starting, lacks power during acceleration, making traffic jams particularly irritating; carbon buildup forces me to clean it every three months, otherwise fuel consumption can soar above 12 liters; oil consumption is also high, with the dashboard warning light coming on to add oil after just 5000 kilometers since the last maintenance; plus, the engine noise is loud, giving me a headache on the highway; while these minor issues aren't fatal, they collectively affect the daily driving experience. I hope the manufacturer can optimize the design to make the machine more robust.

As a car enthusiast, after in-depth research on the Blue Whale 2.0T engine, I've identified several common issues: slow turbo response which affects driving pleasure, especially noticeable in urban driving; frequent carbon buildup leading to unstable power output, particularly when the AC is on; relatively fast oil consumption, with some owners reporting excessive usage; noise control is also mediocre, not as quiet as competing models; while it offers high power and good value for money, its reliability is compromised. I recommend driving more on highways to clear carbon deposits, using high-quality engine oil, and adjusting driving habits appropriately to enhance durability.
