【逆効果】白煙対策で「硬いオイル」は罠！過走行車のエンジンを壊すNGな選び方

Is the online rumor that "just put in a thicker oil" to combat white smoke and oil consumption in high-mileage vehicles true? This video uses a Subaru Sambar with over 200,000 km on the odometer as a real-world example to physically compare and verify the viscosity of 0W-20 and 10W-60 engine oils. We explain the risk of damaging a weakened oil pump by simply increasing the oil viscosity, and a professional presents the correct way to choose the right viscosity to protect your car for a long time. "If there's white smoke, just put in a thicker oil and it will fill the gap." This is a common symptomatic treatment in the DIY and maintenance community, but there's a big pitfall here. In the video, we visually demonstrate the difference between the watery, runny consistency of 0W-20 (suitable for the latest eco-cars) and the heavy, stifling resistance of 10W-60 by mixing them in a jug with a screwdriver. The engine's internal oil pump, the heart of the engine, is subjected to extreme stress when cold (when the engine is cold). This article explains the physical structure of the engine, particularly in light vehicles and high-mileage cars, where simply using thick, low-quality oil can lead to pump damage and oil film breakdown due to poor circulation, ultimately shortening the engine's lifespan. [Professional's Note] If you absolutely must increase the oil viscosity (thickness) to combat white smoke, it's essential to choose a high-quality oil with excellent "low-temperature fluidity (base oil quality)" in addition to its thickness. Furthermore, for cars using thicker oil, "warming up" before driving is absolutely crucial. Remember that thicker oil is merely a symptomatic treatment to alleviate the problem; take care of your car by changing the oil more frequently than before. ▼ Time Chapters 0:00 It's dangerous to simply increase viscosity to combat white smoke 0:45 A Subaru Sambar that has driven 200,000 km comes into the shop 1:53 Black sludge from poor maintenance visible deep inside the filler neck 3:17 The physical mechanism of engine oil circulation 4:50 [Demonstration] Visual comparison of the viscosity of 0W-20 and 10W-60 oils 6:12 Why thick oil when cold can damage the oil pump 7:21 Pour slowly with care for your beloved car 9:18 Engine start test and change in white smoke after adding high-viscosity oil 11:00 The reality is that it's impossible to completely eliminate white smoke 11:42 A recommended oil for engines that are worn out from high mileage (Wagner MC Oil) Should you repair your car, buy a new one, or give up on it?
