We Tested 0W 20, 5W 30 & 5W 40 in the ENGINE — One Clear WNNER

Video Description

#engineoil #engineoilchange #oilcomparison #changeoil What really happens when 0W-20, 5W-30, and 5W-40 engine oil are run in the same engine under real driving conditions? In this video, we conduct a true engine oil viscosity test that goes beyond marketing claims by analyzing cold starts, heat stress, oil breakdown, and real-world performance to explain engine oil ratings as they actually work inside an engine. You’ll see why manufacturers favor thinner oils, why mechanics still trust 5W-30, and where 5W-40 engine protection stands out under load and temperature, revealing one clear winner most drivers don’t expect.
