We Tested 0W-20, 5W-30 & 5W-40 Engine Oils - Here's the CLEAR WINNER!

Описание: Does your engine oil choice actually matter?

We tested 0W-20, 5W-30, and 5W-40 in the same engine under real-world conditions to find out which viscosity offers the best engine protection and longevity. While most manufacturers recommend ultra-thin 0W-20 oil to meet fuel economy and emissions targets, our data reveals a hidden trade-off.

Through detailed used oil analysis, temperature logging, and wear metal testing, we discovered that the "recommended" oil often runs hotter and breaks down faster than thicker alternatives.

In this video, you’ll see the side-by-side results of how oil viscosity affects film strength, internal friction, and engine wear over a 7,500-mile interval. We break down why 5W-30 is often the "middle ground" preferred by master mechanics and when you should consider switching to 5W-40 for heavy loads or extreme heat.

Stop blindly following the owner’s manual and learn which oil will actually help your engine last 300,000 miles or more.
