We Tested 5W 30 vs 5W 40 Over Thousands of Miles — One Clear Winner

Choosing engine oil seems simple… until you realize one small decision can affect engine wear, fuel economy, cold starts, and long-term reliability. 5W-30 and 5W-40 are two of the most commonly debated oil grades. Both are recommended. Both are widely used. But they do very different things inside your engine. In this video, we compare 5W-30 vs 5W-40 over thousands of miles to see how each oil performs under real driving conditions. No theory. No marketing claims. Just practical results. You’ll learn: • How viscosity actually affects engine protection • Which oil handles heat better • The impact on fuel economy • Cold start behavior differences • Engine noise & smoothness • Wear protection under stress • Why manufacturers choose specific grades • When thicker oil helps — and when it hurts • The biggest mistake drivers make when switching oil Many drivers assume thicker oil means better protection. That assumption can sometimes cost you an engine. By the end of this video, one thing becomes very clear. And it’s probably not what most people expect. 5W30 vs 5W40,engine oil comparison,best engine oil viscosity,5W30 or 5W40,oil viscosity explained,engine wear protection,car maintenance tips,synthetic oil comparison,mechanic oil advice 📧 Business inquiries & contact: dyka21129@gmail.com
