Скачать или смотреть The Most Expensive Oil Is NOT the Best: Here's What We Found in Our Tests

We spent 6 months testing 8 synthetic engine oils in real engines under heat, turbo stress, and daily driving conditions. No marketing claims, no paid sponsorships, just oil analysis data, wear metals, viscosity stability, oxidation, and real-world performance.

In this video, we rank the top 8 synthetic motor oils based on iron and copper wear, thermal resistance, oil film strength, TBN retention, and engine cleanliness. Some results completely contradict what oil manufacturers claim on the label, and the oil that finished number one wasn’t the cheapest, but it clearly delivered the best protection.

We tested popular brands like Valvoline, Castrol, Pennzoil, Mobil 1, Royal Purple, Motul, and Amsoil, focusing on turbocharged engines, direct injection motors, and long oil change intervals common in the United States.

If you want to know which synthetic oil actually protects your engine, reduces wear, handles extreme heat, and lasts longer, watch this video until the end.
