Który olej wybrać? 504/507 Analiza 30 formulacji C3 #358

This is not a typical oil test. In previous episodes, we analyzed individual oils in viscosity grades like 0W30, 0W20, 5W40 and 5W30. Today we go much bigger. This time, we compare 30 different oils in VW 504.00 / 507.00 specification – mostly ACEA C3 and C2/C3 formulations – aggregated into one comprehensive table. The data comes from: • Polish oil forums • Russian oil forums • German oil forums • Different laboratories • Different methodologies All combined into one structured overview. The goal is not to crown “the best oil in the world.” The goal is to: 1️⃣ Show what the 504/507 market really looks like 2️⃣ Make comparisons easier 3️⃣ Help you choose oil based on your real needs Because oil should match the user – not the logo. What we break down in this episode: Viscosity & Stability Which oils have the highest viscosity index (VI above 190–200)? Who offers the “strongest 30s” close to SAE 40 at 100°C? TBN – Alkaline Reserve Why some oils sit around TBN ~10 while others are closer to ~6. When does higher TBN actually matter? Additive Packages – Three Distinct Schools 🧪 High calcium (classic C3 approach) 🧪 Magnesium-oriented, LSPI-aware formulations 🧪 High boron oils – modern low/mid SAPS balance Plus a look at higher molybdenum concentrations and what that might mean for friction behavior. We also discuss ZDDP levels (Zn/P ranges), certification vs. “meets requirements,” and why approval alone does not automatically mean “best formulation.” Key takeaway: The 504/507 market is highly unified. No revolution. No miracles. But clear chemical philosophies, subtle differences in additive strategy, and different optimization directions: • Stability-focused • LSPI-aware • High TBN reserve • Friction-optimized • Balanced and conservative Now the question is yours: If you had to build your personal Top 5 from these 30 oils — what would it look like and why? Most technical? Most reasonable? Most underrated? Best value for money? Let’s discuss in the comments.
