Вязкость масла - почему это самое важное? Масляный клин и давление масла в двигателе!

This episode is about viscosity! We'll delve into this issue... Oil viscosity is the most important thing! More precisely, it's one of the most important parameters the designer considered when designing an engine. So why shouldn't you change oil viscosity yourself? Because engine oil pressure depends on this parameter! And what awaits those who decide to do so?! Oil viscosity is the most important thing! There are two camps...some argue that it's better to use a thicker oil because it provides better protection, while others believe it's better to follow the manufacturer's recommendations! Some highly respected bloggers claim that boundary friction doesn't exist in an engine, and that it only operates due to the presence of an oil wedge...but this is a misconception! So which oil is better?! 0w20 or 5w40... or maybe 0w16... 0w8!? Why is engine oil pressure needed and why is it important? Why do respected bloggers get it so wrong? If you open a valve cover, what do you see? Why is the viscosity rating so important for a turbo? Why can't viscosity be increased after 100,000 km? Why are modern oils so closely linked to ACEA approvals, manufacturer approvals, and viscosity? A prime example of this is 0w20 C5 oil, with a 508/509 approval, which, by the way, is used by most Chinese automakers. How to choose the right oil? The long-forgotten, and unfairly "forgotten" EXPERIMENTS column will answer these questions and the main question of the episode with numbers. This episode even includes a small contest... I blurted it out in a fit of generosity. Well, since I blurted it out, there's a prize! For those who find it convenient - timestamps: 00:00 - Introduction. 01:53 - Viscosity Experiment (0w20). 05:13 - Why is oil pressure important in an engine, and why is it important? 06:59 - Why is viscosity important for a turbocharger? 09:45 - What if you change the viscosity YOURSELF? 12:00 - Viscosity Experiment (5w40). 14:14 - What can we PRAISE MARKETERS FOR? 17:00 - How long does 0w20 oil last? 20:22 - Viscosity Experiment (10w60) 21:37 - Competition! 23:11 - In Summary... Which oil is best!?
