Will Thinner Motor Oils Damage Your Engine?

Can today's engine really last using oils like 0W-20?

What do oil weights mean? What does 5W-30 mean? Do thinner oils get better fuel economy? Do thin oils like 0W-20 protect your engine? I spent some time discussing these questions with Mobil 1 engineers and am excited to share what I learned. There’s an incredible amount of testing and verification that goes into labeling a motor oil’s viscosity rating, which is the single most important factor for how a motor oil will perform in an engine. Motor oil is responsible for protecting your engine, removing contaminants, reducing friction and cooling your engine. Plus, motor oil creates a protective barrier between moving metal parts allowing for your engine’s longevity. In this video we’ll use a 6.2L V8 engine cutaway from the C8 Corvette to better see and understand how oil interacts with automotive engines. #Mobil1Partner

  • Am I the only one who noticed the irony in Liqui Moly sponsoring a video about Mobil1 oils?

  • I realize we're talking about weight in general and not specifically synthetic oils, but synthetics can be very light weight.

    I gave Mobil 1 a try when it first came out in a modified '71 VW I used a bit for TSD rallying and a lot of spirited mountain driving. Add the wide weather range in NY. Zero problems. The car ran a lot better and the engine was cleaner inside. I was sold. If any engine would have an issue with oil weight it would probably be a VW air/oil cooled engine. In older engines there could be problem areas. The tolerances were looser and the gaskets might not take to lighter oil and seep.

    Today's engines are made a lot better and tighter. Granted there have been a few that were/are oil users, others that tend to grenade their valve trains, and quite a few "seepers". The point is it's not the oil but the engine. Use the best oil you can afford. It's cheaper to change the oil than the engine.

  • Should I use what my car manufacturer recommends or?

  • Actually, I’m envious of your knowledge. All I know is, follow the manufacturer’s recommendation, change ir religiously every 5,000 miles regardless for the manufacturer’s recommendations (I live in the desert. High heat, lots of dust.) and in my experience, no problems will occur. I think this is one of the simplest things a vehicle owner can do to extend the life of their ride. It’s cheap insurance. ..... I hear crickets 🦗
