A major petrochemical company has a write-up about how the soot from GDI engines is very different from port injected gas engine soot. The GDI soot is basically like diesel soot. A lot of that abrasive, diesel-like soot endes up in the engine oil and the oil filter can't do anything to prevent it. That soot accelerates timing chain wear and increases the risk of AFM/DFM lifter issues.

@@cantwealljustgetalong2 I think the biggest source of it was the oil industry. They wanted to make more money per unit of engine oil so they expand into synthetic engine oils. How do they get people to pay twice as much for synthetic oil? Tell them they will "save money" by running that oil 2 or 3 times longer. Suddenly companies like Exxon Mobil are saying "good for 10,000+ miles!" on the bottle and people eat it up. The problem is that these newer engines are having issues with the soot and unburned fuel that GDI engines are particularly prone to. Yeah ExxonMobil has proven that their oil can hold up really well in testing where the engine really only sees a highway driving scenario with towing mixed in. But try to go 10,000+ miles with that oil in the vehicle that cold starts, idles for a long time, drives less than a mile, and then gets shut back off until the end of the person's work day. That oil will be loaded with contaminants and the engine will suffer.

Great information here. This is what people need to be aware of when they go for their next car purchase, if they care at all about longevity of their vehicle.
Thanks for the vid. It's so terrible that we consumers have to pay this much attention to these details, just to achieve "normal service" from our engines. New tech isn't always better IMO.
Just started using 5-30 in my 2018 crosstrek….after 36k. Km it as it was using a bit in between changes….4000km. Oil change interval. It’s the only way to prevent fuel dilution is to change the oil often and early.
I have some quick questions for you, my friend. Would adding a thicker oil to a car mess with or destroy the electronic oil pump in the long run? Since the car is not programmed to detect what weight oil is in it and it will have to work harder with a different oil viscosity. Will it affect piston ring sealing capabilities with different oil than required? Just wondering as everybody says you have to stick to the oil the manufacturer recommends on your vehicle and nothing else!
@@repairvehicle The gas dilution from the direct injection in the 5W-30 after 5000 miles would be closer to the original 0W-20 it calls for. Although I think I’ll just start changing the 0W-20 at 3000 miles instead of 5000. I think this would be the better option.
I've been working on cars for over 50 years, and what I was taught from day one was the thicker the oil the better protection for your engine. However today's engines cannot handle the 10w40 oils of yesteryear, but I wonder how well a 0w-20 or a 0w-16 can protect an engine over time.
What are your thoughts about using 0w-30 instead of 0w-20 or 5w-30? I live in Texas with 175,000 miles on a 2017 Chevrolet Silverado1500 6.2L V8. Thank you.
You can use either one, I prefer 5w-30 due to fuel dilution for extract protection when oil is diluted with gasoline , but I would change it 5k miles max or 6 months which ever comes first
I have a 2023 Camry se 2.5. It won't see 1 drop of the facotry 0w-16. I change it with Mobil 1 0w-30. Same flow when cold, just a little thicker when hot
That's correct. But what the first number mean is that in order for the first number to be rated as 0w is that the oil has pass a ccs test at -35C and pass a mrv test at -40C. Both the 0w16 or 0w30 have to pass the same test because the first number is rotational. The first number is the oils ability to ensure it can still rotate with this oil. The second number is the oils viscosity when hot. A 30 is heavier than 16.
@jas4925 both numbers is for oil viscosity, oil viscosity when it’s cold and oil viscosity when oil is hot. Oil needs to flow and provide proper lubrication when cold and when hot.
@repairvehicle I hope you are not saying I disagree. I don't disagree. I understand that, do you? I am aware as to why they are recommending a lighter oil. It's for strictly better fuel economy. I also understand what the Kinetoic viscosity of oil is. They test the oils viscosity at 40c and 100c. You will never see 100c of oil temperature in a normal daily driver. Most of the time the oil temperature is 70C to 80c .Whether it's 0W16 0w20 0w30 5w20 5w30, these are all lower viscosity oils. With the 0w16, which is already so light, there is no safety if a direct injector becomes clogged and stops atominizing the fuel, which is where most of the fuel dilution problem occurs. Then, the oil becomes diluted with the fuel lowering the viscosity the engine wear becomes hi.
