The TRUTH About 0W 20 vs 5W 30 Oil (50 Engines Tested!)

Do Thin Oils Destroy Engines? Lessons From GM’s Massive Recall

Something most all knew, but many still don't believe.

Update: I am not being partial as I show both sides of the coin with 2 different videos. I personally fall on the side of the first video.

Auto manufacturers don't have owners interests at heart.

Threw a lot of numbers out there, but wish they would have shown the disassembled 50 test engines. Would like to have seen actual wear between the different weight oils.

Lol without watching the video I can tell you that it's full of shit!!

If you truly think thin oil kills an engine that is designed for said thin oil, there are Internal Combustion Engines out there that call for even thinner oils than 0W-20. Looking on Motul's website I have seen 0W-8. I don't know what uses it and I would be a bit concerned myself, but I also know none of my vehicles call for it.

Put simple there is no need to worry about the thin oils if the vehicle doesn't call for it. Better yet there is no reason to worry when the vehicle calls for it either even when trying to compare to GM. If you don't have a GM vehicle, then you are fine.

Ford specifies 5W-30 and 0W-30 for the 2.3L Ecoboost ... why even bring up 0W-20 here? EVERYONE should read the information at https://bobistheoilguy.com/motor-oil-101/. 0W-30 is the way to go in our motors.

The only mechanical part that I can think of that survives on 0W-8 is a water faucet.

Watched some of video and realized that's a subie engine they show pouring the oil into, changing the oil on my wife's outback xt is by far the easiest vehicle to change oil I've ever owned, so that extends my nearly 60 yrs of changing oil . On the Ranger oil changes result in far more cuss words.
As far as oil the subie calls for 0w-20 but I do run 5w-30 in summer months, turbos tend to create faster shearing.

I agree if you live in the northern US... Not so much in the deep south. 5W-30 is better in Dixie.

OW-30 uses a thinner oil base, and adds viscosity modifiers to reach the 30 weight. The viscosity modifier molecules expand when heated up. As the molecules expand they get chopped up into pieces from the heat. Good for northern climates, not so good for southern heat.

Except when you have a 2.3 that goes to the track, there Ford recommends 5w-50 in the owners manual of the Mustang. They also recommend 5w-50 all the time in the 2.3 Ecoboost Mustang when you order the high performance package. They also recommend 5w-50 in place of 5w-20 in the 5.0 when tracked. It's not just Ford that does this, GM and Mopar do too. Some of the European manufacturers of performance vehicles recommend 0w-60 motor oil.

I am retired after a 49 year engineering career. Absolutely ever engineering decision is a compromise. Performance vs Cost vs Schedule vs Reliability vs etc. In the case of motor oil the primary driving compromise is fuel economy verse reliability. The thin oils will provide adequate protection in typical driving conditions but if the expected usage is going to put more stress on the engine they recommend an oil with a higher viscosity for better protection.

Great insight.

Something else that I just remembered to counteract what you're trying to say with this entire thread. Ford actually does recommend 0W-20 for the 2.3 Ecoboost in the Ranger. To be specific it is recommended when operating in extremely cold temperatures. I just don't remember the exact temperature right off, but it is in the Owners Manual.

I don't see a specific reference to 0W-20, but they do cite 2 things.
1. Alternative Engine Oil for Extremely Cold Climates
To improve engine cold start performance, we recommend that you use the following alternative engine oil in extremely cold climates, where the ambient temperature reaches -22.0 °F (-30 °C) or below.
Materials

Name	Specification
Engine Oil - SAE 0W-30	WSS-M2C963-A1

AND
"Note: If you use your vehicle regularly above the altitude of 5,000 ft (1,524 m) and under the temperature of -4.0 °F (-20 °C), it is recommended to use the alternative engine oil."
