@MiltonTheCat - I'm with you on the thinness concerns on 0w-20 versus 5w-30. I just bought a new-to-me 2018 commuter vehicle that calls for 0w-20... but only in the US and Canada. Its manual calls for 5w-30 everywhere else in the world. This, combined with the fact that the vehicle's included oil itself looked... watery and dirty, for oil with less than 500mi on it, has me really concerned that 0w-20 is not what I really want to run in this engine. Manufacturer recommendation or not. Side note - The selling dealer, a branded dealership of the same brand as the vehicle - indicated that they did an oil and filter change before the sale. Shortly after the sale, I did in fact drain out all of the oil, just for the sole purpose of replacing the drain plug with a Fumoto valve. I put all of this original oil back in, as it supposedly had only a few hundred miles on it. (I did see that there was a new-looking OEM brand oil filter installed, in support of the selling dealer's claim of changing it, so I also avoided messing with that for the time being.) As a further aside - I acknowledge my own potential bias against the visually-apparent thinness of 0-weight oil. I'm used to 5W, generally 5W-30 with some 5W-20 vehicles in there. The selling dealer probably used cheap, bulk oil, so who knows if the 0-weight oil will have the same appearance of viscosity (to the eye) as something I buy off-the shelf.

2024-04-08 23:43:53 +0000 UTCTodd, just out of curiosity is this vehicle a GM with AFM? I have an 2015 Yukon XL L83 5.3 on which I just rebuilt the top of the motor at 184k: had 1/2 thou off head for mating, new right exhaust manifold, and new pushrods, lifters (AFM & standard), valve springs, seats, injectors & rail. Even with catch can, oil carbon keeps getting on the valves. From what I've seen you demonstrate, synthetic 5w30 seems resists vaporizing better than 0w20. I'm debating on switching at next change. I live in in central KY, so, no heavy cold winters. Would love to hear your experience with this. Thanks, and Happy Easter to you and your family!

2024-03-31 19:00:35 +0000 UTCThanks for the constructive feedback on the oil reviews. For liability reasons, I avoid providing advice that goes against the manufacturers instructions. With that said, I use 5W-30 in one of my vehicles that calls for 0W-20. The vehicle is no longer under warranty. Best regards, Todd

2024-03-26 00:19:58 +0000 UTCI'm in the market for a new vehicle, but I'm really leery of the 0W20 oil used in new cars. I know the car companies are up against the wall on meeting the CAFE mpg numbers, and the thinner oil increases mileage slightly, which is why they switched. I'm worried that the car companies are quick to trade off engine life, which affects them little, for higher CAFE mpg numbers, which affects them greatly. I, on the other hand, care greatly about engine life and very little about CAFE mpg numbers. I see that you have already done a video comparing the thin motor oils to their thicker predecessors, "Will Thin Motor Oil Cause Engine Damage? Let's Settle This!". The "wear scar" test is of particular interest to me; in the "thin oil" video, the wear scar of the 0w20 oil is about 7% or 8% larger than for the 5W30 oil. However, I believe this is a deceptive measurement, since the wear scar is occurring on a round rod. If instead the weight of the rod before and after was compared, I suspect that the wear difference would be much larger. For example, if you look at time stamp 4:01 in the "thin oil" video, the volume of the wear scar appears to be much larger than 8%, perhaps even as high as 50% more wear. If you have kept any of the wear rods from previous testing, perhaps you could weigh them and see how the volume change tracks wear scar length? The area I live in rarely gets below freezing, and never gets below 15F, so I don't care about the very cold temperature performance. A relative lives in a part of the country with very cold winters; he keeps his vehicles in a garage heated to just above freezing. His neighbors use block heaters. It seems to me that the car manufacturers recommendations for oil weight are of essentially zero value anymore, since they would get into huge trouble if they recommend anything other than the oil weight they used to meet the CAFE numbers they submitted to the EPA. The only argument against using 5W30 in a new vehicle instead of the recommended 0W20 that concerns me is that some people claim that the oil pumps and oil delivery channels are now designed for the thinner oil, and using 5W30 will result in inadequate engine lubrication. I find that hard to believe, especially in light of your observation that the oil pressure gauge (timestamp 9:10 in the "thin oil" video) is half the value, 0W20 versus 5W30. If I use 5W30 and the oil pump fails prematurely, that seems like a good tradeoff for longer engine life. I'm not sure where I am headed with this; I can't at the moment think of any testing that could help resolve the issue. (Maybe run a new vehicle with both the recommended 0W20 and 5W30 and compare the oil flow rate to the engine?) But I do think you should use wear volume (weight of lost material) for the "wear scar" testing in the future, as using the wear scar length minimizes the difference because of the round shape of the rod used.
