Let's put an end to this misunderstanding now. Let's take a look at the differences between 5w40 and 10w40 motor oils in this article. Most Ford engines require a 5w30 or 0w30 motor oil, according to the owner's manual for the 2020 model year. And a 0w20 or 5w30 motor oil is recommended in the owner's manual of a 2020 Chevrolet As newer engines are built smaller and running hotter, a thinner weight oil such as 0W provides protection to critical engine parts, while also providing other benefits such as fuel economy and extreme temperature performance. Learn more about 0W oils and their benefits by reviewing our frequently asked questions. In areas with extreme winters and a generally cold climate, the 0W20 oil is better. In areas with mild winters and hot summers, the 5W30 oil is better. For vehicles used for frequent tows and hauling, the 5W30 oil is better. The explanation is simple and you really don't need to delve any further into the topic. The main difference is that 10W40 oil is thicker than 10W30 oil at higher temperatures. Both have almost the same characteristics - the only difference is the oil viscosity. Sadly, that quick answer probably doesn't make it much easier to understand. You will first need to know what oil viscosity is and what the numbers of both motor oils mean. They gave me a 2018 Dodge Town & Country 3.6L rental until they finish my car. I checked the oil in the Dodge and found that it calls for 5W20 oil. And the manual for the 2018 Dodge says that "Mopar SAE 5W-30 engine oil approved to FCA Material Standard MS-6395 such as Pennzoil, Shell Helix or equivalent may be used when SAE 5W-20 engine oil From Mobil website, comparing Mobil 1 0W20 and 5W20: SAE Grade 0W-20 5W20 Viscosity @ 100ÂșC 8.7 8.9 Viscosity @ 40ÂșC 44.8 49.8 Viscosity Index 173 160 HTHS Viscosity 2.7 2.75 Flash Point 224 230 TBN 8.8 NA MRV @ -40Âșc 9200 NA M1 AFE 0W20 is very slightly thinner than 5W20 at operating temperature, but much thinner at start up therefore Working on the engineering or not makes no difference because there is no performance test or evidence. I don't see any engineering from Toyota showing how resilence the engine is using 0w16 vs 0w20. If there is evidence showing 0w16 will last as long at 0w20 with the benefit of improve gas mileage then you have a point. Temperature range comparison Additional Motor Oil References Comparison of the two: Within the engine oil world, viscosity, as the most prominent characteristic, is notated with a term "XW-XX". The digit preceding W describes the oil flow at 0 degree Fahrenheit (-17.8 degree Celsius). W stands for winter. Originally Posted by 1JZ_E46. 0W-30 is about 25-50% PAO base oil, with the remainder being thicker hydrocrack Group III. 5W-30 is all Group III. The PAO is present in the 0W-30 is mainly there so it can pass the "0W" tests, while still meeting all the other requirements of that oil (A3/B4, BMW LL-01, MB 229.5, etc). So Toyota has a specific 0W20 and 0W30 motor oil for the 2020+ Supra. It's labeled as Toyota Gazoo Racing motor oil but I know no car manufacturer makes their own fluids, so trying to figure out who makes it and what it is a rebrand of. Label says it's made in Spain. bobistheoilguy.com. Ten differences between 0w40 and 0w20 engine oils. 1. Top-end oil pressure. 0w20 has a higher top-end oil pressure, which means it will lubricate the engine better at high speeds and RPMs. 0w40 has a lower top-end oil pressure, which gives it the benefit of low-speed protection. 2. Yep, you got me. There are 7 high mileage oils out of 1156 licensed d1G3 oils on GMs list; Castrol and Quaker State each offer a 0w20 and 5w30. This includes duplicates of Castrol's 5w30 and both Quaker States for some reason, doesn't make sense how they'd have two different 5w30 HM offerings. I went to the car parts place to buy the 0w30 which had BMW LL04 on the bottle. However as I had bought the a5/B5 oil in early Dec and I didn't have time off work to do the job till after xmas I can no longer return this oil. So I've been trying to find out the difference between Edge 0w30 and edge 0w30 A5/B5. Thats an older car. I'd use a "High Mileage" oil, 5w30 full synthetic in it. Any brand at walmart really. There isn't much difference in flow between a 5w30 and the Mobil1 AFE 0w30 oil. High Mileage oils keep the seals flexible better so they are less likely to leak. @ECHO Talking . 0w20 versus 5w20 so, you are saying that the vehicle knows the difference between the two at least that is what you implied earlier. Don't have the time or inclination to belabor the point. I'm sure other's here will reply to you 8-) In closing Anyone here say they had a code thrown for using 5w20. No .. I for one have run 5w20 for 16,000 miles and never a .
