May 19, 2019 · Answer: If a different viscosity oil is added to the engine other than dexos1™ 0W20 oil, GM recommends that an oil change be performed as soon as practical, but no longer than the next scheduled oil change. in order to return the engine to the original dexos1™ 0W20 oil factory requirements.
Oct 10, 2018 · The better oils will feature some Ester molecules and adhere to metal better for the cold start-up. For summer also the 0w40 is excellent but for winter in Germany 5w30 or 0w30 if the specs show you a viscocity at 0 degrees perhaps close to 50 then you be better than 85. Do not pay attention to the bottle label. Read the specs.
Nov 9, 2022 · Which is better 0W-20 or 5W-20? As 0W20 is a far thinner oil than 5W-20, it is more stable at cold temperature than the latter and flows smoothly through the critical engine parts. 5W-20 is a comparatively thicker viscosity oil and is better for a normal operating temperature range of -22°F to 68°F.
Mobil 1 advanced full synthetic motor oil 5W-30 helps to extend engine life for vehicles of all ages. Mobil 1 advanced synthetic motor oil is designed to deliver outstanding engine protection from the five factors that can damage engines over time and protect critical engine parts for up to 10,000 miles between oil changes. May 1, 2016 · They sell Mobil 1 at Costco as well, but I think it's only in 5w30. I guess I am looking at: -Switch to a 5w30, either dino or synthetic but probably dino -Move to a 0w30, as it will probably also have fairly cold winters -Stick with 0w20, but stay with M1 AFE or move to the EP version, and try to stay with 1 year OCIs (?)
Jun 8, 2023 · 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. Cold weather viscosity. 0w20 has a lower cold weather viscosity, which means it flows easier when the temperatures are colder.
Jan 8, 2007 · At full operating temperature the viscosity difference between the average 20 and 30 wt. oils is nil. At 120 F and below the 20 wt. oils out perform the 30 wt. oils. It takes a good 10 to 15 minutes of driving to get the oil temperature up to 120 F even though your water temperature gets up there in a minute or two.

Nov 16, 2012 · You can also make your own 0W-30 with Mobil 1 oils. Four quarts of 0W-20 plus one quart of 0W-40 makes a very light 30 grade that has better cold pumpability than Mobil 1's 0W-30. Perfect if you WANT a (light) 30 grade oil. Not so much if you need to document the use of a 30 grade oil for warranty purposes.

Aug 17, 2018 · Therefore, 0W-20 cleans better than 5W-20 and leaves less deposits. However, the relative wear performance of 0W-20 vs. 5w-20 is more debatable. It's also one reason why German Castrol and Mobil 1 European Formula are 0W-30 and 0W-40, respectively, instead of 5W-xx -- European engines require better cleaning. See the section under solubility.
