Jan 18, 2019 · It's not very shear stable though, by design as the HT/HS is only 3.0. Per XOM it is of the GM 4178M level of quality. If I lived in an area with extremely cold winter temps, AFE 0w20/30 would be my choice. These oils from what I understand also have slightly better friction modification than the other M1 oils. Oct 19, 2010 · Since the 0w20 is thinner to begin with, along with having a higher viscosity index, the spread between it and the 0w30 will only increase as the temperature goes down. Mobil also lists MRV specs, which represent pumpability at cold temperatures (lower numbers are better). At -40C, the 0w30 has an MRV figure about 70% higher than the 0w20. Aug 20, 2022 · But the dealership might use B71 2010 0W20 for all I know. A 0W20 could in theory be very similar to a 0W30 - say if you have a "thin" 0W30 vs a "thick" 0W20. The Total 2010 will in theory give you the same as the Total 2312 AND 4,3'ish % better fuel economy under ideal conditions. May 31, 2012 · If Titanium is as marketed as ‘better than’ Syntec, why are A3/B3 oil grades 0w-30 & 5w-40, which meet Daimler 229.5 & 229.3, etc. not offered here in the U.S. as a Edge Titanium? Syntec meets a higher-(more difficult) spec but Titanium in marketing is referred to as ….’most advanced oil’, but it does not meet the most advanced spec’s? 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 (?) Feb 27, 2021 · Due to tightened fuel economy mandates in US Toyota recommends use of 0w-16 and 0w-20. For example in Australia fuel efficiency standards have not been implemented yet and Toyota recommends oil grades 0W-20, 5W-20, 5W-30 and 10W-30. If I had late model Toyota 1.8 or 2.0 my preferred grade would be 5W-30 or 10W-30. .
