I'm looking for another oil for my pair of Nytros too. Not only does it call for a 0w-30 API SG or higher, but it also says JASO MA or higher. The JASO is for motorcycles with wet clutches, yet the Nytro doesn't have one so that spec confuses me. I was all set to run M1 0w-30 AFE until I...

I may have not been clear, when I said first, second and third I was referring to the dates, not the order of the samples. That would make 0w20 AFE on 7/30/17, 0w40 on 2/1/18, and 0w30 AFE on 9/24/18. For wear I was looking at the 12ppm iron for 0w20 vs the 13ppm iron for the 0w40 with over...

Just thought I'd post the results. First sample was the M1 0w20 AFE, the second sample was the M1 0w40 and the third was M1 0w30 AFE. I did notice about a 1mpg drop going from the 0w20 to the 0w40, but the reduced wear was worth it to me. I tried the 0w30 for curiosity to see how the fuel...

Ohh, this is interesting. I'm using the M1 FS0w-40 in my supercharged truck now even though it calls for 0w-20 dexos1. I did notice a fuel economy drop of 1-2 mpg, but I haven't changed the oil yet so I have no analysis to compare. I'm curious how this new GM spec 0w-40 will do...

To revisit this, I ended up going with M1 0w-40. About the only difference I've noticed is mpg has dropped a good 3 mpg when cold (short 30 min trips) and about 1-2mpg on a good long trip where the oil temp is at 220. Since winter is coming, I'm wondering if I should switch out to a thinner oil...

Think this would be overkill? Mobil 1 5W-50 Value Viscosity, cSt ASTM D445 @ 40ºC 108 @ 100ºC 17.5 Viscosity Index 180 Sulfated Ash, wt% (ASTM D874) 1.3 Phosphorous, wt% (ASTM D4951) 0.1 Flash Point, ºC (ASTM D92) 231 Density @15.6ºC g/ml, (ASTM D4052) 0.85 Total Base Number (ASTM D2896) 11.8...

Can someone explain this to me, why is one classified as a 0w30 and one a 0w40? Am I right to assume the M1 is more consistent based off the higher VI? What other stats should I look at? Castrol 0w30 100c: 12.18 40c: 73.21 VI: 164 HTHS: 3.5 M1 0w40 100c: 12.9 40c: 70.8 VI: 186 HTHS: 3.6

What do people think of amsoil signature in either 0w20, 0w30, or 0w40? For the truetrac diff I'v narrowed it down to either their SVG 75w90 or 75w110 so I wonder if their engine oil is worth it over the M1 0w40?

Mobile vs Mobil, haha yup, autocorrect got me! The supercharger has it's own self contained oil supply, and the manufacturer has nothing to say about what to use in the engine. I installed it myself so I don't have a engine builder to consult. For my understanding, why the recommendation for...

I have a 2015 Silverado with the 6.2. Owner's manual calls for 0w-20. For the first time instead of the truck motors being based off the corvette(or vice versa) the 6.2 in the truck is identical to the long block the C7 corvette. The corvette owners manual says to run 5w-30 for normal use or for...
