Yep, call me when you are in the -35 to -40 C range. Don’t laugh, that’s Edmonton.
0w30 high mileage availability?

90% plus of the people on here have little or no need for 0w30 oil! Find a 5w30 that's on sale!

When I lived in Toronto I thought that was cold....until one time I went on a winter trip to W Edmonton Mall....
So glad I moved to the tropics.

0w-30s tend to have a slightly lower operating viscosity. I like them for vehicles that call for 0w20 or 5w20 in the US.
One does but all the other ones I know about are ACEA A3/B4 (or similar) with a minimum 3.5 HT/HS. Even Amsoil is above 3.0.

Yes above 3.0, the one is above 3.1. I guess I just think that most of this caters to the European crowd.

Which has the higher viscosity numbers in each pdf, the 0w30 or the 5w30?
You need to look at the HTHS … High Temp High Shear… that’s what the bearings, crankshaft and possibly camshaft see… That HTHS is what really matters the most where the motor oil sees the highest temperature and shear at. The kinematic viscosity is not quite the same measurement as HTHS. I have seen some kinematic viscosity in the mid 11s and the mid 9s and yet both have the HTHS is 3.1 to 3.2.
Most 0w30s I can think of are MB 229.5 approved and Porsche c30 approved. Which like you said those are 3.5 and higher HTHS .
Mobil 1 ESP 0w30
Castrol European Formula 0w30
Redline 0w30
Amsoil 0w30
Here is a curve that contains a 0w30 and a 5w30. Unfortunately it only goes to 0 degrees C . The difference between 0w30 and 5w30 doesn’t get that significant until the temps get way down low such as -35 C .

Actually, you need to look at HTHS. Which has higher HTHS in each pdf I posted?

The 0w30 has slightly lower viscosity. This is consistent with what I said. The graph’s Y-axis scaling is far too coarse. It needs to be closer to 0-100 or 0-50 cST. If 0w20 were plotted on it currently it would also appear to merge with 5w30.

Now look at HPL, Mobil 1 Advanced Fuel Economy, and take a second look at AMSOIL Signature Series…

That was a generalized statement…. I should have made that obvious there.
HTHS is what matters at times.
And like K said there are oils out there with different results..
And I could post that Mobil 1 ESP is 3.5 HTHS … There’s a reason for that being the case. It has MB and Porsche c30 approvals.
Nothing wrong with Amsoil 0w30 or HPL… They are great oils.
Remember though the additive package in HPL is a whole lot different than other oils.

I can't find the HTHS of Mobil 1 0w30 as well as the TBN.
