Viscometric properties for Peak's 5W30 formula are superior to that of Pennzoil conventional. Both 5W30 formulas share a pour point of -39C, but Peak 5W30 has a higher viscosity index and better performance in the NOACK Volatility. From this limited data, I'd say it's a pretty decent oil, and if...
Err...yes, Europeans may have a better sense of style and functionality, but Castrol Edge OW30 (aka German Castrol) is bottled in North America as Castrol Syntec...
When will you guys learn that it's what's on the inside that matters...
Don't worry about that, Castrol may decide to rebadge "the golden child" of the Syntec line in gold Edge bottles for the North American market if their campaign with the 5W30 and 10W30 formulas are successful and, of course, charge you more for it.
Up to this point, it's a boutique oil from a...

That's not a problem. Time based intervals are based on the assumption that the vehicle is operated under "severe" conditions (e.g., extensive idling and especially short trips during which the oil never heats up under open loop operation, resulting in higher fuel dilution. Your situation is not...

Is that a rhetorical question?
Those values you mention are for finished lubes formulated with pour point depressants. In my post to which you're referring, I specifically referred to "base oils," not finished lubricants.

M1 0W40 likely contains more PAO, especially as there is still 25-44% of the finished lube unaccounted for in the MSDS. It is clear...
No need to go with your gut feelings on this one; if the current Syntec material safety data sheets are still applicable, then there's no doubt that the current formulation of GC and Edge 0W30 sold in the EU share identical base oil composition.

Here are some kinematic viscosity values for the oils you're considering, including a couple others for comparison. I've been using an old stash of SH & SJ M1 15W50 in certain applications for years. In your case, either oil would work just fine.
The older formulations of 15W50 (and all others...

From a performance standpoint, there's little difference in the physical properties, and therefore, real world performance between the oils you mention. However, if you want to get your money's worth from Exxon Mobil, the OW20 is a better buy because it costs more for them to produce.
Here's an...
