The upper temp ranges for multigrade seem way too low.

An interesting chart, but....

I agree. It seems fairly out of date. If you went by this graph, 5w-20 and 5w30 would only appropriate in the colder parts of Canada for about 4-5 months a year. The rest of North America would be running 15w40 as its lowest safe viscosity.
Note the .au in the link. Those Aussies do like thick oil...
And what exactly is "arctic oil"?

That's incredibly old.
The "Arctic Oil" is very intriguing. Is that Synthetic?

10-30 is only good to 68 deg F!
Thanks! That's a load off of my mind!

Not that old its CI4 SL. Must be for a commercial Diesel operation. Looks OK to me. Manufacturers use too thin oils in N.A. forced in a corner by CAFE and EPA drive cycles.
"Manufacturers use too thin oils in N.A."
That explains the huge expanses of dead cars on the side of the road, with engines completely worn out at only 25~30,000 miles!

All of our fleet have expired at 40-50K recently in the past 10 years. But I drive like an Italian
and dont expect long service on F.E. oil grades; My wife doesnt drive hard though, and her engines are dying too. You have NO data to back up your statement, my personal experience supports my position, as do manufacturer recommended grades outside of North America.

"You have NO data to back up your statement"
Hyundai recommends these oil grades, and warrantys their cars to 100,000 miles, and isn't bankrupt. There's my data!
You have no data to back up your statement. All you have is personal experience which is incredibly vague. If you were really having cars die at 40,000 miles you're so clueless you shouldn't be portraying yourself as an expert in the art/science of automotive maintenance.
FWIW, I had an 01 Accord make 113,000 miles on 5w-20 and I sold it running like new. And I think if you spend some time on this forum that is the norm. If you are having problems with premature wear on your engines, the common factor isn't energy conserving oil. It's the interface between the oil bottle and the fill hole that seems incompentent to me.
