Why on Earth do you need a 0W anything ?

Maybe the inconvenient truth is that we all need 0W & 5W oils provided they come with a 16 or 20 after the W.

Hurricane Michael is by all accounts, one of the most powerful storms to hit The US & was powered by unusually high water temperatures in The Gulf. Mercifully the death toll has been low. However with so much extreme weather all around the globe, I wouldn't bet against another even more powerful storm hitting some time soon & next time, you may not be so lucky.

The science says low viscosity oils do reduce fuel consumption. Individuals may justifiably say 'I can't see it!' but across the board, it definitely works. The conspiracy-minded say it's all a gigantic plot by the OEMs & the EPA. That's just plain silly. One of these days the pendulum will swing back and people will, out of self interest, stop wearing their stupidity like it's a badge of honour!

Marco Island is ideal...Easy access to Naples and Miami. I have been to Miami in August...the heat is just awful

I know many "up north" people love Florida. You couldn't drag me there. Too many people. Too expensive. Too hot in the summer. And too cold in the winter. Yep, central Florida, many times, is colder than the coast of SC and GA.

Not this polar bear. There are one million fewer square miles of sea ice in the Arctic than in 1979, that linked story says.

Not everyone can run 48W-784 like you guys in Australia can. We have this nuisance called cold.




Yes, I know it gets cold in Australia also.


I have run 20w-50 in sub zero temps. You let it get good and warm befor you try to drive.

LOL, this has been a great thread, thanks for all the fun replies.

I was talking years ago to Garak I think about the insulation standards in our various countries, and our old house being 4x2 sticks with a sheet of fibro cement either side...nothing between them...compared to Regina...yes ours was woeful, the new place being double brick is amazing in comparison, but still nothing like up North.

We get -7C to 40C (well -11C after the last winter, that set new local records)...I don't feel the cold much, but we don't have "much cold". Very few mornings I can't go outside in track pants and a hoody bare footed.

But the idea of -40C, and thus 0W for environmental necessity is alien to me...15W gets you comfortably anywhere in Oz..
 
But, and again, 0W doesn't "flow to parts" better at 0C than any other W grade...must re-iterate that, as it's popped up in a few posts.

I thought that was the whole idea behind the"winter" number, The pumping ability? Otherwise we could also keep it simple and run straight 30 weight year round.

It's the limits of pumpability at the rated temperature...of COURSE you can't run SAE down to -40...using a logical fallacy that plain doesn't work doesn't make the opposite argument true.


But M1 0W30, 5W30, and 10W30 will all get to the top end at the same rate at 0C.


For whatever reason, people on BITOG assume that a 0W flows, under the direction of a positive displacement pump quicker at all temperatures....and it's not the case.
 
If any of you rust belt cold climate guys ever crawled under a 15 year old car that was driven daily and could not find a speck of rust on anything you might have a conversion. I had to change the 02 sensor in the exhaust manifold of a 15 year old Jeep, cracked it loose with a wrench and it turned out by hand, the gold plating was still on the threads. Almost unbelievable for a guy who lived with the road salt rust in Pa for 48 years.

What drove me to live in such an environment was money. I was rather nice to make, in the early 1980's in Alaska, twice as much per year than the average wage earner does in 2018 here in the Lower 48. I lived in the interior of Alaska for 10 years and never used a "0w" anything. Never had a problem. But then, folks in Alaska tend to be somehow be a little more up to speed on how to deal with cold. We had sump pan warmers, battery blankets, and block heaters. So when we started our vehicles at -50F, they started like a nice spring day. I typically used a 10w30 in my two vehicles in Alaska. Even now, living in Iowa, I have sump heaters installed on my vehicles. When it is going to get down near 20F or lower, they get plugged in. Still use a 10w30 viscosity in everything from my semi truck to the wife's Cadillac CTS to my 2015 Silverado 2500. All my OPE also gets 10w30. Just stuck in a grove I guess. But someone will have a tough time proving to me that I should change things. Haven't lost a motor yet. Oh, the wife's Caddy... a 2006 CTS 3.6 and all it gets is a Pennzoil conventional 10w30. And we are keeping that 12 year old car. Best car I have ever owned.

Yeh, the thin oil people have had to cut down on the clubbing some too. Recent seasons, the ice has apparently been melting before the pups have learned to swim.

Isn't it actually worse 'cos there's more drain back?
