Difference in XW-30s #4779720

I recently switched both my vehicles on over to Amsoil 0W-30 and loving it. Both vehicles drive beautifully and its a noticeable difference from what each vehicle specs. Needless to say, won't be going back to the thinner oil.

My question now though, what is the difference between 0W and 5W, besides the cold starts? When I first asked the question here about choosing one oil for both vehicles, someone suggested to stick with 0W for the base stocks and add pack. Guess I want to learn more about this before I make my next oil purchase.

Thank you.

Some 0W20's are thicker at operating temperatures over 5W20's.

The 0w have to meet different pumpability requirements at a lower temp than 5w. To do this without a ton of VII basestocks with better cold flow properties are required.

From a protection standpoint, you’d be hard pressed to find a difference.

In AZ, no difference really between 0 and 5; as you mentioned it is only when cold.

Since you like Amsoil, you could try their excellent SS 10w30....it is super stout and could probably go year round as long as your temps are above 0*F

Why on earth would anyone run a 0w oil if it is above 0* F

Some engines actually call for one. My SRT calls for 0w-40 for example. Not that the Winter rating is overly relevant when it is 15C out like it is presently, but the higher output engines, and many Euro engines, spec a xW-40. GM's new Corvette fill is now 0w-40 as well.

I tried 0w30 in my Escalade and there was zero difference vs 5 & 10w30 in it in SoCal.

Because 2 months later it could be so much colder and they don't fancy changing the oil that often?

One hunch I have is some 0w and 5w oils (eg. from SOPUS) are the same apart from different amounts of PPD in them, as the 40C and 100C KV and other figures are identical apart from the MRV/CCS numbers.

I think the real question is why anyone would 'ever' use the 'water-thin 0w EPA [censored] junk oil' but maybe I'm reading into things too far.

No, you haven't taken it far enough. Are you trying to suggest that the 0W-40 I use in my BMW is "water thin"? If so, you need to learn what the winter ratings mean rather than what you imagine they mean.

You seemed to think a 0W-XX oil was okay here:

I guess my sarcasm was missed by all... sorry. Anytime someone uses 0w-X in anything there's always a person demanding explanation if said user isn't in the arctic circle. It's usually accompanied by the 'water thin' argument. Look at my post history, I'm a fan of 0w's and I even loaded up on the PP 0w-40 that was on clearance at WM recently.
