Wrong. 0w-xx is simply the Winter rating (hence kschachn's comment). My 6.4L spec's a 0w-40, my M5 spec'd an LL-01 oil, which could be 5w-30, 0w-40, 5w-40. Same engine also spec'd 10w-60.

OEM's are now spec'ing 0w-20 and 0w-16 (note the lower 2nd number, which is the hot viscosity) because oils with a better Winter rating tend to thicken less as ambient temperature drops, thus improving fuel economy during warm-up, which helps them with CAFE.

Nothing quite so misunderstood as the winter ratings. And people can be so adamant about it, all the while not understanding it at all.

If someone is looking at bearing clearances in relation to the winter rating then that effectively illustrates the misunderstanding.

I was able to find some of the elusive PP 0w40 euro SN Plus on clearance at AZ this weekend.

The price for PP 0w40 SN+ on Amazon
dropped to $57 for 6 qts with free 2-day
shipping on Prime (I paid about $75 for
the same a few weeks ago).

Check around at your auto zone stores. It's been on clearance. I always look at the back and it's usually SN, but I found one AZ that had 6qts SN+ @ $3 a qt! I snagged them obviously!

I would grab some of the older SN formula for my Silverado if I didn't already have such a large stash of oil for it.

The SN+ will go in my TGDI Tucson probably for the coldest months since the PP 0w40 has a 206 VI

$10/qt is kind of expensive wouldn't you think.....I mean what are you getting for double the price?

I paid $3 a qt for the ones I bought.

Keeping an eye out at menards as they regularly have $5 quarts of PP including euro grades.

While not a steal for ILSAC lubes, $5 a qt for euro grades is decent.

The AZ, AA, and NAPAs around me don't
carry the PP 0w40, and Pep Boys just has
the 2 year old SN version.

PPEuro 0w-40 is now SP rated (LSPI protection
same as SN+). On the Shell provided documentation,
SP has different specs and a lower VI than the SN+ numbers did.
