Castrol 0w-30 & 0w-40

[Spedestrian]

I just got my order from walmart online and looks like they are shipping the most recent label/formulations. I know @edyvw is a big fan of these 2 oils.

0W40 is API SP. Will see how it does considering drop in PAO base stock.
As for 0W30, absolutely, still has some stash.

Unless you track, 0W30.

Is the 0W30 better than the 5W30/5W40 ?

Is the 0W30 better than the 5W30/5W40 ?

Definiately. Both 0W30 and 0W40 are Castrol's premier products.
5W30/40 are group III oils. They are good oils, but these are step up.

Commonly see the 5w-30 A3/B4 on the shelves but it would be nice to see these grades. Has anyone seen these at the physical store? I suppose one can always order like OP.

Have not seen anything but 5W-30 and 5W-40 in almost 2 years.

0W30 has been gone from AAP and AZ fir some 6-8yrs. 0W40 couple of years.

Do you have a walmart link for the 0w30? I cant find it on their site, what was the price?

Grades falling out of popularity I'd imagine (low sales). Mobil getting the shelving space for their 0w-40 & 0w-30.

Do you work for Castrol?

What quantitative reason would there be to use the 30-grade over the cheaper and easier to find 40-grade from Walmart? Same minimum HT/HS.

Would SN version of 0w40 be better?

I’ve never seen them in person at walmart but I have at some of the autoparts stores. Usually the autoparts stores have old stock 2+ years old.

Thanks, that is all I found too. I get the 0w30 from Amazon for $50 for 6 1 qt bottles.

Not sure. SN was really stout. Will see how SP does.

It is more shear stable. SP 0W40 is around 25% PAO, 0W30 is 50%. 0W40 KV100 is 13.5 and HTHS is probably up to 3.7cP. 0W30 KV100 on paper is 12.1, but VOA is showing 11.6. HTHS is 3.54cP . That is very good HTHS for KV100. Noack is also lower, 8.1%.

Question is, what’s the new new formula look like. Pour point up to -45 C. VI 197.

0W30? The US is still -60 or 57, cannot remember exactly.
