Obsolete 10W30

If your engine needs a thicker oil at operating temp, then sure.

There have been several threads over the past few months concerning the 10w30 grade.
For most uses in most areas, 5w30 is probably a better oil since it does typically offer better cold specs and can of course be used year round.
10W-30 is fine for those areas that almost never see temperatures much below freezing and is fine for the warmer months everywhere else, although 10w30 was once considered and used as an all climate grade as well.
One of the nice things about 10w30 is that when you're shopping steals on closeout oil, it's almost always the last oil on the shelf, remaining available after all of the 5W-20 and 5w30 have been snapped up.
At the right price, I still buy this grade to use during the warmer months, although I'd select 5w30 were it available at the same price.

Yes, it is. It's almost never specified, at least in gassers, and just about any vehicle calling for an ILSAC rated 10w30 is perfectly capable of running on an ILSAC rated 5w30 or 0w-30.

But, that doesn't mean it's useless or that no one ever would or should use it. If there were a big special and they were out of 5w30, I'd not be averse to grabbing some 10w30. But, I'd rather run the 5w30 year round as opposed to doing a seasonal switch.

Obsolete doesn't mean useless or harmful. I still use my typewriter. I'd be hard pressed to argue against its obsolescence, though. 10w30 works quite well in fairly cold weather, too. There are just better options for the same price.

That idea obviously works for me.

For sure, I think 10w30 might be obsolete in New England, the Midwest, and Canada. However it is quite nice in areas like south Florida, Texas, Arizona, Nevada, SoCal - especially in the summer when a 'cold start' might mean a starting oil temp of 100°F or higher.

10W-30 still should be in usage spec at -5 F.

This still covers a large part of the country even in the winter.

But SAE 30 would also work for a large portion of the continent during a large portion of the year. I don't see people rushing to its defence.

Most of them don't list it anymore.


Perhaps in NA, but elsewhere it's still widely recommended as is 10w40 and 20w50.

If Delvac 1630's smallest container wasn't 55gal, It would probably be in my shed at some stage, and my cars.

Thank goodness for small favors, eh?

This thread has become borderline troll-bait. *eyeroll*

Isn't it ironic that up here in Canada, I can get a Delvac monograde in a sensible container size, yet in Australia, you cannot. It's readily available in a box of four 4L jugs and 20L pails, along with the giant drum.

I'm going to buy a pail each of Delvac SAE 30 and Delvac Elite 222 0w30 and switch the contents and ship the monograde off to Caterham.

X100 ^^^^^^^^^^^^^

I'll use the cheap 10-30 Ultra I picked up on clearance in either the K24 Honda, Prius or Tahoe in the spring oil change

I'm using SAE30 daily. It was -2 F the other night coming home from work and the car started just fine.

You don't mean straight 30wt? That would be honey thick at -2.

If you need better cold start-up flow, then yes, 10w30 is obsolete, IMO.


Better than what? If you need better cold start flow than 10w40 then 10w30 is right back in the thick of things. It's all relative.

Castrol doesn't seem to think 10w30 is obsolete. Their brand new gold bottle Extended Performance offers an impressive 10w30.

Castrol Extended Performance pds


What is impressive about it?


Yes please do explain what is so impressive?

Nah, troll-bait is a "what if I run 10w30 when my engine calls for 5w30?" thread.

I have been saying for years that 10w30 is obsolete because there is no need to use 10w30 in a vehicle when 5w30 does everything it can do PLUS has the added benefit of quicker flow on startup (even when it's 80F outside it will still flow slightly better) The NOACK value honestly means virtually nothing to me, because in the real world there are tons of vehicles out there that have been running 5w30 since new and now have 200,000 miles or more on them. So what benefit would those vehicles have had if they had run 10w30? In my opinion, none.

Yup, as much as we here on BITOG get excited about super low Noack, no car manufacturer that I know of calls for Noack of 4.7%.

Yes I do. Though, I have topped off with some 10w-40 last month.
