Awesome find? (Edge 0w20 SM)

[dparm]

Was picking up wiper blades for the company vans and noticed they had Castrol Edge 0w20...the old API SM stuff with the 220+ VI. They had several cases worth of it for $6.50/qt.

I grabbed eight bottles to use for my next oil change cocktail.

Is this stuff worth hoarding? Should I go clean them out? Is this stuff really sought after? (should I resell it here?)

It's my understanding this was an absolutely awesome oil. If anyone has the old PDS or specs I would appreciate it. Specifically I want to know the HTHS value (max is 2.6 though I suspect it's going to shear to around 2.4 pretty fast). This is all I could find:

I don't really know how awesome that oil is, but $6.50/qt isn't really a smokin' deal. You didn't say where you saw this sale, but my guess is either AAP, or a mom&pop. I've never seen it at AZ, PB, or OR/Kragen.

AAP had that oil and a D+ filter for $32.99 last month. The filter is normally like $14. If you back out about $5 for the filter, that's under $4.67/qt. Even if you throw that awesome filter in the trash can, that's $5.50/qt.

It was at a local Pep Boys. They had the new SN stuff on one shelf, the SM on another.

Cool! The PB near me just has 5-20, no 0-20 Edge.

You might want to check out the Kmart's in your area.

I picked up 3, One Gallon Jugs of the Castrol Edge, older SM GF-4, Gold Jug, (does not contain titanium and its not the Edge with Syntec). I found this oil at a Kmart between Deland and Orlando off of I-4 for $11 a gallon....SM, GF-4, 5w30.

Kmart is clearing out all the old gallon jugs of synthetic and conventional. They are even including HDEO 15w40 since they are in gallon jugs...maybe by mistake??? At $9 a gallon for Castrol Tection and Valvoline Super Blue....how can you go wrong?

That is a good find. I was stupid and late on the curve to realize how good the SM was and I wanted the SN so I let a lot of chances go by. I have about 8qts. though. Good Find DParm!

If I don't end up blending my own oil early next year at the next change, I'll just bill it to my company and use it in the Odyssey minivans we have.

Good find.

The SM Edge 0W-20 was the lightest oil available on start-up before the SN formulation changed it completely to one of the heaviest (does Castrol really know what they're doing?).

The SM version undoubtedly shears in service like the Toyota 0W-20 does but by how much and more importantly, how much of it's 225 VI it retains as you rack up the miles are unanswered questions since we've never seen a UOA on the stuff.

Nevertheless, if I could find the SM Edge 0W-20 for that price I'd clean them out.

My concern is blending it with other oils. I know it can be done but mixing different formulations is supposedly a "no-no". What about mixing this with something group 4/5 rich? (like Redline, Motul 300V, etc)

As you alluded to before, it could be used to thin-out a heavier oil. I need HTHS 3.5+, per the manufacturer.

Good find, I'd grab it, I won't use the SN formulation. Here's a case where changing specs killed a good product. JMO

As you know all street oils are mixable.
All dino's and GP III's are mixable without issue and that applies to all OTC GP IV's. Mixing with some boutique GP IV/V and GP V oils may require a bit of research just to eliminate any concern.

If you have any concern about mixing the GP III based Edge with something quite different (RL's not an issue) like Motul 300V, would be to ask a hypothetical question.
Ask Motul if you can mix their 300V with one of their own less expensive GP III based oils. From memory Motul does advise which of their oils are mixable. What you're looking for is an technically honest answer not a politically biased one.

Another way to phrase the question is to ask if you need to flush the old oil out before switching to the new. Some engines retain as much as 25% of the old oil in their systems so any change of oil brand is automatically a mix. The answer almost always is that it is not necessary to flush the system as the new oil is "totally" compatable.

 

[dparm]

All of the Motul datasheets say their oils can be mixed with mineral or synthetic oils. The 6100 "technosynthese" all the way up to 300V "racing" make this claim. Even the old "classic" mineral oils say this.

 

[CATERHAM]

Then you're good to go.

An example of modern oils that are not mixable with other oils are the Joe Gibbs XP0 - XP3 and XP6 race oils. But then these are strictly low detergent race oils.

Even RL race oils are completely mixable with their street oils and therefore all other street rated oils.

That's assuming VI is the #1 factor in determining how good an oil is.


As far as mixing, of course you can mix different oils but you don't you think mixing chemistry of multiple oils dilutes and gives you an unknown blend? I don't like to mix oils. It can be done with probably no harm, but it's better to stick with one brand IMO.

I found a bunch of SL 5w30 Royal Purple. Is that worth picking up? It's not discounted.
