The Redline is the higher HTHS oil (3.7 to 3.1) of the two, so if you drive the living snot out of your truck in high temps it might be the better choice.
If you're dealing with starting in extremely cold temps, SS has a better result in the -30C CCS test (~4000cP to 6000 for Redline).
For normal driving with a V8 in CT and typical OCIs, I couldn't say how to pick between the two.
I know that I would go with the SS because it has been tested for LSPI mitigation, but that means nothing to you.
 
They are both top quality oils. Use either one with confidence. After saying that, I'm using Mobil 1 EP 5W-30 in my 5.3 as I can get it a bunch cheaper than either Amsoil or Redline and I have an Amsoil preferred customer account.

On the other hand, going to Walmart and picking up M1 or Castrol 0W-40 is an equivalent choice for about half the price - especially if there is a rebate.

The bottles might not be quite as impressive to your neighbors when they see them on your garage shelf however.
 
OP read tech sheets, if those are you two choices who I am to steer you into something else? Read tech sheets like hths and decide. Redline is pao/ester based, high anti wear additives, high extreme pressure additives, it is an oil built to perform. Some folks might just be concerned with the way oil formulations have went, low calcium, low zddp, manufacturers demanding lower viscosities, etc. Oils that are being built to meet the latest spec gf-6 and going to be pretty similar across brands, group 3 with low additives. I'm not sure I would pay boutique prices for these formulations just because one oil may have extra moly (which is a good thing imo).

If you look at branch chain lubrication features you see oils or additives that can out perform anything. Examples of branch chain polymers would be Vii's and other things such as chlorinated paraffins. In the Rats test Amsoil now tests in between Prolong added to some oils. Now chlorinated paraffins can be down right dangerous to an engine, but no doubt will win a one arm bandit test, unless the other oils also have high branch chain polymerization. So we can assume either the rat's test was way off, or the new Amsoil formula is very high in Vii's. Now, on the horizon there will be self healing Vii's that will be the largest advancement in lubrication since the development of PAG and Esters. But for now the modern Vii's shear down with use and leave an engine vulnerable to wear. Adding more vii's would be a move that a boutique oil company might make, that the established markets would avoid. If that is what is going on and I have no evidence that it has other then the tech sheets and the rat test point to this, then running that for the recommended interval by Amsoil would be irresponsible to your engine.

An argument for Amsoil, imo it seams to do better on wear numbers on uoa. Redline does not produce as good uoa's mainly because the heavy anti wear additives also encourage wear and it also can leach ions through the polarity of the base oil.
 
Neither of those.
For your needs,ST will be fine and you can buy another oil change with your savings.
If it makes you feel special you can just put a Redline or Amsoil sticker on your bumper.
 
Chevy V8? Cheapest synthetic you can find or Supertech. 7500 miles interval. Why spend $10+ a quart when you can spend $2-4? Your 5.3 wont tell a difference. Save your money.
 
Two highly specialised niche products are Amsoil and Redline.

Amsoil Signature Series would be preferable for the hyper miler doing an extended oci. Not to say that Redline can’t. The uoa section has shown Redline doing splendid uoa reports running extended oci.

Redline however is better suited for track day events. Where racing conditions commands higher engine temperatures.
 
It wasn't a trick question. All I asked for was an opinion between the two oils and listed my vehicle and engine option in hopes maybe someone has run these two oils against one another and could offer some insight on which they liked better. As far as putting the effort in to make my own decision. I have read up on both oils throughly and have my own opinion but I figured I would ask the question anyway. One thing that didn't take much effort into figuring out by reading your response is that you are a tool.

Whichever one makes you sleep better at night. We’ve established they’re both overkill for your application and will almost certainly be under-utilized to take any advantage of. So just use whatever makes you comfy. Neither on have a statistical advantage over the other in this specific situation.

What do I think?
1) I think you've not given us nearly enough info to help make a credible decision
2) I think you've not put any effort into making a credible decision
3) I think you've acquiesced to a point where you'd rather someone else decide for you, but you're dead set on a uber-costly syn, all other considerations be darned

- Seriously, if you're planning on doing some very long, extended OCIs, along with monitoring progress with UOAs (watching trends and utilizing macro data as a guide), perhaps even getting some PCs, then I think either will do a decent job.
- If you're just going to run a "normal" OCI, I think you're grossly wasting money, and letting your emotions drive your maintenance program, rather than intellect.

Do as you see fit.

You're welcome in retrospect.



PS - neither of those companies mentioned are pyramid schemes; to imply that is disingenuous. They are legit companies and provide products that satisfy a large customer base. Whereas I see little use for them in many applications, that's not because I think the companies are full of illicit activity or mean-spirited marketing. They are premium products that are often mis-used by the end customer. But that's not the product's fault.


Dnewton dropping truth bombs all the time....yet nobody seems to listen and chooses to toss their $ away. Whatevs
 
I'm not sure if you are planning on running extended OCIs, but for standard OCIs I would recommend the Amsoil OE, given the two choices you asked about. Amsoil OE shows good UOAs in this application. Last case of OE that I purchased was $4.75 a quart (with PC discount), but it looks like the per quart cost for a case of OE went up to $4.98 after the first of the year.

Yes, Supertech Syn is dexos rated oil!


Dexos 1 Gen 2 according to the jug I saw yesterday at Walmart, for the 5W-30 anyway.

Tough one.

If it were me I would find a D1G2 oil and stop.


"renowned pyramid scheme company" ?

Really. Clearly you don't know what you are talking about. Why would anyone believe you?


Easy fix Pablo, explain the multi level marketting scheme that's used to the beginners amongst us... to dispell the myths and lies.



MLM is a legal, functional methodology to sell a product which despite mythology does not extend to infinity. Amsoil's mission is to deliver a good product and make a reasonable profit and have knowledgeable people closer to the customer. No different than Redline or other lubricant company. A pyramid scheme is an illegal activity with only money being passed on and has nothing at all to do with selling a product. For someone to post such a thing goes beyond pure ignorance.


^ Well said Pablo! I knew when I saw Amsoil and Redline in the Subject line, I knew that there would be a lot of Amsoil and Redline bashing. Plus, the OP asked WHICH ONE OF 2 oils would be preferred, and you still get the "Go to Walmart" answers. Nothing against Walmart, I have purchased oil there, Sams Club, etc. ( 12qts M1 5W-30 from SC and 2 jugs M10W-40 from WM in stash now) But the OP asked for opinions on 2 specific oils.
