Street/Track Corvette LS7 - New Motor !

[Smokefan1977]

1st if you look at the hot temp viscosity your looking at 3.8 which is almost a 40weight oil. Both redline 5-30 and M1 0-40 are 3.8.Both M1 and amsoil 5-30's will be thinner then both of these products and not as much of " The Good Stuff ". A heavy 30weight is very suitable for this engine and any LS based engine.

Red Line 5-30 has more then enough ZDDP roughly 1300, but it's also loaded with moly aswell. Oil temps approaching the numbers you posted is extremely high. I usually see about 220 in my LS7. You may consider an aftermarket cooler .

Pablo Im not steering him away from Amsoil. I don't usually mention the product as I don't feel it's better then Redline and for me Redline is less expensive and easier to get. Like I stated my engine alone cost 21k I know what I trust in my mill. Many of my customers are dirt racers and duners I personally don't know anyone that uses Amsoil in their race cars or very expensive toys. If the OP chooses Amsoil then more power to him. Im sure it will work for what he does

?????

Don't think anyone (yet) mentioned Amsoil 5W-30. But if you want a low shear 5W-30 with way more of "The Good Stuff" try this:

Amsoil 5W-30 HD Engine Oil

As you can see, some folks don't exactly know what they are recommending or recommending against - mainly because they are skipping specificity. Many, many people use Amsoil in race engines and very expensive equipment. I have seen it used in gear boxes in jet boats to engines in dirt race trucks.

On a popular Vette forum a lot of people claim there were a few hundred failures because of a bad batch of intake valves.

HDD is a great product. I actually know my amsoil products quite well.....would you like my ZO#????

With his temps I personally would want an Ester based product which HDD is not. You cannot argue Redline would be more shear stable then Amsoil. Although it is a great product for all around use. Please don't get frustrated Amsoil isn't the cureall for everyone. I learned that one myself. I used to be much like you, defensive over every comment against Amsoil and swore it was the greatest thing around.

Do we really need to post the host of Stellar racers that use Redline. Im sure they are some racer everyone has heard of.

Leave it to an Amsoil dealer to muckup a thread. All of the forums I'm on and sponsor on they are all the same. You would gain much more business if you constructed useful post and just asked if they had any product questions to contact you. each and every dealer gets so worked up like slinging oil is their day to day job

 

[Pablo]

Actually HDD has a decent amount of ester and every bit as shear stable as Redline 5W-30. I'm not putting down Redline, just trying to keep the posting factual. I'm not frustrated at all, actually.

 

[Smokefan1977]

Do you know what the % is and Where we can see documentation. I have been told it is Grp 4 only. This came from Dan petersen. Im not sure if he's is still there or not? I talk in great leangth with him at SEME a few years back. Very nice guy and knows his products like no other I have met

 

[Pablo]

Not sure why you insist on taking this thread in this direction. I've done nothing to "muck it up". I stated facts about Amsoil. You made some vague incorrect statements, which I needed to clarify. If you wouldn't have written what you did, (I see you did some edits) I would never have jumped back in.

HDD is not now, nor has never been 100% PAO. It's not possible. I'm sure what Dan told you was marketing speak at the time. Amsoil used to put 100% PAO on their cases until I challenged them, and they quickly stopped. Of course I don't know the exact %, nor does Amsoil publish their exact formula, just like just about all other oil companies. So your asking me for "documentation" is just baiting. HDD is in the realm of 20% or so ester. You do know that Redline is not 100% ester, right?

And actually most racers people "have heard of" run Mobil1. Yeah I know, weird, huh?

At least in my mind.

At the very least choose an oil with an HTHS over 3.6 which the M1 5W30 doesnt. While its apples and oranges my 2011 5.0L Mustang (which specs 2.6 HTHS 5W20) gets 4.6 HTHS 5W40 on the track.

Mobil 1 5W30 = 3.1
Redline 5W20 = 3.3
Redline 5W30 = 3.8
Redline 0W40 = 4.0
Redline 5W40 = 4.6
Redline 10W40 = 4.7
Redline 15W50 = 5.8

PS My personal opinion is the valves should be changed and the guides checked on a routine basis if you are going to continue to track the car.


Thanks for the advise and going forward there will be normal maintenance on the heads. I cant afford to blow up this new engine.

So I take it you like Redline over Amsoil ??

Hey .... thats my question for you smart guys!! Will additional ZDDP help this or any engine that see track duty even if it doesn't specifically address the potential valve/guide issue.

I would say yes in almost all cases. In particular engines with high valve spring force.

I don't think anyone was steering me away from Amsoil. It was recommended for the addtitional ZDDP. I was concerned that it might be too thick for 2 cold starts a day as the car is primarliy my DD. And that it might not be thick enough for track duty. I am definitely looking for more experience advise. Thats why I am asking on this forum.

OK poor word choice on my part.

You are in Calif. I think just about all the synthetic oils mentioned in this thread will have perfectly fine cold flow properties, and even on a cool morning, you probably won't really get on it until the engine is warmed. Also, the amount of zinc or ZDDP has nothing really to do with viscosity, so I am bit confused by your statement.

Okay, thanks. I definitely appreciate the advise from an LS7 owner. I will look at the Redline 5w30. You are saying it is thicker than the Mobil1 5w30 with lots more ZDDP. You are saying that in all respects it is equal to or better than the Mobil1 0w40. Can you tell me that the Moly is a proven motor protector and unique to Redline.

Can you post a link.

The popular Corvette forum that I am on is aware of maybe 30 failures and these were due to EXHAUST valves.

What? Are you implying that Mobil 1 5W-30 was not lubricating properly? Say it ain't so ...

Sorry if I was unclear, I was not saying ZDDP has anything to do with viscosity. And thanks for trying to help me understand this stuff. Yes, I am concerned with cold starts. But if the Mobil1 0w40, Amsoil Z-Rod 10w30 and Redline 5w30 (not sure which would be street/track) all flow as good as the the Mobil1 5w30 then this is a mute point. There are times of the year when temps will get down to mid 40's. And my engine never sees over 3k rpm until at least 150* oil temps.

Actually most people are amazed that I put 87K miles and 30 track days on this motor no mater what oil I used !!!!!

[Dirty_Howie]

Regarding Redline:

On their website I am not finding the ZDDP levels in their oil. Is this not necessary because of their claims regarding the ester based oil. Is it that better in protecting hot motors. Is it true that one of their oils like a 0w40 will be more stable becuase it does not have the package necessary to allow other oils to have this viscosity spread ??

I really am not looking for a war between you Amsoil and Redline guys. But I would like to hear your best arguments for what is best specifically for my street/track LS7 motor.

THANKS !!

DH

 

[JosephHarmon]

ZDDP isn't the answer to all lifes lube ill's. To bad Gm has it in there hands it's likely a failure in the valve train but who knows. To track one of these cars shouldn't void a warranty if used with in the peramiters. It will be interesting to see if they communicate issues. Don't hold your breath.

My car has over 50 dragstrip passes and dozens of all day road course events. I certainly expect it to last a [censored] of a lot longer than 87k miles!

I run Amsoil Dominator series in my two "money" motors. My track oil of choice has also been Dominator.

I've run quite a few LS style motors to the ground and they generally last a VERY long time, a couple hundred thousand miles is routine around here in heavy duty fleet use using whatever synth is on sale!
