Why is rotella hated by some?

when was this?

10? Years ago now ~ish. Very early in my career which is why I don’t have great memories of it.

The Bus fleet was significantly more recently. Tear down was Oct, 2019. Arguably, the bus fleet’s fault for trying to extend OCI’s on a fleet oil. But still, premature failures in several ISB engines. (Note, they did not switch off of Rotella. Just went to T5, and reduced their OCI’s.)

im curious, what were the oci's?
 
9000 miles. Which is significant for a vehicle that barely averages 16 miles an hour. Hour wise, it was between 500 and 600 hours on the bus.

They reduced down to 5000 miles / 300 hours.

Thanks. Honestly this is why I do 3-5k mile OCI's. Most of the time its closer to 3k. Most hours Ive pushed on an OCI is 95 hours.

Sure, that’s absolutely safe.

In a fleet world, you have a product like Castrol Vecton that guarantees 900 hours in a garbage truck application, with their long drain 10w30. In writing.

(Note, I have nothing, absolutely nothing to do with castrol products at all. It’s just in their marketing material.)

While, I generally agree with Dnewton that there isn’t a huge statistical difference in oil quality, when run under normal conditions. That wasn’t what was asked in the thread. Nor was my opinion on other oils, which is why I don’t / didn’t bring up any of the other big HDMO brands. (Delvac, Delo, Citgard and Rotella are the top 4 in NA by sales. Not in that order.)

If you’re not pushing an oil in your application, use whatever. I answered the question in the original post, strictly with my opinion. That’s it. As that is all that was asked.

If it was asked of me to bring statistical proof and data of why an oil did XYZ, I would bring forth what data I have for a comparison sake in conversation.

Again, I strictly presented my personal opinion, based on my experience.

Im running Rotella just because the Ford list isnt too plentyful in terms of 5w40. There isnt much to choose from other than T6 and VPB. Though I might go VPB next go around...
 
I like both but prefer the Delo and that's just me personally, I haven't checked pricing but for years the Delo was cheaper from Walmart than the Rotella. I really liked the Delo XLE 10w30 in my Civic's but can't hardly find that anymore and when you do it's not a very good price either.
 
There is nothing wrong with Shell Rotella. Ive used it on mutiple occations. My friend worked as a OTR driver and shop mechanic for a well known nation wide moving company. They ran Rotella mostly and others. As long as you follow the engine manufacturers API or euro ratings you won't have an issue. IMHO as some have said. The more thats sold, the more chance of a gripe here or there. If someone loses an engine, they have to blame someone. My freind lost an engine using rotella on a truck that he bought used. He said when the shop tore it apart some one installed a main bearing cap in the wrong order. They were shocked it did not spin a bearing sooner. Check around and ask some trucking companies what they use. I would estimate 90% do.
 
Hate is a strong word… Dislike? Yes. However…

T2 / Rimula / Triple Protection (national account / fleet oil) and T4 both have notoriously sheared. Particularly bad in stationary gen set applications.

Their marketing is misleading at best.

The product (T4) is over priced. Extremely over priced, because marketing is a hell of a drug.

Their product support group has been outsourced. And at least, in my experiences, they have generally bad product support.

T5 product line is “okay” at best.

T6, while generally overpriced, is a good product that is widely available. And you pay to play on retail shelf space. So I partially understand that.

Industry complaint:

The way they treat their distributors is terrible. And they’re hard to deal with.

Again, I wouldn’t say hate, as that’s too strong. But disliked? Yeah. In the T4 “conventional” and T5 syn blend product space? Better products are available for the same, or less money. Especially if you’re a fleet looking. T6 is a good consumer product choice, that is widely available. (But still over priced, in my humble opinion.)

Pretty much everything here, and I will add other performance problems.

There's a lot of guys in the racing and performance car scene who swear by Rotella. They usually complain of issues down the road, attributing it to anything but the oil, such as premature bearing wear, drops in oil pressure, coked rings, and scuffed piston skirts.

One in particular that stays in mind was a dirt track guy who didn't understand why his oil pressure wouldn't sustain on long runs. He was using T4 15W-40. They put it on an engine dyno (for a different reason) and used a clear dry sump they had in the dyno room. After a few pulls, they noticed a lot of foam in the dry sump. With a light load against it, they got the oil up to 240°F and then held it at 7500 rpm. They held it a little over a minute as oil pressure gradually fell down below 40 psi. They took it back down to idle, let the oil flow settle, and the sump was more foam than oil. The shop had Maxima SAE 50 on hand so they poured it in as a quick fix. Barely any trace of foam and oil pressure held steady at 80 psi through the pulls. He was using Rotella because it had more "zinc" with no consideration for anything else, which is quite common for a lot of people outside of BITOG. Because he'd heard Rotella was so great, he didn't even consider it was the problem.

I've witnessed the same thing in motorcycles. "But it's JASO approved..." I don't care about the (weak) cert. I care about the valvetrain getting noisy after a ride and seeing nothing but foam in the sight hole.

It's very volatile with a Noack of 12% (both T4 and T6). The add pack is as basic and generic as you can get. There is nothing exceptional about the oil and no value for the price point.

I've heard two older guys (one a mechanic and another a OTR trucker) in real life tell me to avoid rotella. I'm a fan of it because its consistently around $22/gallon at walmart. Anyway both of them said it should be avoided, one said its gritty when you rub it on your fingers after an oil change (ive never personally experienced this), Valvoline is better etc.

and then theres some posts on here about avoiding rotella (in any grade)

is there a reason for the rotella hate?

I can understand the hate against boutique oils for the price but ive never heard or read anyone hating valvoline or some of the other brands..
Because it sounds like cheese dip. Too much viscosity and insolubles.
 
My FIL and I were discussing diesel oils this weekend, since my newish car is a diesel and he spent his career driving a big rig. He said he used Rotella up until his last truck, a mid 2000s Peterbilt something or other. He said for whatever reason it burned Rotella, and when he switched to Mobil Delvac it stopped burning oil.
 
The Ford 6.7 Powerstroke guys who get their oil analyzed say that Rotella "shears down" faster than other oils, but if they change it every 7,500 miles it seems to protect well.

Rotella is under 20% of the market share in HDMO. Actually I believe under 15% but I’d have to check the numbers again. The majority of the largest fleets in the U.S. actually run Citgo. 5 out of the top 20. But over all market share, last I checked in order are: Rotella, Delvac, Delo, Citgard, Guardol/DXA, Duron, Vecton - I believe, in that order. P66 and Petro Canada were fighting for 5th place. 8th place I believe is Duramax from Reladyne or Valvoline Premium Blue.

I'd like to hear your opinion on Delvac if you don't mind?
 
1. Yes I have UOA’s. I was involved in a lawsuit over it. I’ve also been involved with many other Rotella shearing issues. I do have some pictures of main bearings from a major bus line that had several Rotella failures. As we went through a tear down there.
What lawsuit? Where was it filed? Was it settled out of court? If not, what was the outcome? I'd like to hear about the results.
Where's the UOA data from the failed bearings, etc?
What other "Rotella shearing issues" are you referring to?
In another post, you answered about the buses also having extended OCIs; is that correct? What data exists to show that other brands (Delo, Delvac, etc) would have not sheared under those same circumstances? What you said was that they shortened the OCIs and then went to T5; is that right? So, how do you know that Delvac or Delo would have not also sheared under those same initial conditions which caused the failure(s)? Were they doing UOAs along the way? How did they end up with so many ruined bus engines? Sounds to me like they were not properly monitoring the UOA data. I'm wondering if these failures were not so much lube related, but a failure to properly monitor extended OCIs?

2. It’s pretty clear to me their marketing is misleading. It might not be to you, but that’s marketing. Everyone sees it differently.
What Rotella marketing claims are specifically "misleading"? If it's clear to you, then by all means, expressly describe it, please. Provide the links to the marketing, and show what it is you find to be misleading. And, then show me how that contrasts to the other brands; which I presume you imply that they are are not misleading. What I'm asking for is for you to be specific about the misleading claims you believe to be falsely represented by Rotella.

3. If you call that market priced, you’re in need of more market pricing research. As, I don’t think it’s anywhere in normal market price vs quality. (Exception being T6.)
If I call "what" market priced? I never gave a dollar value for anything. What I said is that, ignoring regional sales pushes, Rotella falls inline with the other major brands in long term pricing strategy. In any given month, Rotella, Delo, Delvac, VPB, etc all have sales pushes that end up making one brand less expensive than another. What I was referencing is that the major HDEO makers typically compete in the same markets, and so they cannot afford to be unaffordable for long, lest they lose market share.

4. If you think SOPUS has been the same group for decades, then who’s still there in their lubricants department these days? Everyone I know has jumped ship and moved on. I could name names, but I prefer not to Dox people. And it’s also frowned upon on this site.
Employees change jobs due to all manner of reasons. That's not the inference I took from your initial complaint in your previous post. How does SOPUS employee retention relate to consumer loyalty at the shelf at Walmart??? You've lost me here.

5. This is the internet. Welcome to opinions. We all have them. I have my proof, it would require me to opsec myself, and to reveal alot of the inner workings I see in the lubricants business.
You may have the proof, but you haven't posted it here for us to see; you've not backed up your claims. It's easy to stand behind anonymity and make bold claims. I understand that perhaps you don't have the ability to reveal where you work; no one wants you to risk losing employment. But without the data to back you up, it's just hearsay at this point.

6. I’m glad you have 30,000 samples in your database. We do that in a few months between all our oil analysis labs. Whether it’s Predictive, Polaris, what we send to majors, what we send to blenders, etc. Let alone the tens of thousands of retains we have. Both VoA and UoA retains.
Can you share that data? And more importantly, does it show correlation to your claims regarding the claim of Rotella shearing and the failures you reference above?

7. It seems like you’re tainted too, coming out and attacking an opinion. Pretty foul way to converse overall, in my opinion. If you wanted to have a conversation, I could support my opinion. But you don’t, you want to attack and try to flex your 30,000 samples or what not. Congratulations, I’m glad you have those. That’s very good, oil analysis is great. More people should do it.
If I come off "tainted" then I haven't done a good job communicating my interests. I value data-driven investigations and decisions. When people make claims, I want to see the basis for the position. Often things are anecdotal; a sample size of one or a few. That's not enough to convince me of large scale concerns regarding oil shearing, as you imply.

This is strictly my opinion on the product. Which is what OP asked for. Take it for what it’s worth. This is the internet.

Edit: Much to many people’s dismays, I don’t hate SOPUS. The other side of my family is the largest SOPUS joint venture in the U.S. We have also purchased 9? Shell distributors in 20 years.
I think what I object to regarding your position is that you made a lot of large, sweeping accusations with no data presented to back up your claims. That's typical of the internet conversations, for sure. I don't think anyone has any "dismay" about your love or hate for SOPUS; I doubt anyone here is that deeply vested into your opinion as to be dismayed. It's not that your opinions are invalid; it's just that they're unproven to us here at BITOG. What your family does really doesn't interest.

Help me, and others, understand these bus failures; tell us the specifics about the lawsuit and evidence presented therein, relative to Rotella and it's "shearing" and "misleading marketing".

I'm not trying to taunt or troll you; I apologize if it comes off that way. What I want to see is the real data to backup your claims.

Yeah I’m going to need my laptop to reply to this. So might be a bit.

But I’ll get as much info for you that I can legally share.

Just a note, I’m just not a sales rep. I am the owner of the company. One of the largest oil distributors in the U.S. So there are things I can share, there are things I can’t share. There are things under NDA’s. Etc.

I’m not worried about losing my job. But, there’s a lot of eyes out there. And I’d prefer not to have awkward conversations later.

I’ll share what I can. But once again, this is strictly my opinion.
 
I'd like to hear your opinion on Delvac if you don't mind?
https://pqia.org/2018/07/03/7353/

That summarizes my thoughts on Delvac 1300.

Being completely clear here, so I’m not a brand hater. I think I most if not all “conventional” 15w40’s - Delvac 1300, Rotella T4/Rimula, Chevron Ursa/Delo 400 SDE, P66/Kendall Fleet surpreme EC, Citgo Citgard 600… meet spec. That’s all they do. That’s all they’re designed to do. Because these guys and girls go duke it out over pennies for national accounts. While people like me harass them for a higher delivery fee.

I’ve seen DD13 wear scar testing from everyone on that list. And, they’re all not great.

I advise all my customers to step up to a synthetic blend. Whether it’s T5, XLE, Super D-XA, Citgard 700, etc. etc.

I also believe (or heard) Mobil counter shell’s claim and claimed Rotella didn’t meet spec.

The truth is, both will pass the DD13 test, 9 out of 10 times. But that 1 time… will fall just short.

How about T-6 and D1?
 
How about T-6 and D1?

T6, I’ll echo my previous statements. I think it’s fine. I haven’t seen the issues others have with it in this thread. But I don’t pay attention to the motorcycle market at all being honest. I see very little T6 in the heavy duty market place, outside of retail sales. A few smaller fleets here or there will run T6 5w40.

I haven’t seen much Delvac 5w40 in the market place. I can’t think of one fleet off the top of my head in my market region that runs it actively.

I do see a lot of it in back up generators. Like… a lot of it. A number of generator maintenance companies swear by Delvac 5w40.

I can think of a few that do run Mobil Delvac 5w30. One fleet had early problems with it, in pre-emission CAT engines. They were a mixed fleet. Lost all their 2003-2008 CAT c12s. Oil problem? Maybe. This was a few years ago. National tanker fleet.

5w40 is a weird one in my area. Most people skipped over it… we have a few contractors on it… a bit of C1000 and Kendall SHP. But trying to sell fleets $20/gal plus oil is hard. When a syn blend 10w30 can be had for under $15.

When PC11 was under development we helped out Afton with a few million miles of fleet testing / on road testing with 5w40 formulations. So I’m *speculating* that it would be similar formulation to what you see in T6 right now.

I generally like 5w40. It’s just a hard sell price wise for fleets. For consumers, that aren’t trying to do 80,000-120,000 mile drain intervals, again. Not pushing the oil. If you like it, use it. Any brand will be fine.


But I don’t get into the UP of Michigan. We stop about at traverse city. Doesn’t really get cold enough to truly justify a synthetic 5w40 often. At least not consistently that you’ll see in other places.

Edit:

Delo has very little market share in my area. I only run across drums of Delo 5w40. Nothing in bulk really. Maybe a few farms in Michigan. But I can’t really comment on that market much. We mostly play in the Commercial and industrial market. Along with our pcmo business of course. Ag is hard to break into if you’re not a co-op.
