Like the title says, Is anyone using the Shell Rotella diesel oil (15w 40) in their high performance gas engines? I think I read in a magazine that it was a better choice than any of the regular oils out there at this time, especially for engines with solid lifters. My buddy recommended it. Just looking for additional input.

Depends on the rating.

Rotella has a new fomulation which reduced the zinc levels.

not any more that they lower metal levels. 20-50 vr-1 racing valvoline is highest phosfurous/zinc, more heavy metal contain than mobil-1. its equal to amsoil but less than 1/2 price. im amsoil dealer costs me 6.25 per quart plus shipping. vr-1 is 3.00 my cost at advanced auto. or if you can get a deal on motorcycle oil thats the way to go motul bike oil is still unregulated by tree huggers at epa and its loaded with heavy metal. i have stavley oil engineers report on all oil. and motul is the best phosfurous/zinc content

I have always used Rotella synthetic. I have had this motor apart and everything has always looked great. I am running a 493 solid cam street/ strip car.

Yes.
I was using the 15w-40 but I had WOT ticking so I dropped to the Rotella 10W-30 deisel and all is clear. (Mine is the older formula)

So is the new formula junk? I'm assuming the last batch I got for my Cummins is likely the new formula. What exactly is the point behind lowering the zinc content? No doubt, some "green" reason.

So, should I use this new formula Shell Rotella in my Road Runner... 440, 11.5 compression, MP solid lifter cam (528 lift I think ), ported heads, MSD, blah, blah, blah. I had been using Royal Purple synthetic, but it is sort of a pain in the butt to get.

Its because of the 'new' 2007 diesel engines (big rigs--Cats and Cummins) and their DPFs (diesel particulate filters). Phosphorus and Zinc contribulte to clogging so they are being reduced.

I have run rotella with no problems but don't like using 15w in the cooler months.

I have been using the Valvoline VR-1 20/50 racing oil in both of my '67 Furys with 318 engines. I called the Valvoline people and was told that this paticular oil would be fine for these engines.

Rotella T + STP for me. Fast ramp solid flat tappet is doing fine so far - about 3000 miles.

What about the Chevron Delo 400? It's the same weight, but is it the same or better than the Rotella? And as far as the weight goes, is there really a big difference in the 10W and 15W?

I was running Rotella, but after they reformulated, I quit. I'm back to running Pennsoil 10w30 with a bottle of ZDDPlus.

If your engine has good oil pressure, running a thicker oil than specified is just going to make more heat and cost you some horsepower.

Chevron Delo 400 LE 15W40 actually has more zinc than Shell Rotella T 15W40. I don't remember exactly, but it's above 1300 ppm zinc. At least 1200 ppm zinc is best for a flat tappet cam. I suppose 1150 ppm zinc (approximate) is OK, such as Shell's Rotella T's, for a stock engine or a mildly built engine. That's up to the individual to decide.

Shell Rotella T 5W40 full synthetic has about 1400 ppm zinc.

Don't worry, oil additive packages haven't changed in the last 6-7 years.

Diesel oil will foam at high RPM.

Call Rotella and ask them if it is suitable for your application.

For the last 30 years all I've used in everything from a brigs and Stratton to my 605 Hemi is shell rotella 15/40 HD diesel oil. Never had an oil related engine failure with it.Dave

Same here. Muscle motors even used Rotella when they dynoed my 526 Hemi.

Yeah, I can vouch for that smell. I used it a couple of times in my '02 CTD. And I will probably use it when I finally fire the motor in the Ramcharger (it has been dormant since 2012 and it does not look to good for 2015). That 440 has a hot Comp hydraulic and I don't need lifter problems.

Last year when we rebuilt my 440, the engine builder recommended it and that is all I have used. Its a driver and so it very rarely seem RPMs over 4,000.

My engine builder recommended it (30 wt.) for cam break-in
and VR-1 10W30 for use after that. This with a 284/.484 hydraulic.
6200 RPMs max.

15 dyno runs later, no blow-by and good looking cam lobes.

Of course, viscosity choice is clearance and oil pressure
dependent.

I am using it with a comp 509 cam and eddy heads with their springs. I do put a bottle of richard petty's STP additive (which had a lot of zinc for an additive) to get 6 qts.. I bought a bunch of bottles of this petty stuff when big lots was clearing it out for $2 a bottle. Whether or not it helps, who knows, but it's been working.

Don't use the CJ rated oils. They are for 07.5 and newer diesels with the particulate filters and have zippo for ZDDP. Use a CI rated if you want to use diesel oil and make sure its not combo'd as CI/CJ.

I didn't really notice it until I relocated the puke tank on my '01 Cummins, but right after an oil change it does have a weird smell. Kind of an acidic smell. It seems to go away after a while...maybe as the oil gets some miles on it.

I always run Rotella in my truck, but I use Valvoline VR1 race oil in my cars.

Don't use the CJ rated oils. They are for 07.5 and newer diesels with the particulate filters and have zippo for ZDDP. Use a CI rated if you want to use diesel oil and make sure its not combo'd as CI/CJ.




I think Rotella and Delo 400 CJ-4s have about 1200-1300 ppm of zinc. I've been running it for years as have many others.

Reviving an old post; what's the attractiveness of the 20W-50 weight of the VR-1 Valvoline. I've had it recommended to me by very experienced Mopar mechanic, and I know a lot of wise Mopar people who like it. I'm just wondering, aside from the Zinc content, what's the advantage of the weight?

Would you recommend that weight in my stroked 360, hydraulic roller cam, Florida temps, no racing, just some occasional heavy footed street driving?

20w50is very old school thinking.

I would not recommend 20w50 for anything other than a very old school, and archaicly, built engine.

Run the thinnest oil that will still give you goo oil pressure. I typically run 10w30, max.

In answer to the "anyone using Rotella diesel oil... ".

Yes. I have run 15W40 in my BB stroker and other classics. It has (still) a decent amount of zinc and viscosity seems about right for 3 season use in a typical performance engine. Originally these engines were designed for 10W30. With bearing clearances opened up a bit typicaly, a little more viscosity helps maintain hot oil pressure... especially on the street in stop and go traffic.

For most engines, agree 20W50 is probably on the heavy side though your engine will tell you what it likes. I look for 20+ psi hot idle on a fresh engine.

I still haven't installed an oil pressure gauge which is crazy I know. It came with an electrical gauge since it was an AHB, but I didn't re-install when crate engine was put in, so I don't know what oil pressure I have currently running Valvoline 10W-30. Again, I know I have GOT TO put an oil pressure gauge back in! I figure my engine is kind of old school, not being high tech tight tolerances modern day engine. Yes, roller cam, but still not the tight tolerances of today's modern built engines, no?

I used diesel oil in my poly 318 to get some zinc in and too cheap for brad penn.

The only reason I went a little off topic is I revived this thread that began 2008, and has not been active in OVER two years. It's nine years old and seemed to have run it's course, and Valvoline VR1 was discussed within the thread.

Being 9 years old I doubt any of the oil formulations mentioned then are still made today.

HDEO oils are now CK-4 lower ash. It's all about emissions and mpg in the trucking world.

These oils also undergo formulation changes that sometimes do NOT result in a designation change--meaning 'we' don't know. I bought over a million gallons of DELO 15w40 and 10w/30 over the years working for Kenworth.

We would be notified of a formulation change so that we could deplete stock prior to arrival of new, but they were always backwards compatible.

Relying on HDEO's for a high zinc content (in a high lift, high spring pressure, flat tappet scenario where hi ZDDP is truly required) may be a dangerous practice. The HDEO industry is changing!

Id run it 10-15 years ago with no additive, now, just any decent oil with a bottle of zinc additive, no issues either way.

And using the composite lifters on most everything im not even sure I need to add anything.

Didnt they pull the zinc do the the emission related parts?

There is still zinc in the diesel oils, but it has been reduced over the years, and it is detrimental to converters. ash was reduced due to the DPF's.

See the HAMB discussion: ZDDP again!

My understanding is that the 800 ppm phosphorus limit is really only applicable for dual-rated (CK-4/SN) 30-grade HDEOs. I've been using Petro Canada Duron SHP 10W-30 which has both API CK-4 & Ford WSS‐M2C171‐F1 but has the same additive package for Duron SHP 15W-40 (API CK-4/SN & Ford WSS‐M2C171‐F1). Shell Rotella T4 now only has diesel ratings (no Ford WSS‐M2C171‐F1 either) and no longer has any S-ratings.

Originally Posted By "Blues4U"
But there are those who do have aggressive aftermarket cams and high pressure springs, or people just want extra assurance, like me. I use a heavy duty diesel engine oil with typical zinc level of >1200 ppm. Sholoff posted some brands a couple of posts up, any of those are good oils. The new CK-4 specification for HDEO's raises the performance level up even higher, but beware of oils that list both API CK-4 & SN service classification, as they now are required to meet the lower zinc levels of the SM category. Stick with an oil that is CK-4 only and you'll be just fine.

I'm NOT a fan of aftermarket oil additives, like ZDDP in a can, as they can (and probably will) upset the balance of the chemistry of the additive package, which includes other surface acting chemicals besides ZDDP, and just mixing the unknown chemicals together with no way to know how they will react is looney, no real chemist worth his diploma would approve.


Originally Posted By "Blues4U"
Also, just to clarify about ZDDP, it is, as I posted above, a surface acting chemical. It has a polar head (seeks to attach itself to metal surfaces) and an oil soluble tail. It reacts chemically with the metal surface due to the heat of operation to form a glass like layer (what we geeks call a "tribo film") on the rubbing surfaces of the engine, to provide a self sacrificing layer. When the parts rub together this layer will rub off, preventing metal to metal contact. As the layer is rubbed off, additional ZDDP in the oil will plate out on the surfaces to replace it. The rate at which the film rubs off is related to the severity of the load (aggressivenes of cam and pressure of the valve springs). A mild or medium severity cam and low to medium pressure springs will remove the film at a lower rate than an aggressive cam with high spring pressures.

Now this is important. The tribo film will only get so thick, no matter how much ZDDP is in the oil. Putting more ZDDP in the oil does will not provide a thicker film. Let that sink in for a moment. More ZDDP does not equal a thicker tribo film. What it means is the oil can protect the surfaces longer than an oil with lower levels of ZDDP. In theory, if you only put a few hundred miles between oil changes, even when using a modern SN gas engine oil with low levels of ZDDP, you will probably never deplete the ZDDP out of the oil and never have a wear problem. Of course, that depends on the aggressiveness of your cam and the pressure of the valve springs, and how hard you drive it.

Rotella? Go to your local Walmart and look at the Diesel oil selection. There are now THREE grades of Rotella. Saying put Rotella in it has little meaning unless you specify the grade.

If you want to KNOW what is in a particular brand of oil for phos and zinc, the best way is to just swing by Walmart and buy a quart and then stop at your local big truck dealer and ask for an oil sample kit at the parts dept. There are a few different labs, Wearchek (sic?) Blackstone and Caterpillar are a few.

Cost, $15-20. Pour some oil in the bottle, fill out the info form and hand it back to the parts guy to send out.

In a week or ten days you will know exactly how many PPM is in that brand of oil.

I see that the phosphorus (antiwear component of ZDDP) level was only 825 ppm in your sample of Delo 15W-40 and that it had the low end of viscosity (12.6 cSt @ 100°C). The viscosity range for 40-grade oils is 12.5 to <16.3 cSt.

Who is the newby here? I guess you're referring to me? Why so critical and picky for crying out loud. If so I joined six years ago. I was asking about VR1 since it was mentioned in thread and thread had died. Thought it was ok and didn't start a new one because so often there are multiple threads covering related information. No, they don't charge for new threads, but man there are a lot of redundant threads. Sorry if I offended....again. I more laid back than the average member here, so it appears.

That was what was in it when I bought it. It has been switched back to Rotella T4 15/40.

The last analysis report for T4 I saw on Bob is the Oilguy showed similar Zinc levels and Phos around 900-1000 ppm IIRC. I don't recall the viscosity but there were no negative comments on it so I assume it is acceptable.

HAMB member Blues4U states that he is a lubrication engineer and his posts confirm that he is quite knowledgeable about engine oils.

One of the points he makes is that modern HDEO is very suitable for flat-tappet gasoline engines and that these oils do not require ZDDP supplements. This is in agreement with GM TechLink's Engine Oil Myths.

The Delo and Rotella appear to be excellent flat-tappet engine lubricants even with the much lower phosphorus concentrations than the 1400+ ppm that many people believe are crucial. I also think that it is not beneficial to use an oil that is thicker than necessary. See Engine Wear.

This is the answer I got from Shell, when I asked about the new formulation. I use it in my older muscle car engines, and recommend it to my customers engines.

Hi Jim,

Our CK-4 formulation still has about 1200 ppm of zinc and 1100 ppm of phosphorus, and should still be able to provide adequate protection for flat tappet engines. I’ve attached a brochure that goes over the chemical changes in detail.

I hope this helps.

Best regards,

Aly
