Looking for pros or cons. even suggestions for break in on engine stand. Has a roller cam, so not worried about wiping a lobe.

It is best to put a new engine under a load to help seat the rings, I dont agree with running a engine on a run stand. others will argue.

Ive used it alot BUT I always use a can on comps zinc additive, and dont eat parts.

Our old motors are stone age tech, loose and low rpm compared to most anything modern.


Just add zinc.

If im using a composite or a roller lifter a stand is a waste of time, put it in, dial it in and run it hard.

It just pisses me off when I put it in the car to have a leak that can't be easily repaired. The main reason for engine stand is much easier to fix IF a problem should pop up.
Also, the roller should have no need for the zinc.

Driven BR is what most of the top engine builders use now...engine dyno is better for breaking, or in the car. Engine stand with no load is not good for seating rings.

My 2 cents, Mark

You can look at it this way.. how many guys
put the engine in the car then break in there
flat tappet or hyd cams for 20 to 30 minutes
and they live... but on a roller engine I
set the carb and check timing then hit the
track.. thats my break in and I use what ever
oil I'm going to run(I dont use a break in oil
but I do change it and the filter after the
first weekend

I doubt it matters what you put in there. Rotella or Walmart oil. Most of it comes out of the same tank anyway, just gets put into different bottles. I buy the cheap stuff at Costco when they have a sale.

I have to disagree with you here, AndyF. Although the base construction of the oil is very similar, oil companies have always had their secret recipes of additives and detergents that define them from others. The oils might break down all around the same time, but how they protect your engine is what sets them apart. Besides protecting wear surfaces, they differ in how they hold contaminants in suspension to allow the filter to do its job. How they handle temperature, moisture and bypass gases also comes into play. I'm sure there's more to it than that. I've used all kinds of engine oils in my life. There are some that I will steer clear from, and some that I use religiously, and then there are those in the middle that I use if my choices are limited. But, yes, there are major differences between what comes out of those plastic bottles.

Go for it. T1 straight weight or t4 if you prefer multiple viscosity will be fine. (So will many other oils both cheap and expensive.) I'm assuming you just want to warm it up, heat cycle it a time or three, make sure nothing is leaking, maybe retorque the heads if you want, and so on before installing it. Personally I feel there's nothing wrong with doing this, you're not talking about running it for 4 hours straight with no load. If a couple of heat cycles wrecks your ring seal then I feel it was probably no good in the first place. And let's say you find a leaky freeze plug or something before bolting it in the car...you'll be glad to find it at that point....

I'd just drop it in, if you're not going to dyno it. Unless it's a real pain to take it out, incase you find a leak, or something.

Seat the rings on it, or whatever coventional, but synthetics are worth real power afterwards.

You take any new engine to the race track--it gets faster and faster for first 3-5 runs then ...you know rings are done
No way it hurts to run on a stand for a 1/2 hour or so
Street car--take it down the road and let off--accelerate then let off it
The decel helps better than anything to seat rings
With todays modern machine shops and ring packages it is hard to screw that up
I totally agree seat rings with dino oil then later go to synthetic
and...FWIW the zinc / phos additives help All engine parts not just cam lobes

ROYAL PURPLE 10-30 BREAK IN OIL! its not just about the camshaft. it breaks the rings in faster without doing damage in my opinion.

In my opinion Rotella is good enough for what your doing. I once broke in a engine with a flat tappet cam using Rotella, but that was before they reduced some of the additives in it. I normally use Amsoil now, but if i want inexpensive oil i buy Brad Penn. I buy it by the case for $60. Thats $5 a qt. I think its the best inexpensive oil you can buy now days.

I have run Rotella a majority of the time with my 416 Solid Roller. The Rep at Crane Cams that used to post here recommended it for the Crane Roller lifters. That and the 15W40 gives me a good split between oil pressure on the track when the oil isn't hot, and oil pressure on the road when it has been running for 5 hours.

It's all about marketing. Anything you buy is marketed, just like people or things you vote on. We just have different preferences. Trying to figure out what is the truth is impossible.

They changed the formulation on Rotella. I emailed shell and this is the reply I got back. "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."
Could not paste the tech info, but I still use rotella for most older muscle car engines. Main issue with a roller cam is not zinc additive, but bearing clearances and the correct weight oil to make sure you get good flow on cold start up. If you have around .003 bearing clearance use a thick oil like 20-50, if you built with a tight clearance a thinner oil is recommended.

The gibbs break in oil will seat rings faster than anything I've yet seen. A bit pricy, and goes to something like black kerosene after a few pulls on the dyno.

“Oil is all the same”

I hear it all the time........ yet I have seen first hand numerous instances where changing to a different oil has solved a problem.

I don’t bother trying to convince anyone of what they should run for oil anymore....... it’s one of those things you have to experience for yourself before you realize it’s not all the same.

I don’t use oil formulated for low rpm diesel engines, that have really high levels of detergents in a new high performance gasoline build.

On the other hand, I’m a believer of continuing to use products that you’ve had good luck with.
If you’re having good luck with Rotella...... keep using it.

Exactly. Those stupid tribologist just sit around all day playing checkers and drawing a paycheck to run the cost of oil up.




It's no wonder so many guys have issues with ring seal, flag tappet cams and everything else.
