    Default 357 roller motor break-in oil

    I built a 357 W Roller motor and I'm preparing for the initial break-in of the motor at a dyno facility. I have read a lot about oils and ZDDP for flat tapped cams.
    What is the opinion on Brad Penn SAE 30 break-in oil??

    Please advise.

    Do a search here for your oil you plan on using and see how it stacks up.

    I think your oil ranks as 218 out of 226 oils tested. Pretty much the bottom of the list.

    Thank you both Zap's 85 GT link regarding oils should be must read for everyone who builds motors or a car enthusiast. ashley roachclip,agree my motor is a roller cam block. I've used Valvoline for years too.But now in the position of building $5k+ purpose built motors; the concern about what oil to use takes on a new level of concern. After reading the link you could one oil did fair in the top 5 or 10 depending on the test conducted and that was Amsoil. There is some sobering data regarding zink and zink additives.

    Thank you !

    As long as you use an oil ranked in the Extreme protection range you'd be safe. I just picked one in that range that I could purchase locally and not pay through the nose for something that's too exotic.

    Breakin is pretty much BS with modern ring packages and roller cams. My concern would be that Iíve had more instances of rings not seat properly when using synthetic from day 1. But auto manufacturers do it all the time.....

    If you are using older design ring packages there is something to breakin as many of us know from building stuff ďback in the dayĒ

    The engineering side of this - removing rings and cam breakin as a factor ó is get the best oil you can find.

    You wonít go wrong with several different oils on the list.


    I am starting to lean towards AMS Oil as Iíve had great experiences with it at small scale. their engineering analysis is solid, they arenít just mastering in hype.

    The oil Iíve always traditionally ran in my 1986GT is Mobile conventional either 10W30 or 10W40. The wear resistance test data shows itís acceptable oil. What Iíve liked about it is itís detergent properties and itís resistance to thermal breakdown. It does well in those which is why my car has lasted well with a regular 3000 mile service internal

    I agree; breaking in a roller cam block is really concerned with rings and if the motor runs and as it was purpose built for and intended use. Regarding rings, this is my first go around with Gapless rings. Really intricate technology. Once we finished the cylinder bores we had to ship the rings back to them for the Gapless machine work. I have no idea how they will react on initial Dyno engine run. There will sure to be a few careful pulls before we make any real pulls for Torque and Hp evaluations. Even then, I wont allow high RPM or lengthy pulls on a new motor. Way too many variables to sort out on a new born

    Gapless? Wow. I’ll have to read up on that technology.

    Yup- there is a brand of gapless rings. Want to say they overlap a bit and are thinner? Forget...
