    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.
