    Break-in oils

    Is there anything "magic" about engine break-in oil? I know you're not supposed to use synthetic oil (though OEMs ship new cars with Mobil 1) and flat tappet cam engines need ZDDP oils. But for a roller cam engine what should I be using? I was always told to use straight 30W mineral oil for break-in. Seems like there is no 30W oil in the stores anymore.

    I see Total Seal 5W30 break-in oil at $13.97 a quart, Royal Purple 10W30 break-in oil at $8.97 a quart, COMP 10W30 break in oil for $6.97 a quart., and Lunati 10W30 break-in oil at $4.97 a quart. Surely COMP and Lunati don't make their own oil and I suspect this is all the same stuff, so why should I pay more?

    NAPA has both detergent and non detergent 30w.

    So help me understand....you post a link to Renegade Lubricants, and tell me NAPA sells detergent and non-detergent 30W.

    I searched Napaonline and they don't list Renegade oils (neither does Summit). In fact, I search on "break-in" and find nothing. They have 594 motor oils listed. I understand I want a non-detergent oil but they don't sort on that. If I click on "synthetic - no" I get 3 choices...all Pennzoil multi-viscosity detergent oils. This is why I rarely buy from NAPA. Their website sucks.

    I need to place an order with Summit so I might as well order break-in oil from them to get to the free shipping amount of $99. Back to my original questions above.

    Intended to be two independent answers, when I want 30w non detergent for my lathe or air compressor I go to NAPA. When I want 30w oil for my Farmall A tractor I go to NAPA. If I want a great break in oil I go to a local Renegade Dealer as do my two good friends in automotive machine shop business. Their racing oil has 3000 parts per million ZZP and break in oil is 2300.

    Since I have a roller cam I understand that ZDDP isn't nearly as important. I'll probably buy just one of the listed break-in oils from Summit. I would just like to understand why there is a $9 per quart difference. I'm sure plenty of that is marketing hype.

    On a roller motor I would just buy the oil you intend to run long haul and go. Renegade is about $6 per quart for racing or break in if I recall, but not required in your application.

    Here's what GM says for the ZZ502:

    Start-up and Break-in Procedures

    1. After installing the engine, ensure the crankcase has been filled with 5W30 motor oil (non-synthetic) to the
    recommended oil fill level on the dipstick. Also check and fill as required any other necessary fluids such as
    coolant, power steering fluid, etc.

    The engine should be driven at varying loads and conditions for the first 30 miles or one hour without wideopen throttle (WOT) or sustained high RPM accelerations.

    8. Run five or six medium throttle (50%) accelerations to about 4000 RPM and back to idle (0% throttle) in gear.
    9. Run two or three hard throttle (WOT 100%) accelerations to about 4000 RPM and back to idle (0% throttle) in
    gear.
    10. Change the oil and filter. Replace with 5W30 motor oil (not synthetic) and a PF454 AC Delco oil filter. Inspect
    the oil and the oil filter for any foreign particles to ensure that the engine is functioning properly.
    11. Drive the next 500 miles under normal conditions or 12 to 15 engine hours. Do not run the engine at its maxi-
    mum rated engine speed. Also, do not expose the engine to extended periods of high load.
    12. Change the oil and filter. Again, inspect the oil and oil filter for any foreign particles to ensure that the engine
    is functioning properly.
    13. Do not use synthetic oil for break-in. It would be suitable to use synthetic motor oil after the second recom-
    mended oil change and mileage accumulation. In colder regions, a lower viscosity oil may be required for
    better flow characteristics.

    Can't do that....I plan to run Mobil 1 synthetic. GM says not to use synthetic oil for break-in.

    Yet again you show what a total f-ing asshole you are. You didn't even address my original questions you know-nothing dipshit. You only know how shit was done 50 years ago and it's now long outdated. Go f yourself and don't reply to stuff you obviously know NOTHING about. In fact don't reply to any of my posts from now on ....you're as bad as Toxic Rickie. Anytime you post anything you cause shit, markm ....or is it USA1?
