    So far I have driven my truck around 5,000 miles gently, virtually never breaching 3 let alone 4 thousand RPMs. Is there any known benefit to break-in the engine at higher than 500 to 3,000 RPMs? I don't want to push the engine unless there is some benefit to doing so and I figure if there's a good time to do it, it's around the break-in time.

    Thanks

    The book, for my 4cly. Said no hard stops and not towing for 500. I have been taking it easy and am at about 3500 miles. Highest torque on 4cly is at 3800rpm and have driven there (after the 500 miles) on particularly steep roads.

    My theory is if you are trying to take it easy whole new you will not cause any harm or miss any benefit.

    I agree. I usually break in the new engines at max rpms allowed by the ecu.

    ^^ Exactly! I don't know about dyno though but I know they run the motors to circulate the oil.

    Ever watch Muscle Cars show on Spike? Whenever they rebuild a motor, they run them for a few minutes then dyno them at full rpms? Gotta seat the rings!

    I used that break-in method in '04 after upgrading my 88" HD to 95" and it still runs strong and no oil burn. For my new Tacoma though I am taking it easy for the first 1000 miles then I will start driving it "normal" (minus tow). It has 200 miles now and the wife told me I was holding up traffic last weekend :confused:
