    There are two main battles about break-in.

    First, is the easy break in. Personally, I don't buy this anymore. But, for the record- here it is anyway.



    The other option- Break it in on the dyno. WITH a wideband and a good tune- not a basemap.
    and that's what i'd recommend, and so does ImportBuilders

    personally, i feel that synthetic oil isn't good for any motors that have already been driven on. use castrol or valvoline 10w-30 and change your oil often. synthetic oil is often to slippery and too thin which can lead to premature engine wear. plus, as brian stated oil pressure may never reach high enough levels so vtec will engage.

    I disagree. Synthetic oils will withstand harsher environments. I run 12.6:1 compression, and Mobil1 10w30 full synthetic oil works great for me. The engine run well, the oil handles the high heat in the head from the compression, and VTEC always engages at the correct point. I tried a non-synthetic oil on a recommendation (Valvoline VR1 Racing 20w50), and I torched one entire quart in 100 miles. The engine ran rough, and the oil couldn't withstand the high stress conditions.

    Synthetic and regular "dino" oil are each appropriate for different applications. Run synthetic if you're using a turbo, have ridiculously high compression, or have an engine that's built significantly beyond stock specs. For all other applications, regular oil works just fine.

    Always use regular oil for engine break-in, and new engine component break-in, like camshafts, rings, etc. The synthetic oil will not allow the new parts to 'wear in' or 'scrub in', so it should NOT be used for break-in processes.

    NOTE: The above break-in procedures were borrowed from the now defunct www.crvtec.com .

    Ageed, I alos run Mobil 1 synthetic and I never have any VTEC problems. The boiling point of synthetic oils is substanialy higher than natural oil so it lubricates the motor better than natural oils at higher temps.

    Just to make a final point 18 months after the start of this topic....

    chet and I are both from a colder climate than lsvtec and calesta. as such, our temps are much different throughout the year. Only you can decide what is best for your motor based on your climate, and your tolerences of your particular build design.
