    Default Delo 400 Testimony - Pajero

    After my Pajero Rebuild I decided to document the use of Delo 400 in a brand new engine. My jetta testimony is here - but used in an older engine.

    As mentioned in my build thread the lifters are absolutely silent.

    I used delo 400 to break in the engine.

    This is just over a thousand km's after the first start



    2009-Nov-21 This is after today's oil change at

    259009km



    2010-Feb-02 259780km - Lifters are still quiet. No smoking and no oil used so far




    I will keep this thread updated.

    NOTE: I am aware that this is not the mitsu recommended oil. This is just a feedback thread on my findings by using an oil I personally prefer.

    259'333km ( 324 km after last oil change ) - I have done a trail in this time as well

    Lifters are still quiet and no oil usage at all since the rebuild

    I fully agree with your decision to use a very good oil but in my experience it does hamper the break in to use it from first start. Problem with this kind of oil is that it lubricates too good and the mating surfaces do not seat in properly so you might have an engine with 10k on the clock but it has not been broken in properly.
    lifters can be quieten down by adding half a liter more than recommended

    hbannink - I agree with your view. Earlier engine / vehicle suppliers used to use special "running in" oils with special instructions to "take it real slow, no revving etc". Some specialist engine builders such as Keith Black etc still do so today. Almost all of today's engines though use the correct spec oil off the shop floor.

    In fact, most of them have already had a run on a dyno at the factory somewhere, and then probably another run through hell when driven by some maniac from the plant to the holding yards before being supplied to a stealer - with a pristine "0" km's on the clock, of course.

    The following rule-of-thumb has proven itself over and over - For a BRAND NEW vehicle - take it slow for the first 1000km's or so to settle the gearbox, diff, camshafts and all other sliding goodies on the vehicle. Thereafter drive it as you plan to drive it once run-in.

    OVERHAULED ENGINE - a few acceleration runs from a low engine speed, under load, will do the initial seating on the rings, Thereafter - give it gas and drive it as a fully run-in vehicle.

    As 4ePikanini has used Delo400 - it will of course do the job but as you said, he can expect a longer wear-in period for the rings due to the friction modifiers. I'd guess the job should be done around the 10 to 15 000km mark.....

    The fact that his engine does not use any oil at all does not imply that it's run-in. It merely indicates that a premium job was done with the boring / honing / ring gap alignment during preparation and assembly..

    Please guys. I do not wish to offend anyone but let's not discuss these issues here.

    I am ( and was before ) aware of these recommended break-ins etc.

    I am willing to possibly sacrifice an engine in the name of research and info ( not theory and speculation ).

    This is a feedback on research thread. Let's wait 200k and then we can either say that you can break-in an engine on delo or you can't.

    Until then it's speculation so let's rather take the discussion to another thread ( I looked for one but found nothing so maybe we should start one )

    I still stand by the fact the I love delo 400 but would highly recommend anybody else to use their manufacturer recommended specs and methods.

    I'm doing it different for the hell of it

    4ePikanini - Park your horse, slow down and read the post!

    Nobody criticized you, nor your method of running in. There's also nothing wrong with the oil you used. In fact, all writings supports your way of doing it. You've done nothing different to the norm and is as such not sacrificing anything.

    The issue of a run-in oil was simply aired as a different way of doing it.

    Not to worry Botswana. No offence taken or meant.

    I'm just trying to avoid the thread running away with itself like my jetta one.
