    JDM v7 STi motor no longer losing oil

    The EJ207 is my 4th EJ motor. The 1st 3 EJ engines used no oil.

    This one used a litre between oil changes until now, and for some reason it just stopped using it. It never leaked or burned blue, it just needed a top up quart between oil changes.

    Any reason why a used motor might use some oil at first, and then miraculously stop?

    Detergents freeing up the piston oil rings for one. PCV valve may have been sticking.

    Get it back onto the track - that'll get it back to using oil again. LOL
