[Fot] Lucas Oil Stabilisator

[Bob Kramer]

If I remember correctly there are two formulations of STP, red and blue bottles. Only one has the ZDDP.

> It may have allowed your oil to aerate so your pump was trying to move oil with air bubbles in it.  It apparently has no anti-foaming additives, so when you add it to your oil, you are diluting the additives in the regular oil.  There was an article on the bobistheoilguy.com website some years back that showed in graphic detail what happens with this additive whether it’s used in a gearbox or an engine.  Unfortunately I can only find an archived version of this article and the photos are no longer visible.  The photos I remember showed the oil turning a much lighter color after it had been thoroughly agitated, which meant it was filled with air bubbles.  Air compresses, so I can see a connection between aerated oil and a drop in oil pressure.
