[Fot] Lucas Oil Stabilisator

[MadMarx]

That was a good hind Duncan!

After the run I saw in the dry sump tank some foam on top.

Maybe a 0,5” thick layer.

I also removed some of the oil 2 or 3 hours later to give it to an oil specialist and while sucking it out of the tank I saw in the clear hose foam, oil and metal bits.

 

Thanks

Chris

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  Unfortunately I can only find an archived version of this article and the photos are no longer visible.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.

Hello Alex,

 

I was told to use mineral Lucas with synthetic oil. And so I did.

This stuff is stiff like frozen honey.

 

I suppose the lube went too stiff and the oil pump wasn’t able to force it through the system and opened the relive valve.

Hallo lieber Chris! Which Lucas stab did you use? There are two of them, mineral and synthetic.

Hi Guys,

 

by accident I found on my camera chip a video how I fill in two cans of Lucas Oil Stabilisator to 4 gallons of 10w60 oil of the IMSA TR8.

Listen to the difference.

The oil pressure dropped from 40 to 30 psi and never got over 40 psi on driving. Normally it is at 70 psi.

 

The engine died after 8 laps with bearing failures on all crank bearings and a worn out camshaft.

This has happened in April.

My engine man was ill for half a year now, but it seems that he’s getting back to work next week and tries to repair the engine.
