Hi Chris,

Wow! I am really sorry to hear that! I feel your pain from here!

 

The advice you received seems to break the cardinal rule of NEVER EVER mixing mineral and synthetic oils! They are two completely different bases of stock. I’m not surprised that you had mechanical issues. 

 

Foaming suggests that the combination of the two distinctly different bases were not mixing. That’s expected. 

I would suggest that lubrication starvation, through oil emulsifying is most likely the culprit of your failure.

 

Mmm… A very simple error in advice has had dire consequences! Very, very frustrating.

Kind Regards

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.

 

Chris

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.
