Quoted from Nick Jones
Supercharge is the stuff.  300mls is enough.  Even that will give fairly scary (high) oil pressure when cold.


My oil pressure reads 80 from cold at startup and 1500 rpm on the gauge. Idles when hot around 30 PSI, but reads 55 at around 2000 rpm. Never had a problem with pressure just drinking a tad of oil

Quoted from dinger
Back in the 1960s  - Certain garages  offerred  a couple of shots of Redex  gratis with every gallon...

I was still doing that for my customers when I was looking after a forecourt in Suffolk in the mid 70's..  Old fashion pumps and Redex dispenser.

Ok, so I bought Wynns Supercharge and added the treacle in to a warm engine. Certainly when it's hot the oil pressure is approx 10psi more than before.
One very weird thing I noticed was that it seems to reduce the volume of the oil overall depending on temperature. Now I know this sounds odd..but am perplexed by what's now happening.
Originally my oil was bang on the line...I added the Wynns and it went slightly over the line. next morning I checked the oil and it was the same amount but below the line?? Thought soemthing had happended and I'd lost oil... Went for a run, waiting 10 minutes after turning the engine off to check and was above the line. 30 minutes later..on the line..and hour later below the line?? Seems very odd..any ideas?
Very repeatable results

Some viscosity modifiers have very high coefficients of expansion.  Sounds like what is going on here.  Some fully synthetic oils give the same effect.
