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
