Hi all
I know someone did ask this once - as I did come across this on a 'search' before, but not having much luck finding it again tonight unfortunately! - but does anyone know what the ideal -ish! bar pressure should be?
Got a 1y, 1.9 diesel in a 85 Bilbo van, and just installed a 5 bar VDO gauge and got a reading of about 3.5 bar on cold start up -didn't get chance to see what it was when at full temp though! When at optimum temp?, seemed to remember someone saying here that you might expect it to be about 1 bar?
Anyone got any ideas please if this all sounds about right?
Thanks as usual for any replies
Cheers.
Brian
What should oil pressure be bar wise please?

Thanks for the reply guys. Hope haven't opened up a can of worms there with the oil ratio thang! Engine is actually from a Seat Toledo and I was told that 10/40 oil should be used by a vw garage for this one.
Had a quick look at the spec though - thanks - but couldn't really see in laymans terms about bar pressure?
So if anyone has any ideas still what roughly the bar reading at cold start up and then at full working temp should be, then that would still be appreciated.
Thanks all.

The bottom line when it comes to engine oil is as follows. Use the thinnest oil you can get away with yet still maintain a good oil pressure.
So if your getting about 2 bar when its warm with a 10W 30 that's ok if not then use a 10W 40.
Thicker oil means more friction (shear friction of the oil) and less power.
But in realistic terms, if the engine is good use 10W 30 if a bit tired opt for the thicker 10W 40.
