Oil pressure?
VWCOOL - July 16th, 2008 at 10:20 PM

What oil pressure should a healthy VW engine have? PSI and kilo-jobbies?

As far as i know

the engine oil pressure is 28 PSI Maximum
so I thought..

A Haynes manual says 28 PSI Minimum at 2500 rpm

Healthy as in good condition,
or healthy as in "GRRR"?


It is suprising how little you can get away with,
but Pauter told me to make sure I had 10psi per thousand rpm when I was supercharged.

I think a na engine could go as little as half that.

Although I like to see 50psi-hot at full steam on my own engine to make me feel safe.

well, as many VW owners know, that oil pressure in a hot engine [temperature] can drop very low at idle
like at traffic lights...

and the oil light can flash on...

lol... I have GRRR engine :lol: but not sure where the gauge shoudl sit - it's up and down like a yo-yo but I think the sender could be stuffed. Will fit a new sender unit and see where it sits...

as daves already said good rule of thumb is 10psi for ever 1000rpm at operating temp

the stock idiot light when functioning correctly is sposed to come on at 6psi
when cold the bypass valve should keep it under 70-80psi
too much pressure is just as bad as not enough

i made the mistake of running 20/50 GTX in my stock 1600 thinking thicker was better cos it was 10 years old
switching to penzoil 10/30 as even vw recomended that in summer for australia pressure INcreased and it ran cooler cos it was flowing thro the engine and oil cooler quicker and a bloke on samba said he got better MPG after the same change
