Hiya folks,
been getting the car out bit more now we are having some decent weather and in the last week im getting nearly constant low oil pressure warnings on tickover when shes warm. took her out today got her up to temp then checked the dials.

water temp 91deg
oil temp 81deg
ticking over at 600-750 rpm =3/4psi oil pressure
850 rpm = 7psi
1000 rpm = 10/11psi
2000 rpm = 36/37psi

checked the oil seems fine a bit full if anything.
So does anyone have any ideas? is it a case of turning tickover up i should i get it checked out?
If so does anyone know anywhere in Mansfield-Nottingham area i could get it checked rather than taking it all the way to derby if its just a quick fix?
any help appreciated...

dont panic,I think. Mine did the same after I'd just bought it, it had just been serviced so all should have been well but, oh no, bleep,bleep,reset,bleep, SHUT UP!!!!
Took it back to dealer who were a little mifted to say the least, turns out it was fine after all, just a dodgey sender relaying wrong infomation....alls fine ..... no bleeps

Agree, sounds like the sensor/sender or just the tickover needing a tweak.

Derby isn't that far from Mansfield/Notts! Best get someone who knows the engine to check to be on the safe side.
