dumb question re oil pressure.
Discussion
Glad you've brought this up... was going to ask something about this myself!
Mine sit's at just above 50 most of the time, but occasionally drops to 50...
EDIT - Oh and there is no such thing as a stupid question Shnozz... only stupid people...

If you're at all concerned about your oil pressure then the sure fire way to reassure yourself is to book your car into a local garage and get them to check the pressure for you. They take out your pressure sensor and plug in their own and tell you the definitive oil pressure. This is what I did when I first got my car and although the guage wasn't that accurate (read low) the actual pressure was fine. It only takes a few minutes and doesn't cost much and will give you a lot of peace of mind.
In the end I replaced the sensor (pretty cheap) and the readings were more like what I was expecting.

Mine is around 50 at motorway speeds and drops to around 30 when idling. I am of the opinion that as long as you are getting pressure the oil system should be working ok. Don`t the v8s run at about 10-20? ould be wrong, but I`m sure I overheard a conversation about this once before.

I'm assuming you have read the "Bible" page 29 etc on oil pressure if not best gen up now.
Generally a consistently low or lower than normal oil pressure indicates engine wear, low pressure usually points to a worn crankshaft and big end bearings especially if the car has covered a high mileage. In some cases it may simply be due to a blocked oil filter or pressure relief valve which has stuck open.
If you are worried I would suggest the following.
(a) as the previous thread get a garage to check the accuracy of your gauge against theirs.
(b) put fresh engine oil in. (old oil is unlikely to give a good oil pressure.)
(c) know what your running/idle pressures should be from either the bible or TVR.
Are you burning oil? showing blue smoke? if not don't panic too much as many engines run at a fairly low oil pressure and are fine.

thanks again all - John Mac you are a font of knowledge!
I shall read up the relevant section in the bible. It doesnt seem to fluctuate a great deal so it would appear I do not need to be too concerned. I really posted due to my ignorance on what the gauge really meant, rather than just know it was oil pressure but not know what the reality of that was.
many thanks
