DazC,
and the rest is anti-corrosion
my new engine management monitors oil pressure and I can set it to flag up a warning if it drops to a certain level or cut the car out completely if it drops even lower..
all for the price of a £20 oil pressure guage , ill have one !!!
Alvyn,
m8s got an electric senders type and as soon as his ignitions on ie b4 the engine starts turning it's reading oil pressure in the engine and once he had really low oil and the gauge was showing but when we pulled up the top end (cam followers) were well noisey on start up(Cossie) checked the dip stick and there was none on the stick so personal choice comes into play I think
a pressure guage is not designed to tell you when you need or dont need oil , by default it will do this , but thas only when it has no more lubricant to decide what pressure it at .
i can also never understand why people remove the oil pressure lamp and replace it with a guage
what is the easiest thing to see if you suspect a problem ? its not looking at a guage ( that aint accurate anyway cause you paid less than the price of gallon of oil for it) and trying to decide if its on 0.5bar or 1bar, whilst at speed going round a corner . all you need is a high pressure switch and a warning lamp.
