im getting the feeling that the wiring and connector to the pressure sensor is pretty turd and by the way mine sumtimes just drops to 0 and pops back up again it either means mine is suffering too or iv bought fizzy oil with bubbles in...
im thinking the 1st one is more likley,
also what pressure does people gauge read on tick over when its all warmed up,
Stock gauges are notoriously crap!!! but when they are working you should sit around the 2 mark at idle.
Just go for an after market one mate..... just for peice of mind!!
Jono
yeah mine hobbles about the 2 mark unless i get it really hot in which case it sits just above the bottom mark untill its calmed itself down a bit
im using castrol mineral oil in it at the moment, was gonna order sum stuff from the us, but i change it every 3k and cant justified spending the extra 20quid for somthing im gonna bin in no time at all
Its not the gauge its the oil presure sensor, replace it and all will be fine.
They are a lot of money from mazda but i have a few 2nd hand ones for less than mazda duz em for.
iv got a greddy one sat here its just not to high on my list of things to do lol
You can always swap the gauge and the sender and put the new gauge in the dash in the original position keeping the stock look without too much trouble, same with the water temp.
