After my little race with my bro last night I've noticed that my oil pressure gauge is reading lower than usual.
The car does burn oil when the revs are high and I did need to top it up this morning. Drove araound for a while with the gauge showing max pressure (until it warmed up a bit) then dropped to half as usual.
After a short while longer, while sitting at some lights it dropped to 1 notch on the gauge. Normall it stays at half all the time. Drove around a bit more but noticed that the levels are one mark lower than usual. ie, at lights 1 to 2 marks, rather than 2 constant, and when driving 2 to 3 marks rather than 3 to 4 marks on the display!
Checked the oil when I got back and it was the same place it was before the trip!!
So, what would cause the oil pressure to be less after a good thrash the night before, what have I broken?
The car drives as before (if not a little better, which is a mystery) just the pressure gauge display.
