So, I'm thinking of changing my oil.
It's been in about 1k miles.. but it's always ran hot.
80c in traffic, 100c normal driving, 120c on motorway..
Before I had engine out, it never went above 80c on the old oil (but it had seen better days), but then, the coolant never got hot either cus' of thermostat - got low temp thermostat now, and it gets up to right temperature.
Pressure, it sits at about 4 when oil is cold, sits at about 3k throughout rev range when up to temp (if oil is 80c, then it goes to about 3.5bar, motorway, it's about 3bar) and drops to just above 0 on idle..
Mat has exactly the same oil in his Hybrid, and that sits at 80c no problems.. so I dunno?
It just seems weird.. read somewhere that if oil hits 120c, then, it's probably buggered.. but I dunno how true that is.
Car performs awesome at the moment.. really responsive and torquey.. which is what worries me too.. heh.
Oil is 10w40, Vauxhall stuff.. not sure if semi or fully synth.
Should I change it?
If I do, what should I use?
