I spent sunday with eddie mapping my car, all day my car had high oil temps up near the 130 c mark on the guage, a couple of time the oil buzzer can on warning of excessive temps. anyway it was put down to thrasshing it around London sitting in traffic etc. anyway on the journey home two hours of motorway driving at a steady 75 ish, the temp never moved above 100 c ish. since then i have driven here and there giving it a good thrashing. oil temps never above 100c again. until tonight left work drove steady for 5 mins then got stuck in traffic, oil temps soon started creeping up to the 125c ish mark the car has a mocal thermostatic sandwich plate and a pretty big oil cooler, both lines are hot so i know the oil is flowing thro the cooler. it also runs the gti oil/water cooler. water temps remain fine and the fan is working as it should be.
