Cruising at 180km/h in 35 deg heat or similar shouldn't result in any issue with oil temp. It's not high revs (only about 4500 or so?) and there's massive airflow for the cooler. It's the hill climb scenario that really gets the temp up, revving out to redline time and again in 2nd/3rd gear.
That's what I mean, I get 5,400 rpm on 180 and the airflow is massive, even nice cool ocean air, outside temp. was 24 degrees
Now having learned that this "problem" crops up in Namibia (very often very hot), while driving at a sustained 180km/h for long periods of time, I am inclined to think that it is an actual overheating problem, not a dead sensor.
One thing I still wonder about is - doesn't the water temperature also go up?
PS: I would never buy that GT second hand.
LOL, Giorget2, you know you want it hahaha. Did you see how nicely I cleaned up the fuse box on top of the battery? You'd be proud of me.
No, the water temp. stays at 90, never goes over, ever. Normal crusing oil temp should be bar 4 or 120 degrees for optimal viscosity of the oil, right? Using 10W60
How long does it take for you to get 5 bars on the oil temp gauge, how many miles of driving?
When it is at normal 120 degrees it takes maybe 2-3 km's to go to 140 and another 2-3 to get to max, then I decelerate to 120km'h's and it takes again 2-3 km's to drop back to 120 degrees so it is a constant concertina dance in terms of speed.
