Gave the Jaguar a good wash today. No time for polish. Oil and water both looking good.
I've got Total LRP four star in at the moment and the car seems to start better. Mind you, it's much warmer weather too.
Went for a joy ride. Still fretting about that diff. After 15 miles it was almost too hot to touch and hold, but not quite. Hadn't kept off the brakes through the village, so it could be that heat transfer from the discs.
