Wondered what the recommended oil for a uk turbo 97 (facelift if it makes any difference - guess prob not!) is? Got to drive 300 miles in it this weekend, and want to give it quick top off before we leave.
Starting to brick myself about the back axle now after reading a thread on here just now about leaky rear diffs seizing. Mine looks like it has weeped slightly, but doesn't make any noises. Be alright won't it?!!
