15 miles at warp 10 on a motorway will get the engine hot enough to boil off the water. Even with a thermostat, it will take some time to get the oil really hot. Other reason not relevant here is massive ingress of iron oxide from burning out bearings.....more often seen as rusty looking grease around destroyed wheel bearings. If you see that rust colour in the grease, look harder for the rollers or ball bearings that have pitted.
If you have it parked up, not using it but starting it for a short period it's not getting hot enough and a creamy sludge forms from the water in the crankcase. You probably need to give it a good run, not easy at this time of year for you..Any snow there yet..
Snow on the high mountains but here at 1500m not yet. Won't be long though...then we'll be in snow for 4 months.
You mean ALL Alfa's i've had 2 X 145 cloverleaf a 156 and a 147, they all broke, or in the case of the 156 engulfed in flames on the M62 at 80 mph
Yikes!! i had 2 x alfasud sprints. Only one was mayonnaisy but it still drove fine so may have been remnants of a previous owner problem.
