In Europe we only use 20W-50 in the 2.8 Cologne.
I have several friends here in the Spanish Ford Capri club who all use 20W-50.
Valvoline VR1 20W-50 would be a great option.
Those Capris are some awesome cars! Thanks for the suggestion! Do you run it year round or old in the summer?
I live here on a rock in the middle of the Mediterranean so i can run it year round no problem.
My only problem is i can't really open it up for too long without getting a huge speeding ticket or falling into the sea.
Mine is the 3.0 Carburetted "Essex" V6 version with 144hp , not the Cologne you have, European 2.8 Capris have K-Jetronic fuel injection and 160 ( claimed ) horsepower ( in reality 150-155 ).
The most i have gotten out of mine was 127Mph, my friend Tony's 2.8 can do about 130Mph ( stock ) , the 2.8 Cologne has about 15hp more than the 3.0 Essex, but also has 15 lb/ft of torque less than the 3.0 Essex.*cough* This was obviously done on a private road with no traffic *cough*
