Engine Performance problem
1990 Jaguar XJ6 6 cyl Two Wheel Drive Automatic 200, 00 miles
I have heard that a car runs better and performs better with premium fuel vs convenience stop fuel. What is your opinion on fuel necessary to always have a excellent highway trip of 550 miles (round trip).
have the same problem?
