I have a 1992 Ford Chateau Club Wagon with 5.8 Litre Engine
and heavy duty tow package with 98,000 miles on it.
It is stored in the winter and only gets used about 2000 Miles
per year and gets Once a year oil changes before I put it away
in the fall. This van will eat you out odf house and home
with the horrendous fuel mileage. I have used Castrol GTX
Pennzoil YB and Pennzoil HM all of which show the oil pressure
gauge varying constantly all over the place. I realize the
factory gauge is not the best in the world but when the needle
is reading below the N in Normal at highway speeds it makes
me nervous. After switching to Valvoline Max Life this problem
has disappeared. This engine holds good oil pressure all the
time. Why would there be such a difference ??
Also I use the Motorcraft FL1A Filter with each change
and heavy duty tow package with 98,000 miles on it.
