California 4KSQ owners
Wanted to check if another other 4k/4ksq owners are having the same problem
as i am.
My 85 4ksq has 150K on the dial, 2nd owner since feb96. In the past I've
been getting about 26mpg on the freeway and 20mpg in the city, and
23.5mpg combined, approximately. The last couple of months, my freeway mpg
has come down to 21.5. The car recently went thru a 30k service which
included the ox sensor, air, fuel filter, and plugs. The timing and
air/fuel mixture is dead on, and there are no vaccum leaks and the car is
still getting 21.5mpg on the freeway!
Question, has any other CA owner experienced any of this? Could the new
formulate fuel in CA be the problem? Have been told that the new
formulation could cause leaks in the fuel line of older cars. Any thoughts?
This is the first winter i've owned the car, but it only gets into the low
20's on the coldest night. Think the weather could explain my problem? Any
help would be much appreicated! Thanks
