after reading a thread a couple weeks back I started filling up with
supreme and i am happy. i am getting 3 or 4 more mpg. But heres the problem
from full tank to half a tank i get 260 miles and from half a tank til the gas light
comes on i get about 100 miles...any ideas why this happens???
during this time my engine temp acts screwy. before fill up engine is
around 205*. i fill up sit back in the car and engine temps is 150*.
from full tank to half tank engine stays around 150* and once it gets around
half tank temp will go up to 175* . the temp will gradually increase up to 205*
by the time the gas light comes on.any ideas on why this is happening?
i have a 180* thermostat ..
