Not if it were [made] for it.

I don't know how I got into this conversation, and I want out! :-\

All I ever wanted to say is that heat is the enemy of everything except gas
mileage. Engines are a compromise betwixt economy and durability. Everything
else I said was meant to show that, and I guess I botched it. :-)

Man, it's 86 degrees out and just beautiful. My wife drove the new Sonata to
a doggone hen party when we could be out driving it.

What sort of driving do you do? The only time my truck dropped to 11
MPG was when the temperature sensor failed and the ECM was running open
loop all of the time. The truck had great power, but it coated the
inside of the exhaust pipe with a thick layer of carbon so I know
something was up. Another common mileage killer as a bad oxygen sensor.
If you haven't replaced either of these, I'd suggest a visit to your
local dealer and have them check things with their scan tool. My
temperature sensor failure didn't illuminate the MIL light, but it was
detected immediately with their scan tool.

Pretty much all city driving, and I am always hauling something.
Whether moving relatives, carrying home a load of mulch or stone, or
transporting an ATV, I almost always have at least a few hundred pounds
back there.

I just replaced the coolant and temperature sensors about 2000 miles
ago. And I had the truck on the scanner at the local Chevy delaer then.
All checked out fine except for the coolant sensor.

From what I have read, this mileage is not that uncommon for an '88 305.
It was the first year they switched from a real carb, to some pseudo-
fuel injection system. In fact, 13-14 is very common, and considering I
haul a lot, that may account for the difference. I also have very old
gas in there, but I do use fuel stabilizer which helps I guess.

I probably need to take her out on the highway for a while and should do
that one of these days.

Even a moderate load of 600-800 pounds can really kill your mileage.
