Excessive Gas mileage

[Durace1]

Has anyone had a problem with MPG dropping to 16 when their 3.4 liter engine turn 70k?

I sure would like to have some excessive gas mileage but I am guessing you mean excessively poor. A tune up and some synthetic oil should help. A high quality synthetic atf or gear lube throughout should be good for at least 2 mpg. on the highway.

My MPG dropped also on my 3.4 with 75k. I hate to admit that mine is lower than 16MPG. This is my first toyota, just thought that's the way they are.

well mine was getting excellent mileage up
until the gas prices went up. i think they
are mixing something in with the gas so
it burns up quicker.

Yah, definitly time for a tune up. My dad's 2001 hit 100k last week and still getting the same mpg... friends dropped but not until 230k miles... keep the tune ups pretty regular and you shouldnt have a problem at all, same as all cars.

I got 22.4 MPG on a road trip this weekend in my 2004 Tacoma 3.4L V-6.
