Hey guys i have a 90 4runner 3.0 v6 auto just on 31's why am i getting like 70-80 miles on a half tank thats the top half i have gave it a tune up ...it seems to run hot....... 254,000 miles on her any advice???? thanks
May possibly be the common head gasket issue with the 3.0 v6. That would cause for the poor mpg and running hot. Try a compression test to verify if it is a head gasket.
