I'm the original owner of a 3.2 v6 rodeo... I've always changed my oil
on time, gotten tune ups at regular intervals, used either mid-grade or
supreme gas, and repaired any problems instantly. About 3 years ago I
had to take a job driving long distances and I could usually get
anywhere between 315 - 340 miles to the tank (actually when the empty
light would come on). But since my truck has crossed the 175,000 mile
mark I've been lucky to get 250 miles to the tank and actually seem to
be averaging around 215. Is my truck just getting old or is there some
potential problem I should be aware of that could be causing this drop?
Many shops do not recommend cleaners. While they can help clean the
injectors, they also tend to damage the injector seals making them leak
over time. If the vehicle is high mileage they may be leaking already.
Smelling faint gas fumes especially when the engine is cold is a
common sign of leaking injector seals.
Just out of curiosity... you wouldn't happen to have any idea which I
would need (I've never changed an O2 sensor before)?
I see the following Standard Motor Products: Upstream Sensor MT,
Upstream Sensor AT, Downstream Sensor MT, Downstream Sensor AT. And
then I see an AC Delco HTD Oxy OEM Sensor, part #AFS105.
