gas prices arnt too bad here in kentucky since the stock crash
they are around 1.55
but i know if the economy ever gets back on track, they most likele
will spike
so what are some things i can do to get more mpg out of my 4.3L 2001 vortec?
im getting bout 16 on highway

 

cold air intake is said to help mpg it helps my 4.3 get about 18-20 mpg highway. I installed an airraid cai. plus it helps make your engine sound a little beefier

 

ok cool
do you have a link
i might have to add one to my list lol

 

High Flow Air Filer, Car Tires vice truck tires, Synthetic Oil. Proper tire pressure at all times.

 

cool, ive never heard the car tire thing before
but i wouldnt try it because those tires are made for lightweight cars
and not suv's
is a k & n a high flow filter?

 

The tires that came standard on Blazers were 'car' tires, P-metric radials. 'Truck' tires would be LT radials. They have a higher load limit rating.

 

I am the original owner of my S15 Jimmy and it came with General Auto tires. K&N Air is a high flow air filter. Another inexpensive item is a fuel injector spacer. (Not A TBI Spacer). It alows for sllightly more airflow into the TBI. I average about 21 MPG. I have a stock exhaust, K&N Air Filter, Michelin X-Radial Tires, and Fuel Injector Spacer. Plus for highway driving I use cruise control as much as possible and try and avoid jack rabbit starts and stops.
