Hi.guys!
I have Blazer 2000,4*4.
The problem is low MPG:about 10 mpg in town and 15mpg highway.
How can i fix this Problem?
The car has 105k miles.

 

when i changed my air filter i got an extra 2 mpg's and it also increase acceleration for me

 

*Moving to 2nd Gen Tech* This section is more for motor hard part problems.

What have you tried? Tune up (plugs, wires, cap & rotor)? Any check engine light? Have you tried fuel from different stations? Have you used any fuel injector cleaner (I use Chevron Techron Plus Concentrate fuel system cleaner)?

 

I replaced plugs,fuel filter,air filter.some times(last month only) check engine light is shown.I put chevron techron today.
what is seafoam? Somebody told me about,but a don't find itin a store.

 

Here's the information about Seafoam.

 

they should have it at pep boys or adavanced is my store of choice. i swear by this stuff i got about 4 more mpgs, my oil pressure went up, and my truck stopped smoking. great stuff.

 

They do have it at pepboys
