I recently bought a 95 s-10 pickup. 4x4 with a 4.3 vortex

First tank I got 21mpg, which was ok. My friend has same truck and gets
closer to 24 mpg. Mine has overdrive, and it runs great. But my last
tank of gas i got 15 mpg. No engine codes either. It had a tune up 2
years ago, is it time for another? What other things could I do? I
chenged the oil, and just put in new air filter. Thanks

I have an 02 s-10 with 4.3 vortec. I currently get 20 city and 26 highway. I
have a K&N air filter and a hypertec programmer in my truck. I am also
running Bosh platinum 4 plugs and duel exhaust. Have you checked your fuel
filter? Also that a/c will lower your miles if the compressor is pulling
hard. I am also running Bosh platinum 4 plugs. Check your pug wires and
distributer.
Hope this helps a little.

Of course, you have checked your tire pressure.
