Gas Mileage

Hey Guys!

I have a 2007 Tacoma 4x4 with the 2.7 motor in it and a 5 speed. It does not seem to get the gas mileage I use to. Are there somethings I can check to see if I can improve my mileage truck runs like a champ. It has 130k on it. I want to drive it till I can't anymore. Any suggestions I would appreciate. Thanks!

 

Plugs? O2 Sensor?

 

Do a full tune up.
-plugs and wires
-oil change
-belts
-make sure battery is good to go(water in battery, posts arr clean)
-pcv valve
-air filter
-fuel filter
-tranny and diff fluid change
-coolant flush
-change wheel bearing grease

Check anything that effects the health or your engine and anything mechanical that may impede the operation of your vehicle

 

Ok new battery and belt a few weeks ago. Due for regular oil change next week. Going to replace plugs and such next week. How do I change PCV valve? Coolant I just drain and replace with new right? How about tranny and differential oil? This is a 2007 standard transmission and 4x4

 

Check your tire pressure and add some if it is to low. Less rolling resistance.
