Hey everyone.
I just purchased this 98 civic Lx sedan 5speed D16y7 137k miles completely stock that has sitting for 9 months. Two tanks 25 mpg driving 3/4 slow my last tank I got 31.8 mpg what can I do to get better?
Just installed a vacuum gauge we will see how much better
Since I bought it I have done the following
Change all filters
( air fuel oil )
Oil change Mobil 0w 30 full synthetic
Pcv valve
Ngk V power plugs
Ngk blue plug wires (old stock ones resistance triple the ngks )
Clean throttle body
Seafoam heat soak
Valve adjustment
Lowered car 2in front and back
Limo tint all around
