Ways to increase fuel milage ?

[S13GG]

@KoukiS14

Change your oil out to something with a lighter weight. Go with a synthetic if you dont already run one. They can increase gas mileage by as much as 10%.

thats another good point, diff+tranny fluid,

but, jefro, my points were more towards reducing your drag coeffient,

slam that S13, (although you probably already have.)
