Hey guys, ive been getting shitty fuel mileage on my s13, i put in 20$ and get 140km. was just over 200 with 20$ i have searched and read other posts but got no useful information, except what common parts to change. i have changed plugs, all fluids,o2 sensor, cat seems to be ok not clogged, always run 91 vpower, i havent changed the distributor cap and rotor i dont know if it plays a big role in fuel mileage. Should i look into timing or the coolant sensor? sorry for making the post long thanks.

last time i remember I was getting about 200ish km on 87 regular in my KAE, you can always do a fuel injector clean, or try changing gas stations. I always use Sunoco, and will continue once I go KA-T this april or early may.

check your ecu for codes, good place to start. its behind the passenger footwell kick panel, pull it out and you’ll see a little dial on the back and 2 led’s. turn the dial all the way clockwise until the led’s flash 3 times, then turn it all the way back. after you do this it will flash back a code at you. the red led indicates the first number of the code, the green one the second number.

if you get 5 flashes from red and 5 flashes from green you have code 55 - this is means there are no codes present.

Give this a shot and post up what you find.

Good luck!

I usually get like 7km/L, about 350-400km per full tank. If I go all out ONLY highway driving, I get like 9km/L, about 450km per tank. This is with new O2 sensor, new cap & rotor, new plugs, new wires, 1 year old cat & manual transmission. wtf?

KA’s should get like 12+km/L on the highway (600ish km per tank), and about 10km/L in the city with efficient driving (500ish per tank)

There’s a KA-T dude getting like 12km/L, and I can barely get 8km/L with efficient mostly highway driving.

My calculations show about 19mpg, mostly highway, FAIL. I can’t seem to figure it out. I even used a multimeter to test my coolant temp sensor, it was fine. I cleaned my MAF with brake cleaner, and I commonly run injector cleaner as well.

tune it if you want better mileage guys, it’s all about the AFR’s in the end.

that would explain the KA-T dude getting better mileage 😉

AhmadG - Stop using the reverse of what everyone else does 😛 It’s either mpg or L/100km

FULL tune up. Fuel/air filter, wires, plugs, cap and rotor. Just DO IT!

Injector flush (fuel system service).

Check your coolant temp switch as well as your thermostat.

I can almost guarantee your having a temperature problem…
